linear, scale-formed, reflexed.—Native of Spain, on the rocks 
called Borrequillos, in Sierra Nevada. Perhaps a species of 
Sempervivum, ex Bory. ann. gen. 3. (1820.) p. 14. The rest

Cult. The greater part of the species being quite hardy, and 
all succulent, they therefore succeed best on rock-work, for which 
they are well adapted. Some of the rarer kinds may be grown 
in small pots. They succeed best in light, sandy soil, or one com- 
posed of loam and brick rubbish. All are readily increased 
by cuttings. The seeds of the annual species only require to 
be sown on rockwork. There are a few of the species marked 
greenhouse; these will require the same treatment as that re- 
commended for the species of Globilea, see p. 106.

Carpels equal in number to the petals.—Herbs sometimes stem- 
less, with young plants rising from the axils; or caulescent, 
without any young plants; or shrubby and fleshy. Leaves 
usually revolute. Branches of cymes sometimes disposed into 
a corymb, and sometimes into a panicle. Petals yellow, white, 
or purplish.
