shortly exserted beyond the lobes of the involucre and curved to one 
side, 2 lin. in diam., rather acutely 3-angled, obscurely and minutely 
puberulous ; perianth rudimentary; styles about lin. long, united below, 
bifid at the apex.—Pax in Engl. Pfl. Ost-Afr. C. 242.

Var. puberulum, N. E. Br. Leaves 5-63 in. long, 2-23 in. broad, cuneate- 
oblanceolate. Umbels with the secondary rays forked and more pubescent than in 
the type. Involucre 3 lin. in diam., pubescent outside and the lobes pubescent on 
the back at the basal part.

The type of var. puberulum consists of 4 leaves and 2 umbels only ; when better 
known it may prove to be a distinct species. The umbels closely resemble those of 
8. compactum, N. E. Br., but the leaves are larger and quite destitute of the wing- 
like keel on the midrib beneath, characteristic of the latter species. 
4. S. compactum, JV. Z. Br. Branches as in S. Grantii, but perhaps 
rather stouter, glabrous. Leaves thinly fleshy, 3-43 in. long, 12-23 in. 
broad, cuneately obovate, broadly rounded into a very short recurved 
acute point at the apex, narrowing from a little above the middle to the 
subsessile base, rather finely and serrately crinkled at the subrevolute 
margins, with an acute wing-like keel along the midrib beneath, 3-1 lin. 
broad at the basal part, glabrous on both sides. Peduncle ?~-1 in. long, 
moderately stout, glabrous, bearing a compact corymb-like umbel 13- 
2} in. in diam. of 4 puberulous rays, which are twice forked, with a 
Sessile involucre in each fork and 1-3 at the end of each branchlet ; 
bracts 51. in. long, 4 in. broad, transversely rectangular, minutely 
toothed along the truncate top, with here and there a gland, very finely 
ciliate down the sides, puberulous on the back and part of the inner 
surface. Involucre about 1 in. in diam. and scarcely ;); in. deep, 
Saucer-like, open or notched on one side to half-way down (always ?) 
with a very spreading entire margin (gland), apparently bright red ; 
lobes erect, much overtopping the gland, slightly puberulous at the base 
on the back, otherwise glabrous on both sides. Ovary and capsule 
erect, minutely puberulous; perianth-lobes very minute, rounded ; styles 
connate at the base, shortly bifid at the apex, with roundish stigmas, 
thinly puberulous, at least on the lower part.

5. S. carinatum, Boiss. in DC. Prodr. xv. ii. 187, 1269. A 
shrub or small tree 6 ft. or more high. Branches terete, fleshy, green, 
With age becoming grey, marked with leaf-scars. Leaves alternate, 
33-5 in, long, 13-2} in. broad, obovate or oblong-obovate, acute or 
abruptly and obtusely acuminate or subacuminate, tapering to a sub- 
Sessile base, entire or crisped-crenulate on the margins, acutely keeled 
on the midrib beneath, glabrous on both sides. Cymes axillary and ter- 
minal, somewhat lax, 2-21 in, in diam.; peduncles 1-1} in. long, sub- 
umbellately branching into 3-5 closely-placed rays, but not all arising at 
the same point; rays 2-3 times forked; bracts transverse, truncate,
