Cultivated in most of the provinces. Distrib. Cosmopolitan in the 

 tropics, probably originally American. 



This is known, Mr. Curtis notes, as Ohie Songnang in the Island of Penang. 

 The large tuberous root, white outside and inside of the appearance and consistence 

 of a turnip, is occasionally, according to Dr. Watt's Dictionary of Economic Products, 

 6-8 feet long and as thick as a man's thigh. It is eaten both cooked and uncooked, 

 is palatable enough but rather insipid. If the rules as to priority of names be 

 rigidly applied this must be known as Cacara erosa Kuntze. 



11. Dolichos Linn. 



Twinino- herbs with stipellate 3-foliolate leaves and minute sub- 

 persistent bracts bracteoles and stipules. Flowers racemose or axillary. 

 OaZ^a:-^w6e campanulate, teeth long or short. Corolla much exserted ; 

 its petals usually equal in length ; keel obtuse or rostrate not spiral. 

 Stamens diadelphous ; anthers uniform. Ovary nearly sessile, many- 

 ovuled; style thickened upwards and bearded down the inner edge or 

 filiform and penicillate round the terminal stigma. Fod flat, linear or 

 oblong, recurved. Species about 20, wide-spread in the tropics of both 

 hemispheres. 



The only species so far reported from the Malay Peninsula belongs to the group 

 Lablab, with a style thickened upwards from a narrow base, bearded down the 

 inner edge. This group is treated by Baker as a subgenus, by Taubert as a section, 

 of Dolichos. De Candolle, Wight & Arnott, and Kurz consider however, with Savi, 

 that it would be preferable to deal with this as the type of a distinct genus Lahldb. 

 Dolichos Lablab Linn. Sp. PL 725. A tall subglabrous wide 

 twining perennial or annual with round smooth or slightly downy stems. 

 Leaves 4-12 in. long, 3-foliolate ; leaflets entire ovate-acute, base cuneate 

 or deltoid, rather pale green, glabrous or slightly pubescent beneath,
