Viscum stenocarpum

Primary tabs

Viscum stenocarpum


Plant slender to moderately robust, erect or pendulous, to 1 m long. Leaves rudimentary, spreading, 0.2-0.5 mm long. Inflorescences 1 or sometimes 2 in the axils, rarely with subsidiary cymules developing lateral to the first one, a sessile cymule of 3 flowers, subtended by a cupule 0.5-1 mm long, with the middle flower female and the lateral flowers male. Fruit ellipsoid to almost globose, sessile, smooth, yellow to red, often striate.


Asia-Tropical: Borneo present; Jawa (Jawa present); Sulawesi (Sulawesi present); Sumatera (Sumatera present)
Malesia: Sumatra, Java, Celebes; possibly Borneo.


Danser in and reduced V. stenocarpum to synonymy with V. liquidambaricolum Hayata of mainland Southeast Asia, primarily on the similar fruit characters. The latter species has flattened internodes and in vegetative characters differs sharply from V. stenocarpum in the same way as V. nepalense differs from V. articulatum (see notes there). Viscum stenocarpum is accordingly treated as distinct from, although closely related to V. liquidambaricolum. Two specimens seen from northern Borneo show a combination of characters of V. articulatum and V. stenocarpum, suggesting local introgression between these two species. Similar to V. articulatum, differing in the often more nearly terete stems more prominently ribbed, the usual absence of subsidiary cymules, the shape and colour of the fruits, and probably in host preference.
