RUMPHIUS'S HERBARIUM AMBOINENSE 



in Journ. As. Soc. Beng. II 10 (1914) 23. The original reduction 

 of Rumphius's plant was made by Linnaeus, in Stickman Herb. 

 Amb. (1754) 23, Amoen. Acad. 4 (1759) 131, Syst. ed. 10 (1759) 

 1293, and has been accepted by most authors. The forms de- 

 scribed as album, rubrum, and fuscum are probably but variants 

 of the same species.

Dioscorea triphylla Linn., Sp. PL (1754) 1032, typified by 

 Rheede, Hort. Malabar. 7 : 63, t. 33, is merely a form of Dioscorea 

 pentaphylla Linn, and must be considered as a synonym of that 

 species. Prain and Burkill, however, propose to cite Dioscorea 

 triphylla Linn, as published in Stickman, Herb. Amb. (1754) 23, 

 Amoen. Acad. 4 (1759) 131, thus typified by the Rumphian 

 figure, and to retain Dioscorea triphylla Linn, as a valid species. 

 This usage is inadmissible, and the specific name triphylla Linn, 

 should be dropped. The oldest valid specific name appears to be 

 Dioscorea hispida Dennst.

Ubium nummularium Rumph. was originally and erroneously 

 reduced by Linnaeus to Dioscorea villosa Linn., in Stickman 

 Herb. Amb. (1754) 24, Syst. ed. 10 (1759) 1294; but in Amoen. 

 Acad. 4 (1759) 133, it was erroneously referred to Smilax china 

 Linn, by confusion with the preceding plate. It is the whole 

 basis of Dioscorea nummularia Lam., the Rumphian figure and 

 description being the type of that species. "Dioscorea num- 

 mularifolium Linn." as quoted by Henschel does not exist 

 and is a manifest error, the intention being Dioscorea num- 

 mularia Lam. The species is well known, being widely dis- 

 tributed in the Philippines and the Moluccas and extending to the 

 southeast as far as New Guinea and Prince of Wales Island.
