CLASS XXI, ORDER I. | EUPHORBIA. 1141 
sub-globose, with three obtuse lobes, each lobe with a smooth de- 
pressed line down the back, and on each side more or less waved 
with rough elevated dots, each cell containing an ovate seed, of a 
brownish colour, with a central line, and netted, and more or less 
pitted all over. 
Habitat.—Sandy sea coasts in the South and West of England, 
Wales, Isle of Man, South of Scotland, and about Dublin, Iveland ; 
but not common. 
Perennial ; flowering in August. 
This is a variable plant in size; specimens which we have from 
Portland Isle are above a foot high, scarcely branched, and of a 
somewhat leathery texture. Those which we have from near the 
Mull of Galloway, Scotland, are scarcely half the size, more branched 
and bent at the base, and the leaves of a more membranous texture. 
12. H. exig'ua, Linn. (Fig. 1271.) Dwarf Spurge. Leaves mem- 
branous linear, or linear, wedge-shaped, acute, or obtusely pointed, 
with a mucro, smooth, entire, sessile; umbel mostly of three prin- 
cipal branches, bifid; glands lunate, with long horns; bracteas ovate 
lanceolate, or wedge-shaped; capsules smooth, or nearly so ; seeds 
obovate, netted, brownish.

British Flora, ed. 4. vol. i. p. 328.—Lindley, Synopsis, p. 222. 
Root long, slender, the whole plant smooth, of a pale somewhat 
glaucous green. Stem erect, simple or branched from the base, 
slender, leafy. Zeaves sessile, narrow, linear, or tapering towards the 
point in a wedge-shaped manner, or linear and dilated at the point, 
and truncated with a mucro, forming a somewhat three lobed apex. 
Umbel mostly of three principal branches, sometimes five, bifid. 
Bractea ovate lanceolate, or wedge-shaped, and often somewhat 
heart-shaped at the base. Jnvolucre bell-shaped, smooth, its glands 
four, lunate, with two long slender horns. Capsule sub-globose, three 
lobed, each lobe keeled at the back, and more or less rough, with 
somewhat elevated points, or quite smooth. Seed ovate, somewhat 
four angled, a whiteish or ash colour, covered over with a net work 
of elevated warts. 
Habitat. Corn fields, especially in a sandy soil; frequent. 
Annual; flowering in July. 
This is the smallest of our Euphorbias, and one of the most 
variable. Sometimes it is erect, and scarcely branched, about a foot 
high; at others not more than three or four inches high, much 
branched and spreading, forming a very bushy little plant. When 
the ends of the leaves are dilated and lobed, it is the H#. rubra, De
