72 THE PINK FAMILY. 
The nearly glabrous form, which is the C. alpinum of most Continental 
botanists, is not so common in Britain as the woolly one, the C. lanatum 
of some foreign botanists. These two were formerly distinguished by 
British botanists as C. alpinum and C. latifolium, but the latter name is 
now generally given to a variety with a shorter pubescence, and usually 
with a shorter and broader capsule and larger seeds, but these differences 
often appear quite inappreciable. The C. latifolium, Linn. ? of the Alps of 
central Europe is not British. [A Cerastiwm occurs in the Shetland 
Isles, C. nigrescens, Edmonstone, which has seeds larger than those of C. 
alpinum, covered with a loose testa as in true latifolium. It is the 
alpinum, var. Edmonstoner, of Mr. N. E. Brown. ] 
4. C. trigynum, Vill. (fig. 163). Starwort C.—Stems shortly per- 
ennial, prostrate and intricately branched, but much more slender than 
in C. alpinum ; the whole plant glabrous, except minute hairs down one 
side of the branches, or rarely generally hairy. Leaves narrow, usually 
curved to one side. Flowering branches shortly ascending, with 1 or 2 
large flowers, on rather long peduncles, as in C. alpinum ; but the styles 
are 8, very seldom 6, 4, or even 5, the teeth of the capsule always double 
the number of the styles. 
In moist, alpine situations, in Europe and Russian Asia to the Arctic 
Circle. Frequent in the Breadalbane range in Scotland, and other 
mountains to the northward. Near Bantryin Jreland. Fl. summer. 
X. STELLARIA. STARWORT. 
Annuals or perennials, generally more glabrous than Cerastium, the 
leaves usually pointed and often cordate, the sepals more pointed and less 
distinctly scarious at the edge. Sepals5. Petals 5, deeplybifid. Stamens 
10, occasionally reduced to 5 or fewer. Styles 3, or rarely 5. Capsule 
opening to the middle, or lower down in as many or twice as many valves. 
A large genus, extending over nearly the whole geographical range of 
the family, and generally a natural one, although some species, especially 
S. media and S. uliginosa, resemble Arcnaria trinervis, and can only be 
distinguished by a close inspection of the minute petals and capsules. 
Most of the species are occasionally, though rarely, apetalous. 
Lower leaves stalked, ovate or heart-shaped. 
Petals much longer than the calyx. 
Five styles in most of the flowers . : : . 1. S. aquatica. 
Three styles . 2S. nemorum. 
Petals shorter or scarcely longer than the calyx. 
Lower leaves ovate, cordate, on long stalks . 3. S. media. 
All the leaves narrowed at the base, sessile or shor tly ‘stalked . 4. 8. uliginosa. 
All the leaves narrow-lanceolate or linear, and sessile or nearly sO. 
Petals shorter or scarcely longer than the calyx. 
Plant annual. Leaves oblong or lanceolate, short . ; . 4.8. uliginosa. 
Stock perennial. Leaves narrow-lanceolate or linear . 5. S. graminea. 
Petals considerably longer than the calyx. 
Leaves very narrow. Sepals distinctly 3-nerved . 6. S. glauca. 
Leaves lanceolate or linear-lanceolate. Nerves of the sepals 
scarcely perceptible . ; F . 7. 8. Holostea. 
1. S. aquatica, Scop. (fig. 164). ‘Wa Po i A ont with much 
of the habit and the heart-shaped leaves of S. nemorum, but on a rather 
larger scale, usually more pubescent, and slightly viscid, the flowers 
smaller, and always known by all or most of them having 5 styles, and
