Arceuthobium Sp. - Dwarf Mistletoe

Family: Santalaceae - Christmas Mistletoe (Previously in Viscaceae)^[E-flora]

Arceuthobium abietinum

Arceuthobium divaricatum

Arceuthobium cyanocarpum

"Perennial herb, shrub, glabrous. Stem: generally < 20 cm, ± angled at least when young, ± yellow, ± green, brown, purple; branches whorled or in 1 plane. Leaf: < 1 mm, scale-like. Inflorescence: generally spikes, peduncle short; flowers generally opposite, 4-ranked, less often whorled or 1, terminal. Staminate flower: perianth parts generally 3–4; anthers ± 1-chambered. Pistillate flower: perianth parts 2, persistent, minute. Fruit: generally 2–5 mm, broadly fusiform-spheric, 2-colored (1 color below, 1 above); pedicel short, recurved; seeds projected to 15 m by fruit explosion.
26 species: temperate, tropics northern hemisphere. (Greek: juniper, life) [Nickrent et al. 2004 Amer J Bot 91:125–138] Most important of timber pathogens; most species cause abnormal branching (witches' brooms) in hosts. Recent molecular studies support reunification of many western North American species under Arceuthobium campylopodum." ^[Jepson]

Non-local Species(??);

• Arceuthobium campylopodum - Western Dwarf Mistletoe

Key to the Species and Taxonomic Notes

• 1. Flowers unstalked or the female ones with stalks up to 1 mm long, usually in pairs at each node; stems over over 2 mm thick and at least 3 cm long; plants parasitic on many genera of Pinaceae.................Arceuthobium campylopodium
• 1. Flowers terminal on short lateral branches, the branches bearing the male flowers often more than 2 per node; stems scarcely as much as 2 mm thick and usually less than 3 cm long; plants parasitic on Pinus or Pseudotsuga.
• 2. Secondary branches of twigs lying in the same plane, thus flat and fanlike; stems scarcely 1 mm thick; plants parasitic on Pseudotsuga......................Arceuthobium douglasii
• 2. Secondary branches of twigs distinctly whorled, not fanlike; stems over 1 mm thick; plants parasitic on Pinus...............................Arceuthobium americanum ^[E-flora]

Lore

Mistletoe used to be something nice to eat, but the Coyote got mean with it & put it so as nobody can eat it. Tast’ú•t grows on dead trees, like a head of lettuce. [It's an old] Salmon River story. Coyote came upon girls picking mistletoe, it used to be something good to eat, & when the girls refused Coyote he got mad at them & said all right, I will turn what you are gathering then. And so, mistletoe has been no good to eat every since. [Harrington, 1942]
