1 D. replans. 2 D. orbiculatum. 3 D. recurvatum. 4 D. 

 divergens. 5 D. purpurewn. 6 D. cephalotes. 7 D. patens. 

 8 D. tuberosum. 9 D.quinquangulatum. 10 D. arbbreurn. 



Cult. The stove and greenhouse species of this genus grow 

 well in a mixture of loam and peat, and young cuttings will root 

 readily in sand, under a hand-glass in heat. The hardy kinds 

 or those natives of North America succeed well in a light rich 

 soil, and are increased by dividing at the root in spring, or by seeds.
