DDrYo, Linn. Durj’on, in the Malay language, is 
the name of the fruit. Linn. 18, Or. 1, Nat. Or. 
Sterculiacex, This tree thrives well in a rich 
loamy soil ; and cuttings, not too ripe, taken oflF at 
a joint, with their leaves entire, will root in sand, 
under a glass, in a moist heat. The fruit of this 
tree is about the size of a man’s head, and is said 
to be the most delicious of all the fruits of India. 
The axil -like substance, which contains the kernel, 
is the eatable part of it, and most resembles cream ; 
yet it is accompanied by such an intolerable stench, 
that, according to Rumphius and Valentyn, it is, 
by law, forbidden to throw them out, near any 
public path, in Amboyna. The smell is said to be 
similar to that of some ptitrid animal substances ; 
yet, all agree, that if the first repugnance is once 
overcome, no fruit is more agreeable than the dvrion. 
The fsuit is also used as ^_b.ait to entrap the ciyci- 
catj hence the specific name.

Echeveria, Decandolle. In honour of M. Echereri,) 
author of the splendid drawings of the Flora Mexi-

succulents, this genus is one of great beauty. E. 
gibbiflora is disposed to grow rather straggling; 
nevertheless, it is worthy of a place in every col- 
lection, on account of its strong, shining loaves, 
and orangy-scarlet flowers. To grow them well, 
they require a soil composed of sandy loam, and a 
little peat, mixed with reduced rubbish of bricks, 
&c. At all seasons they should be cautiously 
w'atered, particularly in winter. They increase 
from cuttings, dried a few days before being put in 
the soil. Synonymes: 1. Cotyledon cwspUosa. 2. C.
