Cult. This is a genus of fine broad-leaved trees. They will 
thrive well in a mixture of loam, sand, and peat, and cuttings, 
not deprived of their leaves, will root readily in sand, under a 
hand-glass, in a moderate heat.

Lime-tree-leaved Astrapæa. Clt. 1824. Tree 10 feet? 
Cult. A. Wallichii is one of the finest plants that ever was 
introduced into Britain; when in flower nothing can exceed it 
in beauty. All the species will grow well in a rich soil or a 
mixture of loam and peat; and young cuttings planted in 
mould, and placed under a hand-glass in heat, will soon strike 
root. 
+ Uncertain Dombeyacee.
