Herbs, shrubs and rarely trees, monoecious or dioecious. Indumentum of dense velvety hairs, sparse simple straight or recurved hairs, stellate hairs, capitate trichomes, sessile glands or absent. Stipules persistent or caducous, narrow to broadly triangular, elliptic or ovate. Leaves alternate, simple, symmetric; petioles short to exceeding blade length, blade surface without glands; base acute, obtuse or cordate, sometimes with a pair of glands; margin serrate, crenate or subentire; apex acute to acuminate; venation distinct, penninerved or palminerved at base, looped and closed near margin (semicraspedodromous), tertiary veins and veinlets scalariform to reticulate. Inflorescences unisexual or bisexual, axillary, terminal or both, solitary or less commonly fasciculate, spicate or paniculate; bisexual inflorescences usually pistillate below and staminate above; staminate flowers in groups per node, pistillate ones generally single. Flowers petals and disc absent. Staminate flowers: pedicel short, elongating on maturity; calyx 4-lobed, midrib usually verrucate on upper half; stamens 8, thecae 2, pendulous and vermiform at anthesis; pollen small, oblate-spheroidal to suboblate in meridional outline, apertures 28-colporate, ectocolpi 15 μm; pistillode absent. Pistillate flowers: pedicel present or absent, subtended by a bract, latter either chartaceous and non-accrescent or foliaceous and accrescent, if foliaceous then with minute bract stipules; calyx 3- (or 4-) or 5-lobed; ovary 2- or 3- (or 4-)locular; stigmas 2, 3 (or 4), smooth, usually laciniate; ovules 1 per locule. Allomorphic flowers sometimes present, ebracteate, ovary 1-locular, variously fringed, styles subbasal. Fruits capsules, lobed, thin-walled, dehiscing partly loculicidal and completely septicidal and leaving a persistent columella. Allomorphic fruits nutlets. Seeds carunculate or not, caruncle if present covering up to basal half of seed, seed coat patterning indistinct. (This description pertains to the Malesian species only).
Distribution A pantropical genus of 450 species, with centres of diversity in Central America and Africa, and including 28 species in Malesia. The infrageneric classification follows Pax & Hoffmann (1924), with subg. Linostachys represented by 1 species in Malesia and subg. Acalypha by 27 species.
Notes
1. The staminate inflorescence technically is a spike-like thyrse in which the staminate flowers are shortly pedicellate and clustered in cymes along a rachis. However, for simplicity the term spicate is used here to describe the staminate inflorescence.
2. The term dots is used to refer to small light-coloured circular patches in the epidermis, less than 0.1 mm, that may represent druse crystals, but this was not confirmed anatomically.
3. Paired appendages flank the base of each foliaceous pistillate bract. Because the bracts are modified leaves, the subtending paired appendages appear to be homologous to stipules; hence the term bract stipules is used for these structures.
4. Pistillate flowers in subg. Acalypha generally are subtended by two orders of bracts, first order bracts and second order bracteoles. Bracteoles in subg. Acalypha are usually minute, bifid, membranous structures. In subg. Linostachys the pistillate flowers are subtended only by a single order of bracts. These are minute, bifid, membranaceous organs that structurally
appear to be homologous to the bracteoles of subg. Acalypha. Despite this homology, we consistently refer to first order bracts in both subgenera as bracts. Bracteoles are difficult to observe in subg. Acalypha and are not included in the descriptions of species in that subgenus.

Notes 1. The leaves of A. paniculata are similar to the leaves of herbaceous annuals like A. indica or A. lanceolata var. lanceolata. However, it is easily distinguished by its racemose or paniculate pistillate inflorescences, pedicellate pistillate flowers without foliaceous pistillate bracts, 5-partite pistillate calyx and fruits with capitate trichomes. The staminate inflorescences are also notably thin (11.5 mm wide), which also adds to its distinct appearance. This is the sole Malesian species from subg. Linostachys and could hardly be confused with other Malesian Acalypha species.
2. The name Acalypha racemosa was published twice without description (Wallich 1828, Baillon 1858). Thwaites (1861) cited Wallichs name when he validly described A. wallichii (often incorrectly spelled wallichiana), apparently as a substitute for A. racemosa. Thwaites cited several specimens as syntypes, but the selection of the Wallich collection as lectotype is the most logical choice.
3. The name Usteria racemosa Dennst. (1818: 31), usually interpreted as A. paniculata, has been determined to be Symplocos cochinchinensis S.Moore (Nicolson, Suresh &, Manilal, Interpr. Hort. Malab., 1988).
4. The specific epithet refers to the paniculate pistillate inflorescences.

