OTHEE SPECIES OF SEDUM. 
These are so very numerous, that I can only give a few of the most remarkable. 
S. AIZOON, Lin. 
The Yellow Orpine. A native of Siberia, introduced in 1757. 
S. SPHERICUM, Bieb.; Bol. Mag. t.WlO. 
A very beautiful little plant, very unlike a Serlum, with bright pink flowers. A native of Caucasus, 
introduced in 1822. 
S. 0PP0S1TIF0LIUM, Sims; Bot. Ma^. t. 1807. 
A very handsome species, with white flowers and toothed leaves. Its native country and year of introduction 
are unknown. 
S. POPULIFOLIUM, Lin.: Bot. Mag. t. 211. 
This is the only hardy Sedum with a shrubby stalk. It is a native of Siberia, whence it was introduced 
in 1780. 
S. ANACAMPSEROS, Lin. ; Bot. Mag. t. 118. 
The' Evergreen Orpine. A very singular plant; a native of the south of France, introduced before 1597. 
The leaves are glaucous, and the flowers pink. 
All the Sedums may be propagated by cuttings, or by dividing the roots in autumn, as they very rarely 
ripen seed. 
CHAPTER XXII. 
SAXIFRAGACE.E, 
Style none ; etigmas sessile on the tips of tlie lobes of tlie ovary. 
Scads numerous, very minute. 
CniaiCTEa of the Ohder. — Calyx either superior or inferior, 4 or 
5-lobed. Petals five, or wanting, inserted between the lobes of the 
calyx. Stamens 5 — 10. Ovary consisting of two or five carpels. 
Description, &c. — The most popular genera in this order are Hydrangea and Saxifraga ; the former, 
however, contains only shrubs, and is therefore unsuitable to the present work. The genus Saxifraga is a very 
extensive one, and though it has been divided by several authors, the new genera which have been formed from it 
do not seem likely to be generally adopted. The name Saxifraga signifies "break-stone," in allusion to the 
medicinal properties of some of the species. 
GENUS I. 
SAXIFRAGA, Lin. THE SAXIFRAGE. 
Lin. Syst. DECANDRIA DIGYNIA. 
Generic CniRicTER. — Calyx cither superior or inferior, of four or five 
sepals, which cohere more or less at their base. Petals five or wanting, 
inserted between the lobes of the calyx. Stamens 5 — 10, inserted 
either into the calyx or beneath the ovarium ; therefore they are either 
perigynous or hypogynous ; anthers 2-celled, bursting lengthwise. 
Disk either hypogynous or perigynous, sometimes obsolete, sometimes 
annular and notched, rarely consisting of five scales. Ovarium inferior, 
or nearly superior, usually consisting of two or five carpels or follicles, 
cohering more or less on the inner side, but distinct at the apex ; 
sometimes 2.celled, with a central placenta ; sometimes 1 -celled, with 
parietal placentas, rarely 4 — 5-celled. Styles none; stigmas sessile 
on the tips of the lobes of the ovarium. (G. Don.) 
Description, &c. — Perennial plants, with thick woody roots, and large fleshy leaves. The flowers are 
showy, and they are generally disposed in thyrsoid panicles.
