Ploem, Joannis (or Joannes) Carolus

(Source: Flora Malesiana ser. 1, 1: Cyclopaedia of collectors)

Born: 1819, Gulpen, L., Holland. Died: Nov. 24, 1881, Sindanglaja, W. Java.

career:

Physician; he was appointed in the D.E. Indian Army in 1851 and came out to Java in 1852, stationed successively at Willem I (Ambarawa) and Salatiga, both in Central Java. He resigned in 1853 and settled at Solo, where his practice did not answer expectations, however. He applied himself to oyster-culture, was forced by the government to discontinue his endeavours, and then erected barracks at Sindanglaja when the hospitals at Batavia and Buitenzorg were short of space. He was a lover of nature and since 1857 a member of the ‘Natuurkundige Vereeniging’ at Batavia.

Scleria ploemii Boeck. was named in his honour.

Collecting localities:

Centr. Java: Salatiga ( ? 1852-53).-E. Java.²-W. Java: collecting at Bandoeng, Radja Mandala, Sindanglaja, G. Gedeh (the caldera on Sept. 18, 1866),¹ G. Pangrango, G. Salak, Tjidamar, Tjikalong, Wijnkoopsbaai (= Palaboehan) (1870).-Outside Java he collected in Singapore (1867 or 1870) and visited Banka and Sumatra in Dec. 1878.³

collections:

Herb. Bog. [BO]: > 388 nos, partly numbered in the H.B. series; many of his plants labelled Sdl (= Sindanglaja). Duplicates in Herb. Leiden [L] (partly purch.); Herb. Berl. [B]: 204 nos from Java (pres. 1871) and 26 nos from Singapore and collection of mosses; Herb. Brussels [BR] (few); Herb. Paris [P] (few); U.S. Nat. Herb. Wash. [US]: 17 from Java.

Herbarium of Ploem from Java was sent to a certain Westerman, who presented the same to Prof. C.A.J.A. Oudemans, Amsterdam (= Herb. Univ. Amsterdam). From the spores gathered from Ploem’s fern specimens the Superintendent of the Amsterdam ‘Hortus botanicus’ succeeded in raising a number of ferns which were further cultivated. Oudemans subsequently donated the material to the Leiden State Herbarium [L] (information from a letter from Oudemans to Treub!).

His labels apparently often bear incorrect localities.

In Herb. Leiden [L] several Cyperaceae are provided with an impress ‘Sumbawa Ploem’; it seems improbable that they were collected in that island by Ploem himself, it might be material of Colfs (see there).
