ARISTOLOCHIA (from aristos, best, and locheia,

genus of stove, greenhouse, or hardy, evergreen or deci- 
duous, climbing or erect shrubs. Flowers axillary, clus- 
tered, or solitary, pendulous, of most extraordinary forms; 
perianth tubular, curved, or straight, with an oblique, 
cordate limb; stamens six, rarely four, or numerous, ad- 
hering to the stigma; capsule six-valved. Leaves cordate - 
entire or lobed. Good loam, with a small proportion of 
decayed manure and a slight addition of sharp sand to 
secure efficient drainage, is a good compost for the whole. 
They will thrive when- planted out in the conservatory 
more satisfactorily than elsewhere; for as they usually 
grow a considerable height before flowering, they require 
very long trellises in pots, and have to be trained up and 
down; or, better still, round a pillar of uniform cir- 
cumference, a pyramid form being useless. The best way 
is to train them round, close down to the pot, and keep 
on about 2in. from one turn to the next. Some of the 
larger sorts will require more room. Cuttings root freely 
in sand under a bell glass with bottom heat.
