GESNERIACE/E. XXII. Dinymocarrus. 
acutely toothed, and with two pairs of others at the top of the 
stem, which are crowded, ovate, acutely toothed ; peduncles 2-8, 
terminal, twice or thrice dichotomous or trichotomous ; central 
pedicels twin, or solitary: terminal ones by threes. 2. G. 
Native of Nipaul and Kamaon, on rocks and trunks of trees. 
Plant pubescent. Bracteas or involucels cordate under each 
division of the peduncles. Calyx campanulate, fleshy, bluntly 5- 
toothed. Corollas purple. This species yields an aromatic 
drug, which is in high repute among the Hindoos, especially 
their ladies, who use it as a perfume. It is called Kumkuma, 
also Rani-Goindhi, and consists of the dried primordial leaves, 
which are wrinkled, small ovate, covered with dense silvery, 
soft hairs, intermixed with numerous brown, resinous dots. 
When rubbed between the fingers they assume a reddish tinge. 
Their fragrance is of a very delightful kind, and continues long 
after they have been dried. "The leaves of all the species pos- 
sess in a greater or less degree a peculiar fragrance, which is 
elicited by rubbing the green parts, but is entirely lost in the 
dried state, except in the present species.
