certainly refer the plant from Pahang to E. Bumphii as the fewer large 

 leaflets quite resemble those of Scheffer's figure ; the pod, however, 

 exactly resembles one. from the Andamans collected by Dr. Prain and 

 is also exactly like the figure of E. Pursaetha given by Seheffer. 



In examining specimens of E. Pursaetha in the Herbarium of the 

 Botanic Gardens, Singapore, and those lent me kindly by Dr. Prain, 

 I note a form in which the raehis of the inflorescence and the petiole 

 and midrib of the leaf are covered with a rather conspicuous tomentum, 

 reddish in the dry specimen, while the raehis in the other forms is 

 much more glabrous, though by no means completely so. These speci- 

 mens were collected in the Chittagong Hill Tracts (Lister 175), Manipur 

 (Watt 6726)., Silhet (Wallich), and Sikkim (Thomson), and probably 

 represent a local form. However, I have seen no fruit. 



The speeies from the Indian region and Malay Peninsula then are 

 E. Pursaetha DC, and E. spiralis n. sp. Further east we get E. Rumphii 

 Scheff. distinguished by its straight pod with obloug not rounded 

 joints, with a straight and not indented thickened margin, oblong seeds, 

 and thinner endocarp. I have also an evidently distinct species collect- 

 ed by Dr. Haviland in Sarawak on two occasions of which I have seen 

 no fruit, which I will describe under the name of E. homeensis. 



E. borneensis, n. sp. Leaves 4 in. long, with 6-7 pairs of leaflets 

 opposite or in the lower part of the leaf, alternate, oblong retuse, slightly 

 oblique, coriaceous dark shining above, when dry glaucous beneath, 

 petiole §th in. long, pubescent, midrib on both sides of the leaf 

 pubescent, I iu. long, and f ths in. wide j tendrils two on eaeh leaf. 



Inflorescence, one foot to one foot and a half long covered with 

 closely appressed pubescence. Flowers densely crowded, much smaller 

 ■than in the other species. Calyx cupulate with very short teeth, 

 pubescent. Corolla 5-lobed, lobes lanceolate acute. Stamens ten, fila- 

 ments as in E. Pursaetha ; anthers oblong. Pistil very rudimentary.; 

 female flowers and fruit not seen. Borneo, Sarawak, at Penkulu 

 Ampat (374), Saribas (1563, Haviland). 



This species is certainly most nearly allied to E. spiralis in its 

 opposite leaflets glaucous beneath, but is very distinct in having from 

 six to seven pairs, smaller, and pubescent on both sides of the midrib, 

 in the very much longer spikes of flowers which are not more than 

 half the size of those of E. Pursaetha or E. spiralis and the flower spikes 

 being unisexual. Dr. Haviland notes also that all the specimens are 

 male. The corolla in this species opens out quite flat starwise, not 

 merely reflexing its petals as in the other kinds, which gives it a very 

 different appearance. It is to be hoped that further explorations in 

 Sarawak will produce female flowers and fruit.
