382 MR. D. MORRIS ON THE PLANTS 
The typical plant (fig. 1), described by Lamarck and figured by 
Cavanilles, is an erect shrub or small tree, with oval pointed 
leaves, dark green above, pale beneath, and marked with a charac- 
teristie areolation. Besides those already quoted, figures repre- 
senting the type are given in Le Maout and Decaisne's ‘ Traité de 
l. Flower. 2. Ovary and stigmas. 3. Fruit. 
Botanique, p. 321, and in Baillon’s * Hist. des Plantes,’ v. figs. 
80-87. Specimens are in the Kew Herbarium from Mathews, no. 
2028, from Pearce, and from MeLean, all collected in Peru. 
Plants are cultivated in the Botanie Gardens of Ceylon and 
British Guiana, and at the Jardin des Plantes, Paris. 
The leaves of typical plants become dark green, or even brown, 
in drying. It has been shown by an interesting series of chemical 
analyses just concluded by Mr. Alfred G. Howard, F.C.S., F.LS., 
with Coca-leaves received at Kew, that leaves of the type contain 
a high percentage (660) of erystallizable cocaine, with little, if 
any, unerystallizable cocaine.
