Distribution

Physocarpus monogynus occurs from northern Mexico and west Texas north to Montana and South Dakota and west to Nevada (Elmore 1976, USDA 2008). It grows on slopes, shaded by being in canyons or facing north, at altitudes of 1,700 to 3,000 meters (5,500 to 10,000 feet). The typical habitat, at least in the southern part of its range, is dominated by ponderosa pine and scrub oak (Elmore 1976).

Description
Main stem with peeling bark

The Physocarpus monogynus plant reaches 1.2 meters (4 feet) in height and somewhat more in width. The leaves are dull green above and paler below, with 3 to 5 doubly toothed lobes, so they suggest big currant (Ribes) leaves. The bark is brownish and shreds, revealing many layers, hence the name "ninebark" (Elmore 1976).

In May or June, mountain ninebark bears "rather lovely" white or rose-colored flowers, with five petals based in a cup-like structure. The flowers have one style, the meaning of "monogynus" (literally "one female part"). They turn red-brown and stay on the plant into the winter. The seed pods are inflated and covered with white hairs (Elmore 1976). The seeds are bean-shaped, about 2 mm long, bright shiny yellowish (USDA 2008).

Uses

Indians made a pain-relieving poultice by boiling the roots and placing them on the site while still warm.

Rocky Mountain goats eat the twigs when smaller plants are hidden under snow (Elmore 1976).

gollark: Quaternionic.
gollark: If Go is any guide, people will just get used to arbitrarily bad language features if it has *some* thing they want.
gollark: I'm sure *some* awful language does preemptive multithreading anyway.
gollark: Yes, runtimes do cooperative, not preemptive.
gollark: Oh, wait, sorry, I got that the wrong way round.
