Visewm. } CXIX. LORANTHACEA (SPRAGUE). 405 
breticola by its shorter internodes and pedicelled berries, which are usually con- 
spicuously warted. It is a native of Transkei, Tembuland, Pondoland and Natal. 
Two other African species, V. ugandense, Sprague, and V. Engleri, Van Tiegh., 
have been confused with V. dichotomum, Don. The four African species which have 
been referred to V. dichotomum differ from it in the nature of their berries and in 
being dicecious, 
V., dichotomum, D. Don, which has been reduced to V. articulatum, Burm. f., by 
Hook. fil. Fl. Brit. Ind. v. 226, is a moneecious species, native of India, Malaya, 
Indo-China and China. Each bracteal cup bears either a solitary female flower or 
3-flowered cymule, of which the central flower is female and the two lateral male. 
The Australian and Polynesian material referred to V. articulatum by Seem. FI. 
Vitien. 120, Benth. Fl. Austr. iii. 396, and others, differs from that species in having 
persistent petals and belongs to several species of the genus Korthalsella. According 
to Engler in Engl. & Prantl, Pflanzenfam. Nachtr. i. 188, Korthalsella differs from 
Viscum in having 2-celled anthers, which dehisce by two longitudinal slits. 
15. V. ugandense, Sprague. A much-branched shrub. Branches 
and branchlets conspicuously flattened, ribbed in a dried state; inter- 
nodes varying from linear to oblanceolate, tape-like, broadest in their 
upper part, slightly contracted at the apex, slightly tapering into the 
base, 2—2 in. long, 14-34 lin. broad, those of the main branches much 
thickened along the middle. Flowers dicecious, tetramerous. Male 
inflorescences composed of 3 3-flowered (more rarely 2-flowered) cymules, 
each of which is borne bya bracteal cup. Bracteal cups sessile, broadly 
trough-shaped, 13 lin. long, { lin. broad; lobes patulous, rounded, 
% lin. long; solid base of flower } lin. long. Receptacular tube $ lin. 
tong. Petals deltoid-ovate, 3 lin. long, ;°,-1} lin. broad, slightly re- 
curved at the apex. Anthers elliptic-oblong in outline, 3-? lin. long, 
3-$ lin. broad. Female inflorescences composed of 1 or 3 flowers, each 
of which is borne by a bracteal cup. Bracteal cup conspicuously 2-lobed, 
$-I lin, high ; lobes ascending or suberect, } lin. long, exceeding or sub- 
equal to the receptacle at the time of expansion of the flower. Re- 
ceptacle obovoid-oblong, % lin. long. Petals % lin. long, deciduous, 
alternately narrowly triangular, acute, $ lin. broad, and deltoid-ovate, 
2 lin. broad. Stigma subsessile, projecting 4~} lin. above the insertion 
of the petals. Berry sessile, broadly ovoid, 3 lin. long, smooth.—

__, The type of V. ugandense is Dawe, 473, from which the description of the female 
inflorescence and fruit has been drawn up. The male inflorescence bas been described 
from Bagshawe, 1094, which comes from the same district and is apparently con- 
specific. In the diccious leafless species of Viscum, it is often very difficult to 
determine a male specimen, as the specific characters reside chiefly in the berry and 
female inflorescence,
