INFLORESCENCE: staminate spikes with 2-3 fertile segments, ca. 6 flowers per fertile segment; pistillate spikes with ca. 3 fertile segments, 2-3 flowers per segment
Flowers: sunken along the axis; perianth segments usually 3, persistent in fruit; staminate flower with a sessile minute (less than 2 mm), 2-chambered anther; pistillate flower with a single style and rounded stigma
Fruit: white-reddish, glabrous, ca. 3 mm in diameter
Misc: 50-1400 m (50-4600 ft); Jan-Mar

Duration: Perennial
Nativity: Native
Lifeform: Subshrub
General: Branches arching to drooping, often forming much branched masses in desert trees, especially legumes. Stems terete, at first silvery-green pubescent with minute, appressed scalelike hairs, soon glabrous and green to reddish green.
Leaves: Closely appressed to stem, 1-2.5 mm, at first green or yellow-green and quickly drying as persistent scales or remaining green only at base.
Flowers: Dioecious or occasionally monoecious; fragrant, calyx thick, fleshy, and yellow-green; anthers short and yellow; perianth segments usually three, persistent in fruit; pistillate flower with a single style and rounded stigma.
Fruits: Globose, 4.5-5.5 mm when fresh, the fresh pulp viscid and translucent white, salmon colored on exposed surfaces and whitish to yellow-white when not exposed to sunlight. Explosive dehiscence.
Ecology: Found on host plants through southwest; flowers December-February.
Distribution: c and s CA, c and s NV, AZ, s UT, s NM; south to n MEX.
Notes: Phoradendron can be distinguished partially by their host plant. P californicum distinguished by growing on Legumes (Prosopis, Olneya, Acacia etc..) and also the leaves which are reduced to scales. Flowering and fruiting non-seasonally, birds love this species and help to spread.
Ethnobotany: Decoction of the berries was taken as purge by the Pima. It was used for washing sores, for stomachaches, boiled, dried and stored for food.
Etymology: Phoradendron is from Greek phor, a thief and dendron, tree-hence tree thief because of its parasitism, while californicum refers to California.
Synonyms: Phoradendron californicum var. distans, P. californicum var. leucocarpum
