RUMPHIUS'S HERBARIUM AMBOINENSE 



Indo-Malayan representatives of the group are called by some 

 botanists. More than one species may be included in the de- 

 scription, Hasskarl, Neue Schliissel (1866) 51, definitely stating 

 that three are represented; namely, Cedrela toona Roxb., C. 

 febrifuga Blume, and C. inodora Hassk. Roxburgh was the 

 first botanist to recognize the approximate position of Surenus 

 and reduced it to Cedrela toona Roxb., in Fl. Ind. ed. 2, 1 (1832) 

 635. The typical form of Roxburgh's species is confined to 

 India, but a few varieties occur in the Malay Archipelago and 

 in Australia.* Surenus alba Rumph., Herb. Amb. 3: 126, is con- 

 sidered by Hasskarl, Neue Schliissel (1866) 51, to represent 

 Cedrela inodora Hassk., which species C. de Candolle treats as a 

 variety of Cedrela febrifuga Blume; Cedrela febrifuga Blume 

 var. inodora (Hassk.) C. DC, Records Bot. Surv. Ind. 3 (1908) 

 373. Hasskarl also refers to Cedrela febrifuga Blume the form 

 described by Rumphius as Surenus rubra Rumph., Herb. Amb. 

 3: 126, which is probably the correct disposition of it. The 

 oldest specific name, that supplied by Swietenia sureni Blume, 

 is here adopted.

This species is not represented in our Amboina collections. 

 The description, but to a less degree the figure, given by 

 Rumphius is clearly Xylocarpus {Carapa) obovatus Juss., as cur- 

 rently interpreted, but Xylocarpus obovatus Juss. is apparently 

 identical with the earlier Xylocarpus granatum Koen. In 

 Rumphius's description the shape of the leaves, rounded at the 

 apex, and the size of the fruits, indicated as larger than those of 

 Granatum litoreum I latifolium, are the determining points. 



The synonymy between Xylocarpus granatum Koen. (X. obo- 

 vatus Juss.) and X. moluccensis Lam. as interpreted below, is 

 curiously confused. C. de Candolle f recognizes the two species 

 Carapa obovata Blume and Carapa moluccensis Lam., but 

 erroneously reduced Xylocarpus granatum Koen. to Carapa
