Notes:

Hairy Rockcress, Arabis hirsuta var. glabrata

Family: Brassicaceae - MUSTARD FAMILY
Genus: Arabis is Greek for 'mustard' or 'cress'
Species: hirsuta means 'covered with hair'
The family was formerly named Cruciferae in reference to the crosslike formation of the four petals. This is a large family and unfortunately the photos here do not present enough detail for an accuarate identification. However, the white flower would typically have four petals and six stamens as shown here. Stems grow to 3' (1 m) in height with unstalked lance-shaped leaves which clasp the stem also descernable in the trail view. Not common, found in open gravelly from 2500' - 5000' elevation. (ref. Biek, Pojar)
