RUMPHIUS'S HERBARIUM AMBOINENSE 



From the rather full data given by Rumphius I am unable to 

 distinguish from this species the form described by Rumphius 

 as Cacara pilosa. He contrasts it with Cacara nigra, but ap- 

 parently considered it distinct from the latter chiefly because 

 it was a wild, not a cultivated plant. Henschel, Vita Rumph. 

 (1833) 181, erroneously cites the name Cacara pilosa as a syn- 

 onym of Phaseolus pilosus Klein and erroneously cites t. 1U2 

 (=Mucuna pruriens DC.) as representing Cacara pilosa. As 

 noted by Hasskarl, Neue Schlussel (1866) 136, it is close to 

 Mucuna utilis Wall., but that species has the pods covered with 

 a tawny pubescence. It differs from Mucuna velutina Hassk. 

 in its purple, not white flowers. The chief objection to the iden- 

 tification of Cacara pilosa Rumph. with Cacara nigra Rumph. 

 = Mucuna aterrima (Piper & Tracy) Merr. is that Rumphius 

 describes the former as having more pubescent leaves than the 

 latter.

 Amboina, Toelehoe, Paso, and Amboina, in thickets at low altitudes and 

 along the beach, Robinson PL Rumph. Amb. 397, November, 1913. 



Parrana rubra Rumph., one of the "sea beans," is fairly well 

 described but very poorly figured by Rumphius. It has remained 

 doubtful up to the present time, but I feel confident that it is 

 the widely distributed Dioclea reflexa Hook. f. in spite of the 

 poor figure. Miquel thought that the figure represented a species 

 of Mucuna, and Teysmann thought it was a species of Derris. 

 The description of the seeds applies closely to those of Dioclea 

 reflexa, but the figure does not show their peculiar hilum 

 character.
