Blepharizonia

''Blepharizonia'' is a genus of flowering plants in the aster family, Asteraceae.〔(Greene, Edward Lee. 1885. Bulletin of the California Academy of Sciences 1(4D): 279 ) in English〕 There are two species, both endemic to California.〔(''Blepharizonia''. ) Flora of North America.〕 They are known generally as big tarweeds.〔(''Blepharizonia''. ) The Jepson Manual eFlora 2013.〕〔Baldwin, B. G., et al. (2001). (A biosystematic and phylogenetic assessment of sympatric taxa in ''Blepharizonia'' (Compositae-Madiinae). ) ''Systematic Botany'' 26(1), 184-94.〕
The genus long included only the single species ''B. plumosa'', which was divided into two subspecies. Studies of the plant indicated that the subspecies had low interfertility, rarely interbreeding when growing together.〔 They were also evolutionarily divergent〔 and had significant morphological and ecological distinctions.〔(''Blepharizonia laxa''. ) Flora of North America.〕 One of the subspecies was elevated to species status and is now usually treated as ''B. laxa''.〔
==Description==
These are annual herbs varying in height from 10 centimeters (4 inches) to over 1.8 meters (6 feet). They are strongly scented. The leaves are oppositely arranged near the base of the stem, and alternately arranged along most of the plant. They are linear, lance-shaped, or narrowly spatula-shaped, and sometimes toothed. The herbage is hairy to bristly and often glandular. The flower heads are often borne in wide arrays or spikelike inflorescences; ''B. laxa'' may have solitary heads. The hairy, glandular phyllaries grow close to the ray florets and can remain attached to the fruits they bear. The deeply lobed ray florets are usually whitish, often with red or purple nerves along the undersides. They are up to a centimeter long or longer. There are few to many whitish or purplish disc florets with purple anthers. The fruit is a ribbed cypsela, sometimes with a pappus of scales.〔〔
