A New Species of Linanthus (Polemoniaceae) from San Bernardino County, California

Abstract

Linanthus bernardinus is described as new from San Bernardino County, California. It is morphologically similar to L. killipii and L. orcuttii subsp. pacificus but differs from plants of these taxa in height, corolla length, seed morphology, and habitat. Linanthus bernardinus can be found growing in vernally moist areas within Joshua tree woodland, often in shallow depressions, or on gentle slopes, in decomposed granite sand that is surrounded by large granite boulder fields.
