A dull-coloured, inconspicuous little species, allied to B. pachy-

had proved highly satisfactory with him in Sarawak. In the 

 same article there was an editorial note to the effect that Mr. Hose 

 had sent cuttings which would be tried in the Kuala Lumpur 

 Experimental Plantation. In response to an inquiry from Eew 

 the Director of Agriculture, Kuala Lumpur, forwarded specimens 

 for identification. The specimens could not be matched in the 

 Kew herbarium, and as they did not appear to agree with any 

 described species of Dolichos they have been made the type of a 

 new species — D, Hosei — named after the discoverer.

plants as cover crops. His experience demonstrated to him that 

 what was required was a low-growing leguminous plant which 

 could be dug into the soil and which would reproduce itself in 

 time to check the growth of weeds. For three years he had been 

 planting D. Hosei with rubber and had then 200 acres planted 

 with it — the result being that it had '' proved itself in every way 



a success.'' He

almost 



for preference, and in six months after planting should prevent 

 all wash, if planted three feet apart. The trees, he adds, are ring- 

 weeded monthly. It " grows readily from cuttings but seeds 

 are difficult to procure," a fact which has been corroborated during 

 the Kuala Lumpur experiments.
