The Streptanthus morrisonii complex is a six-taxon group of closely related serpentine rock outcrop endemics from Lake, Napa, and Sonoma counties of California, USA. Two new subspecies ( S . morrisonii subsp. kruckebergii and S. brachiatus subsp. hoffmanii ) from Lake County, California, are described. The relationship of these taxa to others in the section is reviewed and descriptions and a key are provided. Floristic surveys of serpentine rock outcrops conducted for environmental impact… 
The rare, serpentine endemic Streptanthus morrisonii (Brassicaceae) species complex, revisited using isozyme analysis
TLDR
Isozyme analysis of this little-studied complex supports the delineation of two species, S. morrisonii and S. brachiatus, but is at odds with the treatment of two subspecies based on morphology.
A NEW JEWELFLOWER (STREPTANTHUS, BRASSICACEAE) FROM MARIN COUNTY, CALIFORNIA, USA
TLDR
Floral morphology and other characters indicate that this taxon is most closely related to the S. glandulosus complex, but the bracted inflorescence is unlike that found in any other member of that complex.
A NEW SPECIES OF STREPTANTHUS (BRASSICACEAE) FROM THREE PEAKS IN LAKE COUNTY, CALIFORNIA
TLDR
Morphological and allozyme data indicate that this taxon is related to the S. morrisonii complex, a newly described species inhabiting serpentine rock outcrops in the Three Peaks area in Lake County, California.
