RUMPHIUS'S HERBARIUM AMBOINENSE 



August and September, 1913, on wooded hillsides and river banks, altitude 



20 to 250 meters; Teysw.ann. Cultivated in the botanic garden at Bui- 

 tenzorg, from Amboina, under the native name geloba. 



A critical examination of two authentic specimens in the 

 Buitenzorg herbarium labelled by K. Schumann "Bearbeitet fur 

 das Pflanzenreich, ,, both from plants cultivated in the botanic 

 garden, shows them to be different from each other. One of 

 them is wrongly labelled "Donacodes minor" and is apparently 

 D. elongata T. & B. The other is the type specimen of D. 

 incarnata T. & B., a native of Amboina; this is identical with 

 Robinson's Amboina material and is easily distinguished from 

 D. elongata T. & B. by its densely tomentose ligule. Donacodes 

 elongata T. & B. and D. incarnata T. & B. are nomina nuda, 

 and the latter is apparently identical with Globba longa Rumph. 

 Older names are Amomum rumphii Smith and Elettaria musa- 

 cea Horan., both based on Rumphius. K. Schumann was wrong 

 in referring Globba longa Rumph. to Amomum TQseum (T. & 

 B.) Benth. & Hook. f. 



AMOMUM sp. 



Globba crispa I viridis Rumph. Herb. Amb. 6: 137, t. 61, f. 1. 



This Rumphian species has not been located, yet the descrip- 

 tion and figure are so good that it could not readily be overlooked 

 had a plant presenting its characters appeared in modern collec- 

 tions from the Moluccas. Willdenow, Sp. PL 1 (1797) 8, after 

 Koenig, placed the Rumphian species as a synonym of Amomum 

 echinatum Willd. Willdenow's species was based on Koenig's 

 Amomum 2 or Globba crispa, a native of Malacca; the latter 

 has tubercied, not aculeate, fruits and a filiform rhizome and 

 differs totally from Globba crispa Rumph. Amomum echinatum 

 Baker, of Ceylon, described also by Trimen under this name, is 

 still another quite different species, with copious curved spines. 

 Loureiro, Fl. Cochinch. (1790) 4, referred Globba crispa Rumph. 

 to Amomum villosum Lour., where it manifestly does not belong. 



AMOMUM sp. 



Globba silvestris subterranea Rumph. Herb. Amb. 6: 142. 



Amomum hochreutineri VaL, a species with white subter- 

 ranean fruits, as described by Rumphius, occurs in the mountains 

 of western Java. It is allied to Amomum hypoleucum Thw. and 

 like the latter is characterized by the silvery lower surface of the 

 leaves ; it is assumed that Rumphius would have mentioned this 

 character had he intended this species. Hasskarl thought that 

 it might be near Amomum gracile Blume.
