Astragalus hypoxylus is a rare species of flowering plant in the legume family known by the common name Huachuca milkvetch, or Huachuca Mountain milkvetch. It is endemic to Arizona in the United States, where it is known only from the Patagonia and Huachuca Mountains.[1] There are three populations.[2]
Description
This small perennial herb forms a patch on the ground no more than about 10 cm (3.9 in) wide and 3 to 4 cm (1.2 to 1.6 in) tall. It grows from a fibrous
monotypic genus all its own.[1]
This plant grows in woodlands dominated by
Mexican pinyon (Pinus discolor). The substrate is a gravelly soil rich in limestone and metamorphic rock.[1][3]
