This endemic, monotypic genus is undoubtedly closely allied to Canavalia, 

 and even more closely to Diocleo, to the latter genus especially by its staminal 

 characters, the fertile anthers being reduced to six. It seems, however, to be 

 distinguished from Dioclca, as well as from Canavalia, by its calyx characters. 

 The probability of the plant representing a new genus was suggested to me by 

 Doctor Prain in January, 1906, to whom a duplicate of Borden's specimen had 

 been sent for identification. Regarding this specimen. Doctor Prain wrote as 

 follows: "I do not agree with you in thinking that it is a Dioclca. The leaf is 

 wonderfully suggestive of Canavalia, but I should not be surprised, wiien fruit 

 is found, that you have near a new genus. It should be in tlie neighborhood of 

 Dioclca and Canavalia." The fruit is as yet unknown.

A woody vine reaching a height of 10 m, nearly glabrous. Stems 

 grayish, glabrous, terete, lenticellate, the shoots also glabrous. Petioles 

 12 to 15 cm long, slightly hairy or ultimately glahrous, each subtended 

 by a pair of pubescent stipules which are attached by their central part, 

 the lower part produced at nearly i-iglit angles from the upper, both free 

 parts less than 5 mm long. Leaflets ovate-elliptic, chartaceous, some- 

 what shining wlien dry, of the same color on both surfaces, glabrous, or 

 the lower surface with a few scattered hairs especially on tlie midrib and 

 nerves, 10 to 15 cm long, G to 10 cm wide, base rounded or acute, the 

 apex abruptly and rather slenderly acuminate; nerves 8 to 10 on each side 

 of the midrib, prominent; petioliiles puljcscent, ."i to S mm long; stipels 

 acicular, pul)escent, nearly as long as the petiolulcs. Racemes up to 40 

 cm in length, glabrous below, above, at least when young, ferruginous- 

 pubescent, flower-bearing in the upper half, the nodes produced as club- 

 shaped branchlets which become stout and woody in fruit and nearly 

 1 cm long, each bearing several flowers, and each subtended by a linear- 

 lanceolate, deciduous, acuminate, 5 mm long, pubescent bract. Flowers
