pubescent, exserted on a pubescent pedicel about 4 lin. long; styles 1 lin. 
long, united to the middle or slightly beyond, puberulous, with spread- 
ing arms, channelled above and 2-lobed at thea pex. Capsule 5 lin. in 
diam., subglobose, obscurely trigonous, pubescent, with woody cell-walls

This may be the plant quoted by Pax as Z. Tirucalli, Linn., in Bull. Soc. Bot. 
Belg. xxxvii. 108; in De Wild. & Durand, Contrib. Fl. Congo, i. 52, and Reliq. 
Dewevr. 203, and in De Wild. Miss. &. Laurent, i. 143. But it is quite distinct 
from the true Z. Tirucalli, Linn., which is an Indian plant. 
105. E. scoparia, V. #. Br. A tree 15-25 ft. high. Branchlets 
alternate and usually clustered at the ends of larger branches, terete, 
succulent, spineless, leafless except when very;young, 3-3 lin. thick, 
marked with small leaf-scars, glabrous. Leaves soon deciduous, alternate, 
distant below, clustered at the ends of the branchlets, 4-3 in. long, 
$-} lin, broad, linear or cuneately linear, subacute, sessile, somewhat 
fleshy, glabrous. Inflorescence a small dense sessile cluster of involucres 
at the tips of the branchlets, about }-} in. in diam. Bracts minute, 
scale-like, suborbicular. Involucres subsessile or very shortly peduncu- 
late, scarcely 1 lin. in diam., cup-shaped, glabrous, with 5 glands and 5 
or fewer oblong or ovate subciliate lobes ; glands }-} lin. in their greater 
diam., transversely elliptic, entire. Ovary erect, on a stout pedicel about 
as long as the involucre, glabrous ; styles 4+ lin. long, free, very deeply 
bifid, — Z. Tirucalli, Schweinf. in Bull. Herb. Boiss. vii. App. ii. 316,

The name Z. Tirucallihas been applied to several African species of Euphorbia, 
bat all of them are very distinct from the true ZH, Tirucalli, Linn., which is a native 
of India, although in the Flora of British India it is stated to have been probably 
Introduced there from Africa. There is, however, no evidence of this and the Indian 
Plant is certainly perfectly distinct from all the African specimens I have seen. 
106. E. negromontana, V. £. Br. A succulent shrub 3-4 ft. high, 
leafless and spineless, dichotomously or trichotomously much-branched 
rom the base, fleshy, glaucous, probably dicecious ; stems or branches 
in. thick in the specimens seen, terete, glabrous; branchlets 
®pposite, articulated to the branches, 1-1} lin. thick (dried), probably 
5. Hn. or more thick when alive, with the barren ones 4—6 in. long, 
verging, straight, and the flowering abbreviated into joints 4-4 in. long 
‘nd more or less congested or clustered. Leaves opposite, rudimen- 
tary, reduced to very minute scales. Involucres solitary or 3 together,
