Perennial, shrub, generally ± green, parasitic on aboveground parts of woody plants; dioecious [ monoecious].
Stem: brittle; 2° branches generally many.
Leaf: simple, entire, opposite, 4-ranked, with blade or scale-like (then each pair generally fused).
Inflorescence: spikes or cymes, axillary or terminal; bracts opposite, 4-ranked, scale-like, each pair fused.
Flower: unisexual, radial, 2–4 mm; perianth parts in 1 series.
Staminate flower: perianth parts 3–4(7); anthers generally sessile, opposite and generally on perianth parts.
Pistillate flower: perianth parts generally 2–4; ovary inferior, 1-chambered, style unbranched, stigma ± obscure.
Fruit: berry, shiny.
Seed: 1(2), without thickened coat, gelatinous.
7 genera, ± 450 species: tropics, generally n temperate. All parts of most members may be TOXIC. [Kuijt 2003 Syst Bot Monogr 66:1–643] Sometimes included in Loranthaceae; parasitic on plants in many other families. —Scientific Editor: Thomas J. Rosatti.

Perennial, shrub, woody at least at base, glabrous or short-hairy.Key to Phoradendron
Stem: generally > 20 cm, not angled, green, less often ± red.
Leaf: with blade or < 1 mm, scale-like.
Inflorescence: spikes, few- to many-flowered, peduncled; flowers ± sunken into axis.
Flower: perianth parts generally 3.
Staminate flower: anthers 2-chambered.
Pistillate flower: perianth parts persistent.
Fruit: ± 3–6 mm, ± spheric, 1-colored, white, pink, or ± red, bird-dispersed; pedicel 0.
n=14.
± 240 species: temperate, tropical America. (Greek: tree thief) [Kuijt 2003 Syst Bot Monogr 66:1–643]
Unabridged note: Phoradendron serotinum (DC.) A. Gray collected in TX for sale nationally in Christmas trade; other species similarly important locally. Plants at some sites (e.g., Pinnacles National Monument) don't conform to key(s) and/or descriptions, as to hosts and/or morphology (see Kuijt, 2003); such problems thus far unsolved, though minimized here.

| Bioregions in which taxon occurs | Red area (if present) is the part of the bioregion lying between the upper and lower elevation limits of the taxon; markers link to CCH specimen records. If the markers are obscured, reload the page [or change window size and reload]. Yellow markers indicate records that may provide evidence for eFlora range revision or may have georeferencing or identification issues. |
