A species characteristic of sandy seashores, widely distributed in the Philip- 
pines; Tropics of the world. 
0. Kuntze 83 reduces Vigna luteola Benth. and V. lutea A. Gray ( Dolichos luteus 
Sw. ) to Vigna repens (Linn.) 0. Kuntze ( Dolichos repens Linn.). Whether or 
not the reductions are correct I am unable to determine, but the specific name 
repens is invalidated in Vigna by V. repens Baker (1876). 
3. Vigna iuteola (Jacq.) Benth. in Tlxw. Enum. (1859) 90, and in Mart. FI.

Tropics of the world; Baker, certainly by error, describes the pods as one-half 
inch wide.

DOUBTFUL AND EXCLUDED SPECIES. 
Vigna repens (Grah.) Baker; F.-Vill. Nov. App. (1880) 65. A species defin- 
itely known only from Burma, to which F.-Villar reduced Dolichos repens Blanco 
(non Linn.). I am unable to determine Blanco’s species with satisfaction at the 
present time, although F.-Villar may have been correct in the reduction. 
Vigna vexillata Rich.; Perk. Frag. FI. Philip. (1904) 89. Credited to Min- 
danao on material collected by Warburg; I have seen no Philippine specimens 
that I consider referable to the species, and was unable to find Warburg’s specimen 
in the Berlin herbarium. 
88. DOLICHOS Linn. 
Style flattened, bearded along the inner edge; inflorescence of axillary, elongated, 
narrow, racemose panicles; flowers various, purplish, pink, white, or slightly 
yellowish; pods flattened, about 2 cm wide 1. D. lablab 
Style filiform, not bearded on the inner edge, but usually so at the apex; flowers 
few, in short axillary racemes; pods less than 1 cm wide. 
Glabrous or only slightly pubescent; leaflets lobed or repand; flowers pink. 
2. D. falcatus 
Softly pilose with long, spreading, white hairs ; leaflets entire ; flowers yellow. 
3. D. uniflorus
