Acer glabrum is a species of

Washington, Oregon, Idaho, Montana and Colorado to California, Arizona, Utah, and New Mexico.[2]

Description

Acer glabrum is a small

leaves are 2–13 cm (3⁄4–5 in) broad, three-lobed (rarely five-lobed),[3] variable in the depth of lobing, occasionally so deeply lobed as to be divided into three leaflets; the lobes have an acute apex and a coarsely serrated margin. The flowers are produced in corymbs of five to ten, yellowish-green, at the same time as the new leaves in spring. The fruit is a samara or winged seed, which develops in fused pairs at an angle of less than 45° when mature, though some varieties spread out to 90°.[3][4][5]

Varieties

There are four to six varieties, some of them treated by some authors at the higher rank of subspecies:[2][5][6]

  • Acer glabrum var. glabrum (syn. subsp. glabrum; Rocky Mountain maple)– Rocky Mountains, Montana to New Mexico
  • Acer glabrum var. diffusum (Greene) Smiley (syn. subsp. diffusum (Greene) A.E.Murray; Rocky Mountain maple) – eastern California, Nevada, Utah
  • Acer glabrum var. douglasii (Hook.) Dippel (syn. subsp. douglasii (Hook.) Wesm.; Douglas maple, also incorrectly vine maple[7]) – Alaska south to Washington and Idaho
  • Acer glabrum var. greenei Keller (Greene's maple) – endemic-central California
  • Acer glabrum var. neomexicanum (Greene) Kearney & Peebles (syn. subsp. neomexicanum (Greene) A.E.Murray; New Mexico maple) – New Mexico
  • Acer glabrum var. torreyi (Greene) Smiley (syn. subsp. torreyi (Greene) A.E.Murray; Torrey maple) – endemic-Northern California

Distribution and habitat

Acer glabrum is plentiful in many parts of the

quaking aspen.[8] It can be found in dry rocky areas.[3]

Ecology

It tends to be found in brush fields arising from fire-disturbed sites. Conifers tend to replace it in well-forested areas.[3] The foliage is browsed by game animals (especially deer and elk in winter), cattle, and sheep.[3][9]

Uses

Native Americans utilized the strong stems for snowshoe frames, bows, and other applications.[3] Some Plateau Indian tribes drink an infusion of Douglas maple as a treatment for diarrhea.[10] Ramah Navajo use an infusion of the glabrum variety for swellings, and also as a "life medicine", or panacea.[11][12]
