Eastern India, Burma, and Cochin China. 
This is a very puzzling plant, and we alternately took it to be 
the same as the Indian and a new species, on account of the 
dimorphic corolla. In the plate cited above the middle lobe of 
the lower lip is very narrow and. tongue-like, and the first 
flowers we dissected of the Chinese plant had an almost equally 
three-lobed lower lip with rouuded lobes; and the upper lip or 
galea of the corolla has a distinct thickened lobe on each side 
below the middle. On examining other flowers we found some 
with the lower lip like that figured, and we suspect that these 
may be sexual differences, for flowers with this kind of lip seem 
to be invariably sterile. There are nearly ripe nutlets in the 
Chinese specimens of a dark brown colour, very minutely pube- 
rulous or glabrous, oblong and subtrigonous, with a very small 
basal scar. The fruiting-calyx is enlarged, rigid, nearly or quite 
glabrous, and transversely nerved. 
This is the plaut referred to in the ‘Kew Bulletin, 1888, 
p. 74, in connection with Patchouli.
