Taxonomic Comments
Baldwin (1999) published the new combination Anisocarpus scabridus for the species treated as Raillardiopsis scabrida by Kartesz (1994, 1999). Anisocarpus is reinstated to better reflect phylogenetic relationships (Baldwin 1999). Flora of North America Editorial Committee (2006) also treats this species as Anisocarpus scabridus.

Rank Reasons
Anisocarpus scabridus is restricted to northern California where it occurs on to metamorphic scree slopes at high elevations. Nineteen occurrences are known. Threats include erosion, recreation, and development.
Range Extent Comments
Anisocarpus scabridus is endemic to northern California, mostly in the High North Coast Ranges (Baldwin et al. 2012; Consortium of California Herbaria 2020).
Occurrences Comments
There are 19 occurrences in California, 12 of which were last observed over 15 years ago (California Natural Diversity Database 2020).
Threat Impact Comments
Threats include erosion, off-road vehicles, trampling, development, and roads (CNDDB 2020).
