Astragalus wingatanus, commonly known as the Fort Wingate milkvetch, is a species of flowering plant in the family Fabaceae. It is a perennial herb with white and purple flowers, and black or dark brown seeds.
The species is native to the deserts and dry shrublands of the south-western United States, and was described in 1883. Its conservation status is Secure.
Taxonomy
The species was described by Sereno Watson in 1883.[2]
The type locality is Glenwood Springs, Colorado.[3]
Distribution
Astragalus wingatanus is native to the deserts and dry shrublands of Arizona, Colorado, New Mexico, and Utah, in the western United States.[2] It grows on sandy hills, below cliffs, on open flats, and in oak thickets and pinyon–juniper woodlands. The species is present at elevations of 5,000–7,500 feet (1,500–2,300 m).[4]
Description
Astragalus wingatanus is a perennial herb.[5] It grows 30–35 centimetres (0.98–1.15 ft) high. The stems have white hairs.[3]
The leaves are 2.5–6.5 centimetres (0.98–2.56 in) long, and range in shape from linear-oblanceolate to narrowly elliptic, or sometimes oblong-elliptic.[4] The plant has five to seven leaflets. The lateral leaflets are 4–8 millimetres (0.16–0.31 in) long, and the terminal leaflet is 15–20 millimetres (0.59–0.79 in) long.[3]
The corolla is white, and has a greenish hue. The calyx is a 2.5–3.7 millimetres (0.098–0.146 in) long tube, with black or white hairs. The petals are white and purple.[3][4]
The seeds are black or dark brown, and pitted or wrinkled. The seeds are oblong to kidney-shaped, around 2.8–3.6 millimetres (0.11–0.14 in) long, and around 1.5 millimetres (0.059 in) wide.[3][4]
Ecology
The leaves host the mould Peronospora trifoliorum.[6]
