Duration: Perennial Nativity: Native Lifeform: Subshrub General: Perennial, aerial parasitic subshrub, much-branched, herbage greenish-yellow to brown. Leaves: Mostly less than 10 mm wide, linear-spatulate to oblong, not more than 10 mm wide, sessile or subsessile. Flowers: Two per node, borne on pistillate spikes not more than 5 mm long, spikes 1-2 jointed, calyx of both male and females flowers 3-lobed, staminate ones 6-12 flowered, pistillate ones with 2 flowers at each node, anthers 2-celled. Fruits: White or straw-colored globose berries. Ecology: Found on Abies concolor, Juniperus, and Cupressus from 3,500-7,000 ft (1067-2134 m). Notes: The keys to this species are the pistillate flowers 2 per node, the leaves linear-spatulate to oblong, less than 10 mm wide, sessile or subsessile, and the spikes of the flower not more than 5 mm long. Ethnobotany: Uncertain, but other species in the genera have uses. Etymology: Phoradendron is from Greek phor, a thief and dendron, tree-hence tree thief because of its parasitism, while bolleanum is of uncertain origin. Synonyms: None Editor: SBuckley, 2010, LCrumbacher 2011

Duration: Perennial Nativity: Native Lifeform: Shrub General: Aerial parasitic shrub with shoots 30-60 cm long, glabrous, green with internodes 1-2 cm long. Leaves: Oblanceolate, 1.5-3 cm long, 5-10 mm wide, glabrous. Flowers: Inflorescence with staminate spikes bearing 1-2 fertile segments with 8-12 flowers; pistillate spikes with 1 fertile segment and 2 flowers; flowers usually glabrous. Fruits: Berrylike, white-pinkish, glabrous and about 4 mm in diameter. Ecology: Found on Abies concolor in mixed conifer forests from 7,000-8,500 ft (2134-2591 m); flowers July-August. Notes: Note the inclusion of the former P. bolleanum into this species name, this expanded circumscription has expanded its range. Ethnobotany: Unknown, but other species in the genera have uses. Etymology: Phoradendron is from Greek phor, a thief and dendron, tree-hence tree thief because of its parasitism, while pauciflorum means few flowered.

Duration: Perennial Nativity: Native Lifeform: Shrub General: Perennial, aerial parasitic subshrub with shoots 30-50 cm long, green, glabrous, with internodes 8-15 mm long. Leaves: Oblanceolate to oblong, sessile, 1.5-2.5 cm long, 2-3 mm wide, glabrous. Flowers: Staminate spikes with usually 1 fertile segment; usually with 6-10 flowers per segment; pistillate spikes with usually 1 fertile segment and 2 flowers per segment; flowers are glabrous, white-pinkish, sunken along axis and 4 mm in diameter; perianth segments usually three, persistent in fruit; pistillate flower with a single style and rounded stigma. Fruits: Mucilaginous berry, 3-6 mm in diameter, sessile, explosively dehiscent. Ecology: Found on Cupressus arizonicus from 3,500-5,500 ft (1067-1676 m); flowers June-August. Notes: Distinguished by its glabrous leaves and being found on Cupressus arizonicus. Ethnobotany: Unknown, but other species in the genera have a variety of uses. Etymology: Phoradendron is from Greek phor, a thief and dendron, tree-hence tree thief because of its parasitism, while densum means dense, referring to its dense habit.
