Description and Life
Applegate's milk-vetch is a slender perennial in the pea family
(Fabaceae) with stems 3-4 dm (12-16 in) long. The leaves are
typically 3.5-7 cm (1.4-2.8 in) long with 7-11 leaflets. The
petals are whitish, measuring up to 7 mm (0.3 in) long. The
tip of the keel is faintly lilac- tinged. The fruit is a pod
and is widely spreading or declined. Dehiscence (pod opening
at maturity) starts at the top of the pod and continues downward.
Applegate's milkvetch typically flowers from June to early August.
Applegate's milk-vetch occurs in flat-lying, seasonally moist,
strongly alkaline soils dominated by greasewood (Sarcobatus
vermiculatus) with sparse, native bunch grasses and patches
of bare soil.

This species is historically known from only four sites, near
the city of Klamath Falls in Klamath County, Oregon, approximately
1250 m (4,100 ft) above sea level. The largest population is located
near Ewauna Lake in Klamath Falls; a significant portion of the
site this population occurs on is owned by The Nature Conservancy.