Small trees, shrubs or perennial/annual herbs. Stipules persistent or caducous. Indumentum of simple or stellate hairs. Leaves petiolate, margin serrate, crenate or subentire. Staminate inflorescences spicate, always axillary in Malesian species, or unknown. Pistillate inflorescences spicate; bracts foliaceous or not, serrate, lobed or entire, non-accrescent or accrescent in fruit. Pistillate flowers (sub)sessile, calyx 3- (or 4-)partite. Bisexual inflorescences spicate, sometimes branched and the fertile portions spicate, usually pistillate below and staminate above, if staminate below then with a solitary terminal pistillate flower; pistillate bracts as in the pistillate inflorescences.

q = A. argentii; m = A. balgooyii, Μ = A. capillipes; ’ = A. floresensis;5= A. phyllonomifolia; = = A. spectabilis; u = A. stenophylla; «= A. zollingeri.
Habitat & Ecology Flowering: May. Altitude 700800 m.
Notes 1. Similar to the widespread A. lanceolata Willd. var. lanceolata, but hairy all over with velvety leaves, spicate to paniculate inflorescences with longer more robust staminate portions, and female bracts that are larger and very hairy. A. lanceolata Willd. var. lanceolata has practically glabrous leaves, spicate inflorescences that are never branched and with short staminate portions, the pistillate bracts are comparatively smaller and only sparsely hairy. Acalypha argentii is a rare species from Central Sulawesi and known only from the type collection.
2. The specific epithet is assigned in honour of Dr. George Argent, former head of Tropical Botany at the Royal Botanic Garden Edinburgh, who has done extensive floristic work in Malesia, particularly in Indonesia and the Philippines.

l = A. australis; 5 = A. pulogensis
Habitat & Ecology Roadsides; open areas.
Notes 1. Acalypha australis is similar to A. zollingeri with its large pistillate bracts, but A. australis has narrowly elliptic leaves and pistillate bracts with a distinct acute apex. It also does not possess the yellow refringent sessile glands and stellate hairs of A. zollingeri. Furthermore, A. australis is an annual herb whereas A. zollingeri is a shrub.
2. A widespread weed in East Asia, but known in the Philippines only from a single collection, Ramos 7800. This specimen has narrowly elliptic leaves and was considered a separate variety or forma from the ovate-leaved species commonly found in East Asia (Hayata 1904, Honda 1931). Differences in leaf width might be attributed to the varying light conditions in habitat, where narrow-leaved specimens tend to grow in light intense areas. No infraspecific categories in A. australis are therefore recognized in this revision.
3. See note 1 under A. indica.
4. The specific epithet refers to south, perhaps southern China, the type locality for the species.

Notes 1. Acalypha brachystachya bears superficial similarity to A. lanceolata var. lanceolata and A. indica, which are also weedy annuals, but it is distinct by its deeply lobed pistillate bracts. A. lanceolata var. lanceolata has shallowly toothed pistillate bracts, whereas A. indica has obtuse to subentire pistillate bracts. Allomorph morphology also differs among the three species. The allomorphs of A. brachystachya have lateral fringes that appear fused forming a single distal fringe, whereas the two other species exhibit distinctly separate lateral fringes. See also note 1 under A. indica.
2. Acalypha supera Forssk. (Fl. Aegypt.-Arab., 1775, 162) is interpreted by Govaerts et al. (2000) from its description as synonymous with A. brachystachya, as it is an older name it should have priority over brachystachya. However, the description is vague and no type was designated nor can any original material be found, so we are proposing that this name should be rejected (Sagun in prep.).
3. The specific epithet refers to the usually short inflorescences.

Notes 1. Key characters include 3-partite, non-accrescent pistillate bracts, and 3-locular fruits with septal thickenings. This species is similar to A. longispica and A. caturus, and a number of authors have subsumed A. cardiophylla into A. caturus. All three species have 3-partite, non-accrescent pistillate bracts, neither A. caturus nor A. longispica has densely hairy longitudinal ridges on the fruit, and A. caturus has bilocular fruits.
2. The variety A. cardiophylla Merr. var. ponapensis (Kaneh. & Hatus.) Fosberg (in Fosberg & Sachet 1980) occurs in Pohnpei, in the Caroline Islands.

Notes 1. Key diagnostic characters include bilocular fruits and 3-partite non-accrescent pistillate bracts. This species is similar to A. cardiophylla var. cardiophylla and A. longispica (see note 1 under A. cardiophylla var. cardiophylla).
2. The type for A. cinnamomifolia (Schlechter 17982) is a peculiar specimen with long and sparsely branched stigmas, which rarely occur in Malesian Acalypha, but in all other characters considered it is scarcely different from A. caturus. Until more specimens are available that show consistent differences between A. cinnamomifolia and A. caturus, the former name is synonymized and not considered as distinct species.
3. See also note 1 under A. floresensis.
4. The specific epithet is after the genus Caturus L. (Euphorbiaceae), which was later subsumed into Acalypha.

Notes 1. Acalypha floresensis, from Flores in the Lesser Sunda Islands, possesses distinctly petiolate pistillate bracts. This is a distinctive feature not found elsewhere in Malesian Acalypha or elsewhere in the genus in so far as we are aware. Airy Shaw (1982) was the first to notice the distinctiveness of the type specimen (Loeters 1840) and annotated it as Acalypha inter A. grandis et A. caturus fers intermedia. Acalypha floresensis resembles A. grandis Benth. in having velvety hairs on the lower side of the leaves and accrescent foliaceous pistillate bracts. The only similarity between A. floresensis and A. caturus is their ovate to elliptic leaves. Acalypha caturus is distinct by its bilocular fruits and non-accrescent pistillate bracts.
2. The specific epithet refers to the type locality, Flores Island in the Lesser Sunda Islands, Indonesia.

