Pentandria. 
Drosera. Gen. char. — Cal. five cleft, petals five; 
caps, one celled, three valved, superior ; many seeded. 
Dros. Rotundifolia, Round-leaved Sun- dew ; with 
leaves round, radical, stem branched ; perennial ; flow- 
ers in July and August, and is not uncommon in bog- 
gy ground. 
Dros. Longifolia, Long-leaved Sun-dew ; with leaves 
radical, obovate, in similar places with the former, but 
less frequent. 
Dros. Anglica , Great Sun. dew ; has nearly the same 
characters as the preceding, but is furnished with eight 
styles and a fpur-valved capsule, is double the size, 
and a rarer plant. 
The upper surface of the leaves of all these species 
of sun-dew is thinly set with long red hairs, which ex- 
ude a transparent viscid fluid, especially during bright 
sunshine. Small insects, which are attracted to the 
leaves, or alight accidentally upon them, are entangled 
in the hairs, and destroyed by being enclosed in the 
leaves, which fold upon them in consequence of the ir- 
ritation from the motions of the struggling insect. 
Crassula. Gen. char. — Cal. five leaved ; five pe« 
tals ; and five nectariferous scales at the base of the 
germen. 
Cras. Coccinea, Scarlet-flowered Crassula ; with ovate, 
plain, cartilaginous-ciliated leaves, sheathing and unit- 
ed at the base. Native of the Cape, but a splendid 
inmate of the green-house/on account of the fragrance 
and rich scarlet of its flowers, which blow during the 
summer. — Bot. Mag. 495.
