Arabis breweri. {+} BREWER'S ROCK-CRESS. Perennial. Bl Mar-Apr. Uncommon on dry rocky outcrops throughout, e.g. the Narrows, NE of Los Cruzeros, W end of Mt. Stakes Tr at ca 2740 ft, Robinson Mtn.


Arabis glabra. {++} TOWER-MUSTARD. Biennial or perennial. Bl Mar-May. Open shaded woods. Apparently uncommon; known only from the vicinity of Frog Lake, from N end of Mahoney Ridge, and from summit of Serpentine Road near Willson Peak.


Athysanus pusillus. {++} DWARF ATHYSANUS. SANDWEED. Annual. Bl Mar-Apr. Common in grassy and brushy places throughout.


*Barbarea verna. {+} EARLY WINTER CRESS. Biennial or perennial. Bl Mar-Jul. Common along streams, springs, & other wet places. Springs Tr, Madrone Soda Springs, Little Fk Coyote Ck, Poverty Flat, Middle Fk Coyote Ck on Thomas Addition, Rock House Cyn, E Fk Coyote Ck, Hoover Lake, Mississippi Ck, Pinto Ck, Robinson Ck, Lion Cyn, Hartman Ck, S Fk Orestimba Ck, N Fk Pacheco Ck. Native of Europe. The native Barbarea orthoceras has also been reported, but I've been unable to find any. All of the Barbarea I've seen appears to be the non-native species, to which it keys fairly well. I suspect that reports of the native species are based on misidentifications of the non-native.


*Brassica nigra. {+} BLACK MUSTARD. Annual. Bl Mar-Apr (& probably longer). Dry grassy slopes, roadsides, etc. Locally common, e.g. near Coit Camp, near Pacheco Camp, Kaiser-Aetna Rd SE of Burra Burra Pk. Native of Europe.

Common in field in side cyn below Kelly Lake; also just S of mouth of Robinson Ck, at Dowdy Ranch, near mouth of Hunting Hollow, and near the roadside spring along the Kaiser-Aetna Rd close to Bell Station. Native of Eurasia. Keys well to this species, but the manuals describe its maximum height as around 2½ feet tall. Many of the Coe plants are taller, some up to 4 feet high.
