DESCRIPTION. 
Root consisting of numerous ovate tubers, with many fibres, biennial; leaves radical, lanceolate, undulate, 
intire, 4—6 inches long, 14 broad, longitudinally nerved, smooth on both sides, paler beneath, decurrent, and 
keeled at the base; spike rising in the centre of the leaves, from a lanceolate bracte, that incloses the whole 
fascicle, an inner bracte accompanying each flower; calyx superior, of one leaf, sheathing the tube of the corolla 
nearly half its length, and opening obliquely on one side; corolla tubular, with a double border; outer limb of 
three long, narrow, linear-lanceolate segments, pure white; inner limb of three segments, two of which are equal, 
erect, ovate, intire, white; the lower segment or lip larger than the others, bilobate, of a deep purple or violet 
colour, with a white claw; filament extending beyond the anther, and terminating in a bifid crest; anther in two 
lobes, embracing the style; style filiform, supported at the base by two subulate processes about a quarter of an 
inch long; stigma funnel-shaped, margin simple. 
OBSERVATIONS. 
This small but elegant species of Keempferia, (or as Profes. Sprengel has of late denominated it, Kamprrna,) 
is a native of Bengal, flowering during the rainy season, and was introduced into the Royal Garden at Kew by. 
Sir Joseph Banks, in 1797. It generally flowers in this climate early in the spring. The root, which like those 
of the other species, is strongly aromatic, is used by the natives of the East as a remedy for a cough, for which 
purpose a small part of it is mixed up with their betle. (Rowb. in As. Res. xi. 328.)
