Gray's desert-parsley is one of twelve species of Lomatium
found in British Columbia. It is a tap-rooted perennial species with finely dissected blue-green leaves and the typical flat-topped flower cluster of this genus. Flowers are yellow. It is found in North America from BC south to New Mexico ((CO, ID, NM, NV, OR, UT, WA, WY), but in British Columbia it is restricted to the Gulf Islands, representing "a coastal outlier west of the cascades" (COSEWIC 2008). Like other Lomatium
species, it shows preference for stony ground and shallow soils, and, in BC, is found on "very steep or vertical, southwest-facing rock walls where the plants grow on narrow ledges, in cracks of the rock, and in small pockets of soil." (COSEWIC 2008). It is a spring-flowering (April in BC), summer dormant species. Lifespan is reported as 5-7 years (various sources). Gray's desert-parsley is one of the species collected by Lewis and Clark ("collected along the Columbia River perhaps at the mouth of Major Creek, Klickitat Co., Washington, on 14 Apr 1806") (Reveal 2001). The three collections for this species in the UBC Herbarium are from 1996, and all are from Saltspring Island.
