SO G. King— Materials for a Flora of the Malayan Peninsula. [No. 1, 



easily overlooked. There are, however, very few specimens without stipela on some 

 of their leaves and the writer has therefore followed Mr. Kurz in referring the 

 plant to Spatholobws. The matter cannot, however, be conclusively settled till pods 

 are obtained and examined. The only other species with equally obscure stipels is 

 8. crassifolius, of which, however, Mr. Baker has seen immature fruit. 



8. Spatholobus Ridleyi Prain. A climber with glabrous slightly- 

 angled branches. Leaves 6 in. long; leaflets 3 subequal oblanceolate 

 apex acuminate tip mucronulate base cuneate, papery quite glabrous on 

 both surfaces, 3-3*5 in. long 1-125 in. wide ; petiole glabrous 1*5 in- 

 long, petiolules glabrous 2 in. long ; stipels small rigid subulate, often 

 very obscure ; stipules lanceolate "25 in. long subrigid parallel- veined. 

 Inflorescence in axillary racemes 3 in. long 1 in. wide, bracts and brac- 

 teoles minute deciduous. Calyx *12 in. campanulate adpressed-pubescent, 

 upper tooth truncate the others rounded half as long as tube, pedicels '2 

 in. long, adpressed-puberulous. Corolla 25 in., white, standard orbicular, 

 limb slightly auriculate, apex retuse. Pod 4 in. long, I in. wide below, 

 seed-bearing tip '4 in. across ; sparsely puberulous, reticulate-veined, 

 semitransparent except at apex. 



Singapore ; 'Ridley 6401 ! 

 A very distinct species though nearest to 8. macropterus Miq. 



23. Indigofera Linn. 



Herbs or shrubs more or less densely clothed with adpressed hairs, 

 with (in Malayan species) compound odd-pinnate leaves. Flowers small 

 in copious axillary racemes. Calyx minute campanulate ; teeth 5, sub- 

 equal or the lower longest. Corolla caducous, standard obovate ; keel 

 straight, not beaked, laterally spurred near base. Stamens diadelphous, 

 anthers uniform apiculate. Ovary sessile many-ovuled ; style short 

 incurved, stigma capitate penicillate. Pod linear-cylindric several-seed- 

 ed. Species about 250 ; in all tropical regions and in temperate South 

 Africa. 



The genus is hardly a Malayan one ; the above definition applies, as to foliage, 

 only to the species that occur in the Malay Peninsula.
