The Santalales is a largely parasitic order of plants. The only one of its families that is known to have native or naturalized members in New York is the Santalaceae.

Family Santalaceae

Comandra clade

Also treated as the Comandraceae[1] (bastard-toadflax family), this group contains only the two species bastard toadflax (Comandra umbellata) and false toadflax (Geocaulon lividum), both of which are native to New York. ↑ D.L. Nickrent et al. (2010) "A revised classification of Sanalales." Taxon 59(2):538-558, 4 Apr 2010.

Cervantesia clade

Also treated as the family Cervantesiaceae,[1] this is a group of parasitic flowering plants. Its only native or naturalized New York genus is Pyrularia. ↑ D.L.Nickrent et al. (2010) "A revised classification of Sanalales." Taxon 59(2):538-558, 4 Apr 2010.

Pyrularia

Pyrularia pubera buffalo-nut Pyrularia contains two species native to the Himalayas of China and one native to the southeastern United States. Buffalonut (Pyrularia pubera) is a root-parasitic shrub, Native to the Appalachians and foothills from Southern Pennsylvania to Alabama and Georgia.[1] It appears to have naturalized on Long Island. ↑ Kim D.

Viscum clade

Also treated as the family Viscaceae or tribe Visceae,[1] this group contains seven genera worldwide, two of which have single New York native species. These are branch parasites ↑ Angiosperm Phylogeny Website for the order Santalales, 25 June 2015

Arceuthobium

Arceuthobium pusillum dwarf mistletoe Arceuthobium pusillum or dwarf mistletoe parasitizes the branches of spruce, pine, and tamarack trees and is one of many causes for the deformations known as "witches brooms" seen on those trees.

Phoradendron

Phoradendron leucarpum American mistletoe American mistletoe (Phoradendron leucarpum) is believed to be native to Staten Island where it was reported growing on blackgum (Nyssa sylvatica) trees until sometime prior to 1879. It is now considered to be extirpated from New York State.

↑ A pending conservation proposal would change the basionym of Phoradendron leucarpum from Viscum leucarpum to Viscum serotinum, avoiding the P. leucocarpum homonym and making the accepted name Phoradendron serotinum.
