Description

Plants often rather small, glabrous, erect; internodes sharply quadrangular at least when young; basal cataphylls 1, nearly axillary, inconspicuous. Petiole indistinct; blade obovate to lanceolate-spatulate, 2-5 cm, apex rounded, base cuneate. Monoecious. Inflorescence to 2.5 cm or more, 1-3 in leaf axils, mostly lacking sterile bracts; fertile internodes 3-6; flowers mostly to 9 per fertile bract, 2-seriate. Fruit yellow or slightly orange (not red), spherical, 0.2-0.3 cm in diam., perianth segments closed.

Distribution

Argentina present, C America present, French Guiana present, Greater Antilles present, Northern America, Southern America: Bolivia (Bolivia present), Suriname present, northern Paraguay present, south to amazonian Peru present
Probably the most widespread of all American mistletoes, ranging from Mexico, C America, the Greater Antilles, south to amazonian Peru and Bolivia and northern Paraguay and Argentina, surprisingly not yet recorded from Suriname or French Guiana; 1000+ collections studied (GU: 2).

Notes

With respect to Rizzini's decision (1978: 82-84) to place P. quadrangulare in synonymy to P. rubrum (L.) Griseb., see the discussions in Kellogg & Howard (1986: 86-88) and Kuijt (2003: 369-376).
