* [t formed part of a collection transmitted by George 
Ure Skinner, Esq. from Honduras, in 1839, to Sir Charles 
Lemon, Bart. M.P. It forms a graceful bush, from two to 
three feet high, but will no doubt attain a much larger size if 
trained against a trellis, and sufficient room allowed for it to 
spread. 
** Stems smooth, round, woody, and branching, about the 
size of a large quill, deep green.  Zeaves fleshy, oblong- 
lanceolate, blunt at the point, from two to three inches long, 
and about an inch wide, tapering to both ends, rounded a 
little at the base, and having large shallow serratures along 
the margin, which are each furnished with a single pale pro- 
jecting hair. Flowers solitary, drooping, of a deep pink 
colour, usually produced at the extremity of the two-years-old 
leaves. Sepals and petals, eight in number, similar in form 
and colour, linear-lanceolate acute, about two inches long,

character of the genus.
