at the base, flowers axillary sessile mostly 3-cleft. E. B. 
t. 116. 
On moist, barren, sandy heaths, principally in Norfolk and Suffolk, 
Hants and Dorsetshire. ©. 6, 7. — A minute succulent plant, 
scarcely 2 inches high, with small, reddish, opposite, oblong, blunt 
leaves. Cal. leaves mostly 3, bristle-pointed. Petals very small, al- 
most subulate, white or tipped with rose-colour. 
2. Cotyledon Linn. Pennywort. 
Cal. 5-partite. Pet. united into a tubular or campanulate 
corolla. Siam. 10, inserted upon the tube of the corolla. Fol- 
licles many-seeded, each with a scale at its base. — Named from 
kotu\t], a cup ; to which the leaves of some of the species may 
bear a distant resemblance. 
1. C. Umbilicus Huds. ( Wall P.) ; leaves peltate crenate 
depressed in the centre, stem with a (usually) simple raceme of 
pendulous flowers, upper bracteas minute entire, corolla scarcely 
cleft to the middle, lobes ovate acute erect, root tuberous. 
E. B. t. 325. 
Rocks, walls, and old buildings, especially in subalpine countries. 
%. 6 — 8. — Whole plant succulent. Stem from 6 inches to a foot 
high. Leaves mostly radical. Flowers cylindrical, yellowish-green. 
[C. lutea Huds., E. B. t. 1522, having erect flowers, patulous 
narrow and acuminated lobes to the corolla, and toothed bracteas, is 
from Portugal, and must have been introduced into the British Flora 
by mistake. It is by no means a hardy garden-plant.] 
3. Semtervivum Linn. House-leek. 
Cal. 6 — 20-cleft. Pet. distinct, or slightly united at the base. 
Stum, twice as many as the petals, or as many and opposite to 
them. Follicles many-seeded ; hypogynous scales laciniate, 
toothed or none. — Name derived from semper , always , and 
vivo, to live ; on account of its tenacity of life. 
1. S. * tectdrum L. ( common H.) ; leaves ciliate, off-sets 
spreading, petals about 12 entire and hairy at the margins. 
E. B. t. 1320. 
House-tops and on walls. If. 7. — The /lowers of this well-known 
and rustic medicinal but unquestionably not indigenous plant are no 
less beautiful than they are curious in their structure. The number 
of stamens is in reality twice as many as the petals; of which those 
opposite to the petals are perfect ; the rest alternating, are small and 
abortive. 
4. Sedcm Linn. Orpine and Stonecrop. 
Cal. in 4 — 6 deep segments, often resembling the leaves. 
Pet. 4 — 6, distinct, patent. Stam. 8 — 12. Follicles many-
