222 ILLUSTRATIONS OF THE BOTANY OF [ Crassulacea. 
common every where. Drymaria (cordata, W.and A.) extensa, belonging to a genus 
which is placed both in this order and in the tribe Alsinee of Caryophyllee (v. p. 78), 
extends from the Peninsula up to the Deyra Doon. The above were the only genera 
known to exist in the plains of India; but J//ecebrum, found in moist places in Europe, 
has a species in Kunawur, which I have called J. erectwm, though it can scarcely be dis- 
tinguished from J. verticillatum; and Herniaria, having the distribution of the order, 
has a species in Cashmere, H. Cashmeriana, nob., nearly allied to H. incana. 
82. CRASSULACEZ. 
The Crassulace@, named also Sempervive and Succulente, are found in various parts 
of the world, but in the greatest numbers north and south of the tropics. From the pecu- 
‘liarity of their absorbing surface, they are enabled to obtain nourishment from the 
driest atmosphere, and probably, to check its excess in the most moist; for we find them 
both within the tropics, and attached to barren rocks in the driest parts of India, as 
of the Cape of Good Hope. Bryophyllum, so remarkable for the rooting property of its 
leaves, introduced from the Moluccas and the south of India, succeeds in the gardens of 
N.India. Kalanchoe, found in Egypt, Arabia, and Sierra Leone, has a species, 
K. varians, in the Deyra Doon and lower hills; with K. laciniata, and two or three 
other species in the Peninsula of India. Sedum and Tillea?, found chiefly in the cold_ 
parts both of the Old and of the New World, and Umbilicus, confined to the former, 
have been discovered in the Himalayas. Of these, the species of Sedum are about 
twenty in number, with flowers of various colours, as red, blue, white, and yellow ; 
some fixed to rocks; others, as S. sinwatum and linearifolium, growing on the moss- 
covered bark of trees; a few are confined in their locality: others spread along the 
whole extent of the mountains with which we are acquainted, ‘as S. Himalayanum, from 
Nepal to Cashmere, and .S. multicaule, rubrum and azureum, if the same as 8. Gerardia- 
num, from the latter to Sirmore and Kemaon. In the arid country of Kunawur, two 
species have been discovered, S. Moorcroftianum, Wall., and S. capitatum, nob. Umbilicus 
spathulatus, nob., Ic. ined. 144. f.1. (Sedum adenotrichum, Wall.”) is common on the 
Mussooree and Suen Ranges, and Tillea? pentandra, Ic. ined. 142, found in the same 
situations, occurs also on Kedarkanta and in Cashmere. 
The Crassulacee, like several other of the families near which they are placed, 
possess little medicinal properties, though a few were included in the older systems of 
Materia Medica.