Notes 1. This species is similar to A. angatensis but different in having leaves that are 5-nerved at the base and almost orbicular. Acalypha grandibracteata also does not have the yellowish hairs of A. angatensis, and the otherwise staminate inflorescences do not terminate with a single ebracteate pistillate flower.
2. The specific epithet refers to the large pistillate bracts.

Notes 1. Key characters include needle-like stipules, short petioles not exceeding half of leaf length, and fasciculate staminate inflorescences. Acalypha hellwigii can be confused with A. amentacea var. amentacea with its chartaceous leaves and long pistillate inflorescences, but can be differentiated from A. amentacea var. amentacea instantly by its short petioles.

Notes 1. Acalypha indica is similar to the other weedy annuals in Malesia, A. australis, A. brachystachya and A. lanceolata var. lanceolata. They all have similar ovate to elliptic leaves (except for A. australis), foliaceous pistillate bracts, and bisexual inflorescences, but A. indica has shallowly toothed to subentire pistillate bracts and always terminal allomorphs that have shallow lobed lateral fringes and long pedicels. Acalypha australis has a distinct acute apical lobe on the pistillate bracts; its allomorphs have not been observed in Malesian specimens. Acalypha brachystachya has elongated bract lobes and its allomorphs have seemingly fused lateral fringes that appear as a single distal lobe. Acalypha lanceolata var. lanceolata has acute pistillate bract teeth and its allomorphs are subsessile, have deeply lobed lateral fringes, and are found laterally on the staminate portion of the inflorescence and are never terminal.
2. Seed development and allomorph morpho-anatomy was studied by Johri & Kapil (Phytomorphology 3, 1953, 137151).
3. Coode (in R.Antoine, Brenan & Mangenot, Fl. .Mascar. 160, 1982, 78) lectotypified A. indica, citing Herb. Linn. No. 1139.3. This is a specimen of A. lanceolata var. lanceolata, however, and so should be rejected in favour of Radcliffe-Smiths subsequent lectotypification (Radcliffe-Smith, Fl. Pakistan 172, 1986) of the specimen at the Hermann Herbarium in BM, which is also the basis of Flora Zeylanica (Linnaeus, Fl. Zeylan., 1747).
4. The specific epithet denotes the country India, the presumed locality of the type collection.

Notes 1. This species is similar to A. argentii and A. indica; see notes under these species.
2. The earliest effective lectotypification of A. lanceolata can be traced to Radcliffe-Smith (in Polhill, Fl. Trop. E. Africa, 1987), but the reference is in conflict with the protologue. The type chosen is an illustration in Thesaurus Zeylanicus: 205, t. 93, f. 2 (Burman 1737), but the figure is a Phyllanthus, and f. 1 is the Acalypha. However, the caption on the figure does not match the specimen examined by Willdenow. A specimen on page 101 of the Hermann Herbarium in the Bibliotheque de lInstitute de France (Lourteig, Taxon 15, 1966: 2332; Trimen, J. Linn. Soc., Bot. 24, 1887: 129155) matches the protologue and is chosen here as the lectotype in accordance with the provisions of the ICBN.
3. Another variety, A. lanceolata var. glandulosa (Mόll.Arg.) Radcl.-Sm. (Kew Bull. 44, 1989: 439454) occurs in Africa.
4. The specific epithet probably refers to the lanceolate or narrowly elliptic leaves.

l = A. australis; 5 = A. pulogensis
Habitat & Ecology Flowering: March. Altitude c. 2000 m.
Notes 1. Merrill and Quisumbing distributed specimens with an unpublished name. However, we decided not to use thisname due to its misleading connotation of obtusely undulate leaf margins, whereas the leaves are often serrate.
2. This species is similar to A. angatensis Blanco with its thick staminate inflorescences, and to A. amentacea var. amentacea in terms of its deeply toothed pistillate bracts and large practically glabrous stipules. However, A. pulogensis does not possess the velvety leaf lower sides and the boat-shaped stipules of A. angatensis. Acalypha pulogensis also has much larger pistillate bracts with dots and longer teeth, as opposed to the smaller, shallowly toothed, and undotted pistillate bracts of its close allies.
3. The specific epithet refers to the type locality, Mt Pulog, Luzon, Northern Philippines, the source of the only collection of this species.

Uses Often popular ornamental.
Notes 1. Key characters include variegated and often twisted leaves with distinctly serrate to lobate margins and deeply toothed pistillate bracts.
2. Various cultivars have been named under A. wilkesiana, but no infraspecific taxa within A. wilkesiana are recognized in this revision.
3. Acalypha wilkesiana is considered here as a distinct species and not as subspecies of A. amentacea (Fosberg & Sachet, Smithson. Contrib. Bot. 45, 1980) due to its diagnosable morphological characteristics and distinct position in the molecular phylogenetic analyses.
4. The specific epithet honours Charles Wilkes, head of the United States Exploring Expedition (18381842), during which the type was collected.
