but the tubers must be carefully looked after in the winter or 

 after the plant dies down, and not be allowed to get too dry or 

 too wet.

Holstii (fig. " Engl. Bot. Jahrb." xviii. t. 4, 5).— Tropical East 

 Africa. A pretty, delicate, erect-branched stove plant ; flowers 

 bright blue ; stems succulent, dark purple, "Bot. Mag." 8150. 



Kirkii (fig. " Bot. Mag." 6782).— Tropical East Africa. Small 

 stove species ; fleshy stems ; flowers small lilac, in axillary loose 

 cymes ; a pretty, small pot plant. 



parviflorus (fig. " Bot. Mag." 7036).— South Africa. A green- 

 house species ; leaves radical ; scapes 6-10 inches high, racemose ; 

 flowers -| inch long, slightly recurved, white and violet.

 plant. 



Rexii (fig. " Bot. Mag." 3005).—" Bot. Reg." 1173. South Africa. 

 A well-known species, but improved out of existence by the 

 hybrids. Nearly all the garden hybrids raised so largely in 

 nearly all nurseries and in many private establishments are 

 off this species and its hybrids crossed with Dunnii, Saunder- 

 sonii, Wendla?idii, polyanthus, and others ; they are too numerous 

 and well known to require much notice here. They are very 

 useful aud beautiful plants ; they should be raised every January 

 or February from seed, as the old plants should seldom be kept 

 for more than two years ; they require a shaded situation in a 

 greenhouse and plenty of water when growing ; except when 

 young difficult to keep in health through the winter. Achemeni- 

 flora and grata are particularly good hybrids, raised at Veitch's. 



The following are large, rather ungainly species, more adapted 

 for botanical than private gardens : — Dunnii (fig. " Bot. Mag." 

 6903). Transvaal. Large leaves, reddish flowers ; grandis 

 (fig. "Bot. Mag." 8042). South Africa, a large species, large
