 and as they are creeping plants, they are easily increased by 

 dividing.

 plant differs from Dolichos in the calyx being 4-cleft, and from

Soft Dioclea. Fl. July. Clt. 1824. Shrub tw. 



Cult. The species of this genus will grow well in light rich 

 soil, and they are easily increased by cuttings planted in sand, 

 with a hand-glass placed over them, in heat.

 the banks of rivulets in Madagascar by M. Aubert Du Petit 

 Thours. The plant is cultivated in the Mauritius for the sake 

 of its seeds, which are used in the same way as we do peas.
