Shrubby Dolichos. Shrub. 



Cult. None of the species are worth cultivating for orna- 

 ment except the D. ligmisus, D. Jccijiitni, and D. Curtisii. 

 A light rich soil answers all the species, and they are either in- 

 creased by seeds or cuttings ; cuttings planted in a pot of sand 

 root freely, those of the stove species require heat.

 root freely if planted in a pot of sand placed under a hand-glass, 

 in heat.
