Oxytropis parryi
Fabaceae (Pea Family) Subalpine, alpine. Rocky openings, tundra. Summer. Oxytropis parryi grows from one to four inches tall on high altitude ridge tops and tundra. Here it is pictured on a rocky knoll at 10,800 feet. Oxytropis parryi is difficult at first to find in such an area because the plant is so minute, but when one learns to walk slowly, head down, looking for the characteristic sage green hairy leaves, one is quickly rewarded with numerous sightings of the plant. Asa Gray named this plant in 1884 from a specimen collected by Charles Parry in the mountains above Taos, New Mexico, in 1867. "Oxytropis" is Latin for "sharp keel" and refers to the abruptly pointed tip of the keel petal, a characteristic that separates this genus of Fabaceae from two other prominent Fabaceae genera, Astragalus and Hedysarum. Charles Parry was a highly respected and prolific collector of plants in Colorado and other areas of the Southwest. (Click for more biographical information). |

Oxytropis parryi Fabaceae (Pea Family) Subalpine, alpine. Rocky openings, tundra. Summer. Flowers are minute, erect, and typically open no more than the one on the left. The flower on the right is fading to inky blues. Black hairs are short and straight; white hairs are long, twisted, and often plumose (barbed). Welsh theorizes that the "flowers are cleistogamous [self-fertilizing, without opening]".
