the inner side of the style above the dense beard. Pod glabrous, straight or 
curved, about 3in. long, Jin. wide. — Dolichos luteus, Swartz, FI. Ind. Occid. iii. 
1246 ; V. retusa, Walp. Rep. i. 778 ; Harv. and Sond. FI. Cap. ii. 242 ( Scytalis , 
E. Mey.); V. anomala, Walp. Rep. i. 779 ( Scytalis , Vog.). 
Hab : Harvey’s Bay, R. Brown ; islands along the coast down to Moreton Bay, M'Gillivray, 
F. v. Mueller, Thozet, and others. 
The species appears to be not unfrequent in maritime sands in tropical Asia and islands of the 
Pacific, and in Southern Africa, more rare in the W. Indies. I have not seen Swartz’s specimens, 
but his description leaves no doubt that A. Gray is right in referring his plant to the present 
one. — Benth. 
3. V. luteola (pale yellow), Benth. in Mart. FI. Bras. Papil. 194, t. 50, f. 
2, and FI. Austr. ii. 260. Prostrate, trailing or twining, often hirsute, espe- 
cially when young, sometimes nearly glabrous, very rarely with a few of the 
centrally affixed hairs of V. lutea. Leaflets very variable, usually ovate or ovate- 
lanceolate, 1 to 2in. long, entire or slightly sinuately 3-lobed, the upper ones 
sometimes longer and narrower, almost always acute or acuminate. Stipules 
small. Flowers pale-yellow, in few clusters at the end of the peduncle. Calyx 
scarcely 2 lines long, the two upper lobes united into one very short and broad 
one, the lowest about as long as the tube. Standard 7 or 8 lines diameter ; keel 
as long as the wings, broad, much curved and rather acute, but not beaked. 
Stigma oblong, very oblique or quite on the inner side of the style above the dense 
beard. Pod hirsute or rarely at length glabrous, nearly terete, often torulose, 2 
to 3in. long, scarcely Jin. broad. — Dolichos luteolus, Jacq. Hort. Vind. t. 90 ; 
Vir/na glabra and V. villosa, Savi ; DC. Prod. ii. 401. 
Hab.: Endeavour River, Banks and Solander ; Burdekin River, F. v. Mueller. 
The species is common in tropical America and temperate N. America, chiefly near the sea ; 
it is also in tropical Africa. I have not seen any Asiatic specimens, which leads me to doubt in 
some measure the identification of the Australian ones. I can, however, detect no difference 
between them and some of the common American forms. — Benth. 
4. V. lanceolata (lanceolate leaflets), Benth. in Mitch. Prop. Austr. 350, 
and FI. Austr. ii. 260. Glabrous or slightly pubescent, short and erect or 
elongated and twining, but always more slender than F. luteola. Leaflets 
usually lanceolate, obtuse or rather acute, 1J to 2 or rarely 3in. long, entire or 
the terminal one hastately lobed on each side at the base, the lateral ones on one 
side only, those of the lower leaves sometimes short and ovate, in the upper ones 
long and linear. Flowers much smaller than in V. luteola, otherwise like them, 
in few clusters at the end of the peduncle. Calyx about 1 line long, the 2 upper 
lobes united into one very short and broad one, the lowest not so long as the tube. 
Standard about 5 lines diameter, with the 2 callosities and indexed auricles of the 
allied species ; keel broad, much incurved, rather acute, but not beaked. Pod 
glabrous or pubescent, nearly terete, 1 to 2in. long. — V. suberecta , Benth in Mitch. 
Trop. Austr. 388. 
Hab.: Endeavour River, Banks and Solander; Broadsound, R. Brown; Mount Owen and 
Mount Faraday, Mitchell; Archer’s Creek, Leichhardt ; Bowen River, Bowman. 
Var. Jiliformis. Stems long, slender and twining. Leaflets all linear or linear-lanceolate. 
Flowers smaller. I think fragments of this variety have reached me from the Gulf country. 
The pod in some of R. Brown’s specimens, with lanceolate leaves, is much flatter than in the 
other specimens seen in fruit, but I can detect no specific differences. — Benth. 
62. DOLICHOS, Linn. 
(From the long growth of some species.) 
Calyx-lobes short, the 2 upper ones united into one broad entire or emarginate 
one. Standard orbicular, recurved or spreading, with 2 indexed auricles at the 
base and 2 callosities inside ; wings obovate, falcate, adhering to the keel, nearly 
as long as the standard ; keel much incurved, often beaked, but not spiral. 
Upper stamen free, the others united ; anthers uniform, Ovary nearly sessile,
