Forest Plants of Eastern India By Amal Bhusan Chaudhuri (1993)- Brief details with keys– . BSI Mahar. flora mentions only two species of Leafless parasites from Genus Viscum. . Here are the differentiating features:
Viscum album V. articulatum (inc. var. dichotomum)
Plants dioicious, branching apical Plants monecious, becoming pendulous
Stems terete stems flattened, 3-ridged
Internodes 3-7 cm long internodes 1.5-2.5 cm long
Leaves usually obovate, 3-5 cm long leaves reduced yo scarious scales
Inflorescence terminal, 3-5 flowered spikes, inflorescence axillary, 1-3 together, 3-flowered
Male 3-fld, female 3-5-fld central flower female, lateral male
Berry greenish-white, globose, ca 6 mm Berry greenish-white, globose 3-4 mm
In Viscum ramosissimum, the internodes are cylindric (terete), i hope. . In Viscum album the leaf is strap-shaped where as in this species (V.monoicum) of Viscum the leaf is some what falcate, coriaceous, attenuated at the base to a short petiole (these characters are found in V.monoicum). According to this two flora only two species of Viscum are found in Assam i.e V. articulatum and V. monoicum. The first (V. articulatum) is leafless. . Viscum : 1 post by 1 author.
I have updated eFI (efloraofindia) page on Viscum Attempts have been made to incorporate most of the species available in India & nearby areas with details & keys directly or through links as far as possible. It’s quite possible that there may be some discrepancy in the accepted names & synonyms taken from other links. Species discussed so far in efloraofindia are given at the bottom of the page in the form of links against Subpages. On clicking them one can see all the details. If someone can provide complete list of Indian species with source references it will be wonderful. Any comments/ corrections are welcome.

POWO treated Viscum nepalense Spreng and Viscum articulatum Burm.f. are two different species. I have seen these in some articles, they are treated as one species. V. nepalense is synonymous to latter. Are there any taxonomic revision of the genus Viscum from the Himalayan or Asian regions. Thank you.
