Cult. For the culture and propagation of the annual species 

 of this genus, see Microcodon, p. 737. The frame and green- 

 house perennial and shrubby species, as Lightfootia, p. 735. 

 The hardy perennial species should be grown in pots, in a mix- 

 ture of peat and loam, and kept rather moist; and they are easily 

 increased by division.
