Viscum hoolei (Wiens) Polhill & Wiens

Species

Angiosperms > Santalales > Santalaceae > Viscum

Characteristics

Although this subspecies is monoecious, the distribution of pistillate and staminate flowers is not generally equal, and there is usually a predominance of one sex on flowering shoots, making the monoecious condition sometimes difficult to detect. Whereas the internodes of typical V. capense are usually shorter than 10 mm, stout, and of rather uniform dimensions (especially the population from the south-western Cape), those of subsp. hoolei are often longer than 10 mm, and the terminal and lateral shoots tend to be thinner than the primary shoots.
More
Leafless, monoecious, aerial, hemiparasitic subshrub, 0.3-0.5 m high, occasionally somewhat glaucous; internodes of stems rounded. Leaf scales acute, mostly on younger shoots. Staminate and pistillate flowers borne singly and sessile in bracteal cups, mostly 2 per node; staminate flowers with stamens united in a central synandrium. Flowering time July, Aug. Fruit a sessile, rotund berry, white, smooth; style persistent.
Leafless, except for scales on younger shoots, monoecious subshrub, up to 0.5 m high; commonly parasitic on species of Searsia (Rhus). Stems rounded; internodes 10-15 x 1-2 mm. Flowers: staminate and pistillate flowers borne singly and sessile in a bracteal cup; Aug.-May. Fruit sessile, rotund, smooth, white.
Like V. capense but monoecious, distal internodes 10-15 mm long and tapering apically to 1 mm wide, male flowers with united anthers.
Monoecious stem parasite to 50 cm. Leaves scale-like or lacking. Inflorescences bisexual. Berries sessile, smooth, white.
