PLANTS: Aerial shrubs parasitic on dicot or coniferous shrubs and trees, 2-15 dm high, woody, glabrous or hairy, dioecious in AZ (some tropical species monoecious). SHOOTS: usually some shade of green, but sometimes reddish. LEAVES: simple, entire, decussate, but reduced to minute scales in 2 species. INFLORESCENCE: axillary spikes with 1-7 fertile segments. 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: 3-6 mm in diameter, sessile, white, pink, or reddish; eaten and dispersed by birds. (Greek: phor = thief + dendron = tree).
