24 S. TECTÒRUM (Lin. spec. p. 664.) leaves ciliated; offsets 
spreading ; petals 5-9, spreading ; scales of flowers cuneiform, 
carunculate. 2. H. Native of Europe, on rocks and roofs of 
houses; also in many parts of Britain, on walls and cottage 
roofs, but perhaps not properly indigenous. D. C. pl. grass. t.

529. Flowers purplish. Stamens sometimes changed into car- 
pels according to Pet. Thouars, in bull. phil. nov. 1807. The 
Juice of the common house-leek either applied by itself, or mixed 
with cream, gives present relief in burns, and other external in- 
flammations ; it is also said to cure corns. With honey it is a 
useful application in the thrush. Boerhaave found 10 ounces of 
the juice beneficial in dysenteries, and others have found it use- 
ful in gonorrhceas ; but it is not admitted into modern practice. 
The house-leek had several names formerly, as sengreen and 
aygreen, both translations of Sempervivum. It has also been 
called jupiter’s eye, bullock’s eye, and jupiter’s beard. In Ger- 
man it is called hauswurz; in French la grande joubarbe, and in 
Italian sempervivo maggiore. 
Roof or Common House-leek. Fl. June, Sept. Britain. 
Pl. 1 foot. 
25 S. FLAGELLIFÓRME (Fisch. in Link, enum. 2. p. 20.) leaves 
ovate, mucronate, papillose, with papillously ciliated margins ; 
offsets spreading, lateral; branches of cyme bifid. Y.H. Na- 
tive of Siberia. Allied to S. montdnum, but differs in being 
larger, and in the offsets being at the ends of long flagella. The 
leaves of the offsets terminate in a stiff brown point ; cauline 
leaves narrower. Corolla reddish. 
Flagelliform Houseleek. FI. July, Aug. Clit. 1823, 
4 to 2 foot. 
26 S. monta‘num (Lin. spec. p. 665.) leaves of the offsets 
obovate-oblong, shortly acuminated, beset with glandular pubes- 
cence on both surfaces, obsoletely ciliated, entire, pubes- 
cent; offsets rather contracted ; flowers rotate ; petals 10-14, 
lanceolate, acuminated, spreading, 3 times longer than the calyx, 
scales of flowers small, nearly quite entire; style discoloured at 
the apex. 2. H. Native of the Pyrenees and the Alps of Eu- 
rope, &c. on rocks. D. C. pl. grass. t. 105. Jacq. fl. aust. 5. 
append. t. 41. Flowers deep red. This species differs from S. 
tectòrum in the smaller stature, and in the nectariferous scales 
being almost wanting ; and from S. arachnoideum in the absence 
of the cobwebbed wool. Scales of flower square and retuse.

petals 12, hairy. 2.H. Native of Caucasus, at the torrent of 
Pi. 
XIX. Sempervivum. 
Terek, on rocks. Flowers red. Very like S. arachnoideum, but 
differs in the hairs on the leaves being distinct, not cobwebbed, 
Dwarf House-leek. Fl. June, July. Cit. 1824. Pl. $ foot. 
30 S. TENUIFÒLIUM (Smith, fl. graec. prod. 1. p. 335. fl. gree, 
t. 474.) leaves subulate: lower ones dilated at the base, and 
sheathing ; cauline ones adnate, sessile, prolonged at the base; 
flowers with 7-10 styles; offsets cylindrical. %. H. Native 
of Calabria, on arid hills. Sédum rostratum, Ten. fl. nap. prim.

carinatum, Link. Sempervivum anémalum, Lag. ex Spreng. 
Petals yellow. More the habit of a Sedum than a Sempervivum, 
and has much the habit of Sedum rupéstre. 
Fine-leaved House-leek. PI. + foot. 
Secr. III. Mona’ntues (from povoc, monos, one, and avoc, 
anthos, a flower ; flowers one on each peduncle). Haw. rev. suce, 
p. 68. D.C. prod. 3. p. 414. Real offsets none. Leaves clavate, 
crowded in a somewhat rosulate manner. Flowers purple. 
Glands large, orbicularly cochleate, serrulated when examined 
through a lens, one-half shorter than the petals, but 4 times 
broader, and rufous. Haw.—A very small nearly stemless 
herb. 
31 S. mona’ntuEs (Ait. hort. kew. ed. 1. vol. 2. p. 149.) 
leaves terete, clavated, glabrous, crowded in a rosulate manner; 
peduncles naked, generally 1-flowered, rarely few-flowered ; 
petals 6-9, hardly longer than the calyx ; scales of flower obcor- 
date. 2%.D.G. Native of the Canary Islands. Curt. bot, 
mag. t. 93. D.C. pl. grass. t. 157. Monánthes polyphýlla,

or 2 inches. 
+ Species hardly known. 
32 S. Arrica‘num (Mill. dict. ed. 8. no. 7.) margins of leaves 
serrately toothed; offsets spreading. %. D. G. Native of the 
Cape of Good Hope. Haw. syn. p. 367. This species has 
never been seen except by Miller; it is therefore doubtful. 
Sprengel says it is the same as S. arbdreum. 
African House-leek. Clt. 1768. Shrub. 
33 S.? Srcuie'r1 (D.C. prod. 3. p. 414.) stem herbaceous,

stellàtum, Poll. fl. ver. 2. p- 114. exclusive of the synonyme 0 
Smith. Itis probably a variety of Sèdum dasyphýllum, but the 
flowers are said to be yellow. The plant is therefore very 
doubtful. 
Seguier’s House-leek. Pl. 4 foot? 
34 S.? Hispa’yicum (Willd. enum. p. 508.) leaves subulate, 
semi-terete, ciliated, imbricated ; cymes bifid. Y. H. Native 
of Spain. The rest unknown. Perhaps a species of Sedum.

Cult. The greenhouse kinds of house-leek are chiefly natives 
of the Canary Islands. A mixture of sand, loam, and brick-rub- 
bish is a good soil for them; and care must be taken not to givé 
them too much water when not in flower. Cuttings taken off A 
plants, and laid to dry a few days, will strike root freely without 
any covering of glass. Cuttings of some species are difficult to 
obtain, such as of S. tabulifórme, &c. ; the best way in such = 
is to cut the top out, and lateral shoots will be immediateY 
produced. The hardy kinds are well fitted for rock-work, 0% 
to grow on walls; and they are easily increased by the offsets, 
which are issued in great abundance. A light soil suits them 
best.
