A very beautiful species not yet reported from the Malay Peninsula proper and 

 not recorded by Prof. Miquel from the Malay Archipelago. It may, however, be 

 found if looked for in the sea-fences of screw-pines along the coasts, this being the 

 habitat chiefly affected by it in the Andaman group.

Andamans ; an introduced weed. Distrib. Northern Africa, S.-E. 

 Asia, Malay Archipelago. 



An annual crop and a perennial weed throughout its natural area. The 

 perennial form has usually more deeply lobed leaflets ; in the annual form lobed 

 and entire leaflets are generally met with in varying proportions on the same plant. 

 Though not as yet recorded from the Malay Peninsula proper, it may be expected to 

 occur there as an introduced weed. 



4. Phaseolus calcaratos Uoxb. Hort. Beng. 54. A twining annual, 

 or perennial with annual pubescent rarely glabrous stems 6-10 feet long,
