STIZOLOBIUM PRURITUM BIFLORUM n. comb. 



Mucuna pruriens biflorum Trimen, Handbook Flora Ceylon 63: 1894. 



Seeds black, shiny. 



Trimen's original specimen from Batticaloa, Ceylon, is preserved in tbe 

 herbarium at Perideniya and from it the following notes were taken. 

 " Leaflets very silky beneath, 3-4 cm. long. Pods falcate, 5 cm. long, 

 with a single stont rib extending from the tip nearly to the base, the 

 whole pod covered with red erect stinging hairs. Seeds 5, black, shiny." 



The specimen is from a rather weak plant as indicated by the small 

 leaflets and the 2-flowered clusters, a common phenomenon on weak 

 plants in the related species. 



Identical with Trimen's plant are S. P. I. Nos. 26,183 and 29,907, both 

 received through Maj. A. T. Gage, Royal Botanical Garden, Sibpur, Cal- 

 cutta, India, and No. 24,935 from C. Drieberg, Esq., Secretary, Ceylon 

 Agricultural Society, Colombo. 



Herbarium material of the same thing has been examined at the Royal 

 Botanic Garden, Calcutta, as follows: 



Perak, Straits Settlements, L. Wray, February, 1889, No. 3326. "Kum- 

 bang Kota." 



Palkate 2000 Lohardryga, C. B. Clarke, October 30, 1883. (This prob- 

 ably means between Palketand Lohardaga, Bengal.) 



Sti/.olobium microspermum n. sp. (§ Brachyule). 



Stems twining to a height of 2-3 meters, annual, slender, terete, striate 

 angled, retrorsely pubescent; leaves trifoliolate, the petiole pubescent 

 like the stems, 6-10 cm. long; petiolules fleshy, pubescent, about 6 mm. 

 long; leaflets ovate-lanceolate, the lateral oblique, acute, 4 to 10 cm. 

 long, about equalling the petioles, the pubescence fine, appressed, denser 

 and silky beneath; pods 5-seeded, 7 cm. long, with 2 complete or nearly 

 complete longitudinal ridges, and constricted between the seeds; hairs 

 rusty red, closely appressed, rather dense with silky sheen; internal par- 

 titions nearly complete; seed black or nearly so, oval, much flattened, 9 

 mm. long, 6 mm. wide, the hilum 6 mm. long, surrounded by a very small 

 paler caruncle. 



From the botanical garden at Buitenzorg, Java, S. P. I. Nos. 32,112 

 and 24,423, cultivated at Biloxi, Miss., Miami, Fla., and in the green- 

 house at Washington, D. C. The type is a specimen of 32,112 grown at 

 Miami, Fla., in 1914, and preserved in the Economic Herbarium of the 

 U. S. Department of Agriculture. 



Very closely related to S. pruriens but with much smaller pods and 

 seeds. 



Stizolobium venulosum n. sp. 



Stems herbaceous, finely canescent; leaves trifoliolate; leaflets 5-8 cm. 

 long, firm, ciliate, rather obtuse, cuspidate, nearly glabrous above, 

 strongly reticulated and finely hirsutulous beneath, the veins prominent,
