ments awl-shaped, compressed below, and pubescent on the 
inner side near the base. 
53. Sedum PForsterianum.— Little Ormeshead.—June, 1828. 
—Segments of thecalyz very seldom elliptical and obtuse. I find 
them generally broadly ovate, bluntish, flat, or with the sides 
sometimes slightly reflexed, and like the flower-stalks, glau- 
cous. Petals four times as long, lanceolate, bluntish, keeled. 
Filaments as long as the petalé subulate, somewhat flattened 
below. Germens lanceolate, tapering. Stigmas indistinct. 
Nectaries oblong, slightly notched, flattened, broader at the 
base than at the abrupt summit, one at the base of each ger- 
men, opposite the petals. Stem-leaves mostly erect, acute, 
fleshy, the upper ones rather flattened, and all of a dark 
purplish-green colour.—Perhaps the compact, hemispherical 
or round-topped cyme, is the best mark by which to distin- 
guish it from S. reflexum. 
54. Cerastium vulgatum.—May 15, 1827.—Petals cloven, 
but not very deeply so. Five stamens longer than the rest, 
alternate with the petals and glandular at the base. 
55. Cerastium semidecandrum.—April 25, and May 15, 1827. 
— In some situations the plant is entirely procumbent; some- 
times upright.—Stems constantly branched.  Calyz-leaves 
acute, otherwise corresponding with Eng. Fl. Petals striated 
or furrowed. Each of the filaments seems to have a nectary 
at its base.—Hugh Davies appears to have been but ill 
acquainted with the plant, he having noticed the most com- 
mon appearance as a singularity, under the name of Cerastium 
humile.—v. Dav. Wel. Bot. | 
56. Cerastium alpinum.—Craig Calleach. nt uly 13, 18271, — 
On comparing this with Welsh specimens of C. latifolium, I 
can find no essential difference in the parts of fructification. 
They differ in habit. C. alpinum has the stem, 1 think 
invariably, simple, erect, with fewer leaves than in latifolium, 
the upper pairs of leaves very distantly placed. The anthers, 
pollen, filaments, stigmas, petals, calyx, and — are -y 
similar in these two species. 
57. Cerastium latifolium.— Snowdon.— August 7, 1828.— 
Petals with 5 or" strong, prominent ribs at the base, subdivided
