Tephrosia Vogelii, Hooh. f\ 



This is a useful species, but not of so iniicli value as the ones 

 already nientionecL 



Desmodium gyroides, DC, 



(Potang koedjang bodas). 



This plant is the most valuable of the many species of 

 Desmodium known to us at present. It grows in bushy form 

 and produces many leaves; it can also be cut to any height^ and 

 lives a long lime. Z>. gyroides is to be found in the neigh- 

 bourhood of Plaboean-ratoe, up to 2500 feet. It produces^ a 

 quantity of seed, which is very small, and it is therefore advis- 

 able to sow it in lines. The seed will germinate in about a 

 fortnight. One drawback to the use of this plant, however, is 

 til at often many of tlie young plants die shortly after they appear 

 above the ground for some reason which has not yet been satis- 

 factorily explained. 



This Desmodium is considered to be a very good manurial 

 plant for Coffee and Hevea plantations, since it produces 

 numerous leaves, which form a fairly thick humus layer. It does 

 not suffer from any disease; the only fault to be foimd with it is, 

 that some of the plants, after being pruned a couple of times, 

 may be attacked by Corticium sahnonicolor. If the injured 

 plants be removed immediately, however, there is no fear of any 

 harm being done to the cultivated plants. 



Indigofera Anil, Linn. 



m 



This plant is of a bushy habit. The seed is very sniall, and 

 is sown in lines eighteen inches to two feet apart; it will ger- 

 minate in about seven to liine days. When first the seedlings 



amone^st thei 



month to a mon 

 weeds becomes s 



be identified. The plantation will be covered with a dense 



6 



and 



months 



The plant lives about two-aud-a-half years. 



Another Indigofera (/. hirsuta) has also been tried, but it 

 does not live so long as /. Anil^ and as it can only be cut once 

 it has not proved as useful as that species.
