Euphorbia. CXXII, EUPHORBIACEE (BROWN). 595 
ip | 
with a small solid central part, glabrous; angles wing-like, scarcely 
toothed, Spines 4 in. long, in pairs about ? in. apart, diverging, dark 
brown. Flowering-eyes about } in. above the spine-pairs. Cymes 3-6 
from each flowering-eye, with peduncles 3-5 lin. long, each with 1 sessile 
involucre or | sessile and 1 or 2 shortly pedunculate involucres, glabrous. 
Bracts thin, submembranous, adpressed to the involucres, } in. long, 
$ in. broad, broadly rounded. Involucres about 4 lin. in diam. and 
2-2} lin. deep, cup-shaped, glabrous, with 5 glands and 5 transversely 
oblong fringed lobes; glands not contiguous, 14—2 lin. in their greater 
diam., transverse, reniform or somewhat half-circular, slightly 2-lipped, 
entire, more or less undulate when dried. Ovary sessile, included in 
the involucve, compressed, 2-celled, fleshy, glabrous, with a calyx divided 
into several linear or linear-filiform segments as long as the ovary; 
styles 2, about 1? lin. long, moderately stout, shortly united at the base, 
then recurved-spreading, entire at the apex. 
Nile Land. British East Africa: Kibwezi, Scheffler, 335 ! 
Closely related to Z. calycina, N. E. Br., and having the same kind of conspicuous 
calyx, but the involucre is larger, the ovary is sessile, included in the involucre, 
and appears to be constantly 2-celled, and the 2 styles are longer and stouter than in 
- calycina, 
151. E. acrurensis, V. #. Br. Arborescent, succulent, spiny. 
Branches of the dried specimens seen 7-angled and about 44 in.in diam., 
with the solid central part about 1-1} in. thick and much less in diam. 
than the angles are broad (seedling plant 3-angled and 1-1} in. in 
diam.) ; angles wing-like, 2 in. broad and 2 lin. thick at the edge in the 
dried specimen, with triangular channels 1? in. deep between them. 
Leaves not seen. Spines 14-5 lin. long, in pairs, diverging, stout at 
the base, blackish-grey on the seedling, becoming grey with darker tips 
With age, on suborbicular horny shields 3-4 lin. in diam. on the mature 
branch, much smaller on the seedling, not connected by a horny border 
along the angles, becoming grey with age, with the flowering-eye touching 
or subincluded in their apical part. Cymes (detached, but distributed 
with the stem-sections) on peduncles }-4 in. long, bearing 3 involucres, 
the middle one sessile and the two lateral on cyme-branches 1 lin. long, 
glabrous. Bracts thin, adpressed, broken, but apparently suborbicular 
and about 3 lin. long and 24-34 lin. broad, very concave. Involucres 
$ in. in diam., cup-shaped, golden-yellow (Schweinfurth), with 5-8 
glands and 5-8 transver-ely rectangular fringed lobes, glabrous ; glands 
13-2 lin. in their greater diam., erect in dried flowers, transverse, reni- 
form, with the middle of the inner margin turned in and forming a 
small lip, or crescent-shaped, with the inner margin concave, in dried 
‘Pecimens with the outer margin more or less incurved. Ovary sub- 
‘essile and included when young, in fruit exserted and curved to one 
“ on a short stout pedicel, glabrous; perianth fleshy, with 3 lobes 
<~23 lin. long, deeply cut into 2 or more filiform segments or entire 
and subulate-acuminate, in fruit reflexed and the segments often broken 
off; styles 1?-2 lin. long, shortly united at the base, rather stout, 
slightly thickened and minutely 2-lobed at the apex. Capsule 5-6 lin.
