RUMPHIUS'S HERBARIUM AMBOINENSE 



ever, by Poiret, de Candolle, Don, Dietrich, Miquel, and a few 

 other authors. Malaparius, however, is no Pterocarpus, but is 

 manifestly identical with the plant commonly called Pongamia 

 glabra Vent. The Rumphian figure is an excellent one, and the 

 description applies perfectly except as to the statement that 

 the fxowers are yellow; this may have been due to a mixture of 

 material, or Rumphius may have had old flowers. The flowers 

 are usually white or pink, turning somewhat yellowish in age. 

 Prain, Journ. As. Soc. Beng. 68 2 (1897) 95, seems to have been 

 the first author correctly to reduce Malaparius to Pongamia. 

 Malaparius flavus Miq., Fl. Ind. Bat. 1 (1858) 1082, based on 

 Sumatran specimens, the generic name from Rumphius, is ap- 

 parently the form of Pongamia pinnata (Linn.) Merr. described 

 by Hasskarl as Pongamia xerocarpa (P. glabra Vent. var. xero- 

 carpa Prain) . 



I have taken up the earliest Linnean specific name for this 

 widely distributed species, as I am now convinced that the speci- 

 men in the Linnean herbarium, which is the common Pongamia 

 glabra Vent., is the actual type of Cytisus pinnatus Linn., as 

 indicated by the fact that Linnaeus not only gives a biblio- 

 graphical reference to Plukenet, but also adds a short descrip- 

 tion manifestly taken from an actual specimen.

Rumphius's figure is an excellent one of the widely distributed 

 form commonly known as Derris uliginosa Roxb., but for which 

 I maintain the earlier name, Derris trifoliata Lour. Loureiro's 

 type is not extant, at least no specimen of his species is among 

 his plants in the herbarium of the British Museum. Dalbergia 

 heterophylla Willd. is exactly the same as Derris uliginosa Roxb. 

 and has priority over Roxburgh's name in case Derris trifoliata 

 Lour, be abandoned. Hasskarl, Neue Sehlussel (1866) 93, re- 

 duced Tuba siliquosa Rumph. to Derris forsteniana Blume, which 

 is a synonym of the above species.
