536 CXXII, EUPHORBIACEZ (BROWN). | Luphorbia. 
broken up into a corymbose cyme of forked branches, glabrous. Bracts 
3-5 lin. long and broad, orbicular-ovate, obtuse or rounded, apiculate, 
broadly rounded at the sessile base, entire or subdenticulate, with very 
narrow cartilaginous margins, those at the base of the umbel 6-8 lin. 
long, 2-3 lin. broad, oblong, oblong-lanceolate or ovate-lanceolate, 
minutely denticulate, deflexed, all glabrous on both sides. Involucre 
sessile, when mature 14-12 lin. in diam., cup-shaped, glabrous, with 
4 glands and 5 subquadrate toothed or subentire more or less ciliate 
lobes; glands }-1 lin. in their greater diam., transversely oblong, with 
a straight dorsal margin and a minute tooth (scarcely a horn) at each 
end of it. Capsule about 14 lin. long, somewhat ovoid, obtusely 3-angled, 
glabrous, exserted on a recurved pedicel ; styles 3—? lin. long, nearly free 
or shortly united at the base, bifid at theapex. Seeds about 1 lin. long, 
oblong, 4-angled, subtruncate at each end, obscurely rugulose, caruncu- 
late.—L.. cebrina, Hochst. ex Klotzsch & Garcke in Abh. Akad. Berlin,

This is closely allied to Z. schimperiana, Scheele, but is possibly perennial, with 
several stems to a root and more densely leafy; the minutely toothed and smaller 
leaves and larger involucres also sufficiently distinguish it. The ovary does not 
appear to become exserted from the involucre at so early a stage as it does in 
E. schimperiana. The description is made from the type kindly lent by Prof. 
Lecomte.

Annual? Stem 2-4 ft. high, hollow, glabrous, divided at the apex into 
a 5-rayed umbel of repeatedly forked lax cymes, with few or several 
similar cyme-branches arising from the axils of the leaves below the 
umbel. Leaves alternate, with a whorl of 5 at the base of the umbel, 
14-3} in. long, 2-4 lin. broad, lanceolate-linear, subacute, narrowed ab 
the base into a short petiole, glabrous on both sides. Rays of the 
umbel and cyme-branches 4-10 in. long. Bracts subsessile, very 
spreading, }-1 in. long, 14-34 lin. broad, ovate or lanceolate, acute @ 
obtuse, rounded at the base, glabrous on both sides. Involucre solitary 
at the forks or nodes of the cymes, shortly pedunculate, 1 lin. in diam., 
campanulate, with 4 glands and 5 subquadrate lobes, bifid or subtruncate 
at the apex, ciliate; glands about 4 lin. in their greater diam., transverse, 
crescent-shaped, with the 2 short horns usually much incurved, some- 
times nearly or quite meeting, ‘occasionally they are nearly or quite 
. absent and the gland is merely notched or almost entire on the outer 
margin, all forms are found on the same plant. Capsule about 1} lin. 
in diam., smooth, glabrous ; styles 4-4 lin. long, free, shortly bifid at the 
apex. Seeds not seen.—Boiss. in DC. Prodr. xv. ii. 156; Engl. Hi rik
