Stem one and a half to two feet in height, erect, branched from the axils of 
the leaves, particularly near the base, terete, of a purple-brown colour, 
slightly pubescent or hairy above. Leaves numerous but distant, oppo- 
site and connate at the base, lanceolate, patent and recurved, acute, at- 
tenuated at the base into a short kind of footstalk, the margin acutely 
and distantly unequally serrated or dentato- serrate, distinctly veined and 
wrinkled, beneath having the veins prominent ; the whole of the leaves 
are glabrous, except in the young leaves, where a decided pubescence is 
visible on the under side : the colour a yellowish-green. 
Flowers placed in large, handsome panicles, at the extremity of the stems, 
the panicle di- or trichotomous in its ramification, the ultimate branch- 
let, however, being subumbellate. Bracteas placed in pairs at the base 
of each division of the panicle, the lowermost ones scarcely differing from 
the leaves but in being shorter and broader, the upper ones gradually 
smaller and more cordate. 
Calyx of four green, spreading, broadly ovate obtuse leaves, glabrous or 
very minutely ciliated at the margin, veined. Corolla of a fine deep yel- 
low, large and glabrous, slipper-shaped ; the upper lip remarkably short, 
the lower one large, globose, with the sides and extremity singularly in- 
volute and hidden within the cavity, the whole curved upwards so as to 
cover the upper lip, and almost wholly concealing it. Stamens placed 
upon a raised margin at the base and within the upper lip of the corolla ; 
Filaments short, subulate. Anther white, of two oblong lobes, placed end 
to end, and deflexed before bursting, and white, afterwards rising up«.
