 getting a little firm, in sandy soil, with a bell-glass 

 in summer ; sandy peat and fibry loam. Winter

The South American species possess much of the 

 qualities of, and are substituted for, Ipecacuanha. 

 Herbaceous plants, flowering in June, by division 

 and seed ; under-shrubs, by cuttings in sand, 

 under a bell-glass ; peat and loam. All the fol- 

 lowing require greenhouse culture, except stri'c- 

 tum, which is a stove plant.

 1-Monogynia.) 



Annuals, by seed in a hotbed ; perennials, by 

 seed and cuttings of the short side-shoots, in 

 sandy peat, under a bell-glass, and in a good 

 bottom-heat; bulbous and tuberous, by division, 

 and by cuttings of the young shoots, as they 

 com ence growing; the bulbs and tuberous 

 ones, especially the hardier ones, are used for hcr- 

 bn-eous grafting, merely making a cleft, and slip- 

 shoot into the place, claying over, 



ring the young s 

 ind plunging in 



and plunging in a hotbed ; stout, short stems, 

 with roots of Sello'ivii, are frequently used for 

 grafting the more tender sorts; peat and loam. 

 T mp. for stove kinds, 60 to 85 in summer ; 50 

 to 60 in winter. The crimson Horsfa'Uice requires 

 a good heat.
