Veiny monardella is an annual herb to 0.3 meters tall with purple flowers from May to July. It's known only from six populations in Butte County, in northern California. It was thought to be extinct until its rediscovery in 1992, having been last documented in 1935 in Tuolumne County. The area where veiny monardella was rediscovered, in May 1992, was burned in a wildfire in September 1992, followed by two rainstorms. Four weeks after the fire, abundant seedlings were observed by Barbara Castro of the U.S. Forest Service (Castro and Janeway 1993).
Distribution & Occurrence
Flat to gently sloping terrain in the annual grassland component of a foothill woodland plant community, from 60 to 410 meters elevation. This species occurs only in lenses of dark gray, deeply cracking clay within alluvium derived from Tuscan Mudflow rock outcrops.
|The six populations vary in number of plants each year from less than 10 to 1000 (Castro and Janeway 1993).|
