Species

Angiosperms > Santalales > Santalaceae > Viscum

Characteristics

Leafy, dioecious shrubs, up to 1 m or higher, sometimes glaucous, mostly pale green; younger branches usually 6-ribbed; older branches rounded with often swollen nodes; basal internodes of younger branches (25-)35-40 x 1-2 mm, often dilated at nodes. Leaves oblanceolate-obovate, highly variable in size (15-)25-35(-50) x 8-15 mm, rounded apically, cuneate into base, 3-nerved basally (sometimes only faintly so), occasionally glaucous; petioles rather indistinct when merging into blade, c. 3-4 mm long. Staminate flowers in sessile axillary dichasia, 2-3 per axil (sometimes accessory flowers developing laterally and increasing the number to 5). Pistillate flowers solitary in bracteal cups, these born singly, or in fascicles of 2-3 per axil. Berries ellipsoid-globose, 6-7 mm long, developing a relatively long (4-5 mm) pedicel slightly widening towards the apex at maturity, smooth, whitish cream to light pink; style persistent.
