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., 

 Imve been confused with V. dichotomum, Don. The four Af ricnn species which liave 

 been referred to V. dichotomum differ from it in the nature of their berries and in 

 being dioecious. 



V. dichotomum, D. Don, which has been reduced to V. articulatutn, Burin, f ,, by 

 Hook. fil. Fl. Brit. Ind. v. 226, is a monoecious species, native of India, Malaya, 

 Tndo-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, Beuth. 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. 138, Korthalsella differs from 

 Viscum, in having 2-celled anthers, which dehisce by two longitudinal slits. 



15. V, ugandense, AS'/jrrtf/ite. 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 th«ir 

 upper part, slightly contracted at the apex, slightly tapering into the 

 base, f-2 in. long, 1|— -^^ lin. broad, those of the main branches much 

 thickened along the middle. Flowers dioecious, tetramerous. Male 

 inflorescences composed of 8 8-floweied (more rarely 2-flowered) cymules, 

 each of which is borne by a bracteal cup. Bracteal cups sessile, broadly 

 trough-shaped, If lin. long, ^ lin. broad; lobes patulous, rounded, 

 |- lin. long ; solid base of flower J lin. long. Receptacular tube f lin. 

 long. Petals deltoid-ovate, f lin. long, yV-yJ ^i^* broad, slightly le- 

 curved at the apex. Anthers elliptic-oblong in outline, |-| lin. long, 

 J-| lin. broad. Female inflorescences composed of 1 or 3 flowers, each 

 of which is borne by a bracteal cup. Bracteal cup conspicuously 2-lobed, 

 ^1 lin. high ; lobes ascending or suberect, J lin. long, exceeding or sub- 

 equal to the receptacle at the time of expansion of the flower. Re- 

 ceptacle obovoid-oblong, f lin. long. Petals | lin. long, deciduous, 

 alternately narrowly triangular, acute, f lin. broad, and deltoid-ovate, 

 J lin. broad. Stigma subsessile, projecting J- J lin. above the insertion 

 of the petals. Berry sessile, broadly ovoid, 8 lin. long, smooth. —

The type of V. ugandense is Bawe, 473, from which the description of the female 

 inflorescence and fruit has been drawn up. The male inflorescence has been described 

 from Bagshaive, 1094, which comes from the same district and is apparently con- 

 specific. In the dioecious 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.
