1. V. Holstii, Lngl. in Engl. Jahrb. xx. 132. Stem terete, about 
3 lin. in diam. 10 in. below the apex of the branchlets, very finely ribbed 
in a dried state, greyish-brown, glabrous, internodes up to 1} in. long; 
younger branches and branchlets distinctly ribbed ; internodes of the 
branchlets 5-10 lin. long, the uppermost one or two distinctly compressed, 
Strongly 6—-8-ribbed, with 1 rib on each edge and 2-3 on each face. 
Leaves broadly obovate or suborbicular, rounded at the apex, rather 
abruptly contracted into a cuneate base, 7-12 lin. long, 4-9 lin. broad, 
minutely crenulate, coriaceous, glabrous, inconspicuously 3-nerved from 
the base (sometimes with 2 additional less distinct lateral nerves) ; 
petiole $-1lin.long. Inflorescences axillary, sessile, fascicled or solitary. 
Flowers monccious, tetramerous, the female solitary, the male 2-3 
together in each bracteal cup. Male inflorescence: Bracteal cup boat- 
shaped, 1 lin. long, { lin. high including the lobes, $ lin. high in the

Viscum Holstii seems to differ from V. tuberculatum in little but the shape of 
the bracteal cup. In the somewhat scanty material of V. Holstii available for 
examination I have found that the number of bracteal cups in each axil varies from 
one to five, and that each cup bears either a solitary female flower or 2-3 male 
flowers. If this arrangement of the male and female flowers in separate bracteal
