The root is long, slender, knotty and fibrous ; the leaves are 
deeply serrated, and are placed upon long, slender footstalks, 
which stand in pairs ; sepals five, persistent, more or less unequal ; 
with an imbricated aestivation ; petals five, seldom four, in conse- 
quence of one being abortive ; the stamens usually monadelphous, 
hypogynous, two or'three times as large as the petals, some occa- 
sionally abortive ; ovarium composed of five pieces placed round 
an elevated axis, each one-celled, one-seeded ; ovula pendulous ; 
styles five, cohering round the elongated axis; formed of five 
pieces, cohering round a lengthened, indurated axis; each piece con- 
sisting of one cell, containing one seed, having a membranous per- 
icarpium, and terminated by an indurated style, which finally curls 
back from the base upwards, carrying the pericarpium along with 
it ; the seeds are solitary, pendulous, and without albumen ; the 
embryo is somewhat curved ; the radicle is usually found pointing 
to the base of the cell ; the cotyledons are foliaceous, convolute, 
and plaited ; stems turned, and separate at the joints; leaves either 
opposite or alternate ; in the latter case opposite the peduncles. 
For this beautiful species of the Geranium tribe, we are 
indebted to Mr. Carter, an artist of great merit. His spe-
