452 PHANEROGAMIA. 



vexillar face densely and strongly bearded for a considerable length 

 below the stigma, which is lateral, but almost apical, since only a 

 minute lamellar appendage projects beyond it. Legume linear, elan- 

 gated, almost 3 inches long, 3 lines wide, manifestly flattened, straight 

 or nearly so, glabrate, somewhat torulose, intercepted between the 

 seeds. These are 8 or 10 in number, oblong-oval, compressed, chest- 

 nut-brown, shining ; the oblong hilum covered with an inconspicuous 

 strophiole. 



Without doubt, this well-marked species belongs to Vigna, as the 

 genus is received by Mr. Bentham, notwithstanding the compressed 

 legume and the straightish keel.

 the coast. (Probably introduced.) Mangsi Islands. 



The seeds are dark chestnut-brown. — Perhaps this passes into V. 

 Sinensis; but the leaflets are mostly roundish and very obtuse, espe- 

 cially when it grows on the sea-shore. I am doubtful whether it is 

 the /Scytalis anomala of Vogel, which also came from Oahu. 



In the collection from Sydney, New South Wales, is a flowerless 

 specimen, apparently of a Vigna, near the South African V. hirta, 

 and the Australian V. lanceolata, but not the same. It was also 

 gathered by Col. Mitchell.
