Timor Ladt. — A common sea-coast plant in warm countries of both hemispheres, 

 including many of the Pacific Islands, from the Fijis to the Sandwich Islands. It is often 

 associated with Canavalia obtusifolia and Ipomcea pes-caprce. 



Vigna luteola, Benth. 



Vigna luteola, Benth. Fl. Austr., ii. p. 260 ; Hook, f., Fl. Brit. Ind., ii. p. 205 ; Oliver, Fl. Trop. 

 Afr., ii. p. 205. 



Timor Laut. — This likewise is a very widely spread plant, though not so common as 

 Vigna lutea. Besides these two very common species there are several others spread over 

 the warm regions of both hemispheres, including two endemic in the Sandwich Islands. 



Psophocarpus tetragonolobus, DC. 



Psojihocarpus tetragonolobus, DC. ; Hook, f., Fl. Brit. Ind., ii. p. 211 ; Miq., Fl. Ind. Bat., i. 1, p. 181. 



Timor Laut. — A commonly cultivated herb, and occurring in a wild state from Timor 

 to the Philippines and India. The genus comprises four species, natives of Tropical Asia 

 and Africa. Psophocarpus longepedunculatus is even more widely diffused as a colonist 

 escaped from cultivation. 



Dolichos lablab, Linn. 



Dolkhos lablab, Linn.; Hook, i., Fl. Brit. Ind., ii. p. 209; Oliver, Fl. Trop. Afr., ii. p. 210; H.

 Lablab vulgaris, Savi; Seem., Fl. Vit., p. 62 ; Miq., Fl. Ind. Bat., i. 1, p. 189. 



Timor Laut. — Cultivated generally in the tropics, and also existing in a wild state. 

 Like many other plants which seem to owe their wide distribution to cultivation, rather 

 than other means, this is not found in Australia. 



Cajanus indicus, Linn. 



Cajanus indicus, Linn. ; Miq., Fl. Ind. Bat., i. 1, p. 174 ; Hook, f., Fl. Brit. Ind., ii. p. 217 ; Oliver,

 in Proc. Amer. Acad., vii. p. 164. 



Babar ; Timor Laut. — A monotype, cultivated and wild almost throughout the 

 tropics ; but where it is really indigenous is uncertain. It is not found in Australia, and 

 when Seemann visited the Fijis it only existed there as a garden plant.
