FURCR^A 



except that the Furcrieas are given more heat and water. 

 F. r/igantea has a very pretty variegated form, which 

 makes a useful pot-plant. 



As a rule, Furcreeas bear fruit not more than once, and 

 then die without producing suckers. However, they 

 produce while in flower an immense number of bulbels, 

 which may be used for propagation. It is impossible to 

 say at what size or age the plants will bloom. Grown 

 in pots, they may take a century. On the other hand, 

 plants from bulbels have been known to flower at 3 years.

 This and F. gigantea are widely spread in trop. Amer.

 in cult. All the rest are rare. Var. in^rmis, Baker, is

pub6scens, Todaro. Baker does not say that the lvs. 

 are not convolute at the tip, nor does he distinguish the 

 lvs. from those of F. Vnttensis, except in the smaller-

 Furcra?a proper with a pubescent ovary. Peduncle 

 scarcely longer than the lvs.: panicle 5 times as long as 

 the peduncle ; branches copiously compound. Trop.
