_ 464 CXXH. EUPHORBIACEX (BROWN). [ Synadeniums 
acute, minutely and indistinctly crinkled at the edges, with an acute 
wing-like keel along the midrib beneath, glabrous on both sides, 
deciduous. Umbels axillary, pedunculate, simple, 4—5-rayed ; peduncles 
1-3 in. long, fleshy, slightly puberulous down one side; rays 4-} in. 
long, each bearing 1 involucre, subclavate, fleshy, pubescent with 
spreading hairs ; bracts 1-14 lin. long and broad, subquadrate or broadly 
ovate, pubescent, very minutely gland-toothed. Involucre 24-23 lin. 
in diam. and about 14 lin. deep, cup- or shallowly basin-shaped, 
pubescent on the basal part, with an entire spreading rim-like gland ; 
lobes overtopping the gland, thinly pubescent on both sides. Ovary 
adpressed-puberulous; perianth reduced to a mere rim; styles shortly 
united at the base, divided to nearly half-way .down into 2 filiform 
stigmas, pubescent.

Described from a very short branch preserved in fluid. According to the 
collector “ the Jeaves fall off in the dry season, and it then looks like a Cactus.” 
2. S. Volkensii, Pax in Engl. Pf. Ost-Afr. C, 245. Branches 
as in S. Grantii, Hook. f., glabrous. Leaves 4-5 in. long, 2-24 in. 
broad, rather thickly coriaceous, probably fleshy when alive, elliptic, 
elliptic-obovate or obovate-oblong, rounded into a short deltoid point at 
the apex, cuneately narrowed from the middle or below into a very 
short stout petiole, minutely serrate, glabrous on both sides ; midrib 
apparently neither acute nor keeled beneath, unless perhaps slightly 
towards the apex. Peduncles about 1 in. long, branching at the apex 
into a simple umbel of 3-4 rays 1—-} in. long surrounding @ sessile 
involucre, shortly pubescent. Bracts } in. long and nearly as broad, 
cuneately subquadrate, often slightly hooded at the truncately-rounded 
apex, pubescent on both sides. Involucres solitary at the apex of each 
ray and one sessile between the bases of the rays, 33 lin. in diam, 
shallowly cup-like, with a very spreading rim-like entire gland ; lobes 
wholly overtopping the gland. Ovary, styles and pedicel pubescent ; 
perianth with very rudimentary rounded lobules; styles connate at the 
base, deeply divided into 6 rather slenderly pointed subulate arms~

S. Grantii, Hook. f., glabrous. Leaves alternate, 3-44 in. long, 1}-13 = 
broad, cuneately oblanceolate or obovate, abruptly acute or with a short 
deltoid point, tapering to the subsessile or very shortly petiolate base, 
with the midrib prominent and rounded (not wing-keeled) beneath. 
Umbels axillary, compound ; peduncles 3-1 in. long, glabrous, with 3-9 
primary glabrous rays 4-3} in. long and 3-4 secondary thinly enone : 
rays 3-5 lin. long; bracts rectangular or quadrate, truncate, i 
pubescent. Involucre 2} lin. in diam., shortly and broadly fuppel- 
shaped, with an entire spreading margin, glabrous outside, red ; lobes 
erect, transversely rectangular, ciliate, glabrous on the back, red. Capsule
