flowers.” Torr. and Gr. Capsule large, roundish, with few large, 
and black seeds. The American H. oblongifolia is no longer consi-

Flowers all perfect. Sepals 5. Pet. 5, conspicuous, undi- 
vided. Stam. 10, or occasionally 5. Styles 3 — 4. Caps. 1- 
celled, opening with 3 — 5 entire valves (alternating with the 
sepals when as many), or with 6 — 10 valves (or teeth). Seeds 
many, minute. — Named from arena , sand, the greater number 
of species growing in sandy soil. 
§ 1 . Valves of capsule as many as the styles, entire. Alsine. 
1. A. verna L. ( vernal S .); stems numerous panicled above, 
leaves subulate 3-nerved when dry, petals obovate and as well 
as the capsule somewhat longer than the lanceolate acuminate 
3-nerved sepals. E. B. t. 512. Alsine Wahl. 
Rocky and mountainous pastures, in the north of England, Wales, 
and Cornwall; abundant on Arthur’s Seat and in other places about 
Edinburgh ; Mael Duncroisg, Breadalbane : not found in the west 
of Scotland. 7£. 5 — 7. — Stems 3 — 4 inches high, slightly hairy, 
as are the calyces and peduncles. The leaves are usually acute or mu- 
cronate, but in the Cornish form, supposed to be the obscure A. 
Gerardi Willd., they are bluntish ; lower ones crowded, often curved. 
2. A. rubella Hook, (alpine S .) ; stems numerous, peduncles 
terminal downy mostly single-flowered, leaves linear-subulate

Near the summits of the Breadalbane mountains, among soil and 
broken rocks, rare. Ben Hope, Sutherland. If.. 7, 8 This is 
quite an alpine or arctic plant. It loves to grow with its root buried 
under a loose piece of rock, and late in the summer often acquires a 
reddish tinge. Stamens from a glandular disk. Styles usually 4, 
sometimes 3 or 5 ; the valves of the capsule are, consequently, equally 
variable. 
3. A. uligindsa Schl. (Bog S .) ; stems prostrate at the base, 
then erect with 1 — 3 flowers on long slender peduncles, leaves 
subulate semiterete bluntish nerveless, sepals ovate acute 3- 
nerved about as long as the oblong-obovate petals. E. B. S.
