This plant grows in the open air in Kew Gardens to the height 
of 12 or 18 inches, its numerous stems being annually deci- 
duous: it is altogether covered with short viscous pubescence, 
which, as well as the foliage, is of a dark fuscous hue, becoming 
ereener after the fall of the flowers. The leaves are 23 mehes 
long, 14 inch broad, upon a fleshy channeled petiole of 1 meh in 
length, the nervures and stem being of a purplish hue: the calyx 
is 3 lines long, the corolla 6 lines, the stamens and style bemg 
exserted to a length of 3 lines: the capsule is 3 lines in diameter, 
inclosed in the calyx of equal diameter, and of nearly double 
its length, which is pilose, reticulate, submembranaceous, and 
in no degree swelling in the middle: the lower valve of the cap- 
sule is somewhat membranaceous, greenish, and marked with 
several longitudinal nervures ; the operculum, crowned by the 
persistent base of the style, is of a blackish violet hue, soft, of 
thin texture, and quickly shrivels up in drying: the seeds are few, 
proportionately rather large, yellowish brown, scrobiculated, oval, 
reniform and compressed : the embryo is arched in a semicircular 
form ; the radicle, about the length of the cotyledons, points to 
the basal angle below the lateral hilum.
