Calycadenia villosa
''Calycadenia villosa'' is an uncommon species of flowering plant in the daisy family known by the common name dwarf western rosinweed. It is endemic to central California, where it is known from a limited distribution in the Central Coast Ranges in Monterey County and San Luis Obispo County, with a few populations in Santa Barbara and western Fresno Counties.〔(Center for Plant Conservation )〕 There are perhaps 16 occurrences.〔(The Nature Conservancy )〕〔(Biota of North America Program 2014 county distribution map )〕〔(Calflora taxon report, University of California, ''Calycadenia villosa'' DC. dwarf calycadenia )〕
''Calycadenia villosa'' is an annual herb producing a very hairy erect stem approaching 40 centimeters (16 inches) in height. The leaves are linear (long and narrow) and up to 5 centimeters (2 inches) long. The inflorescence is made up of clusters of flower heads surrounded by gland-tipped bracts. Each flower head is a hairless bunch of small disc florets and 1 to 4 white to pink ray florets. Each ray floret has three lobes, the middle lobe being narrowest. The fruit is an achene; those developing from disc florets bear a pappus of scales.〔(Flora of North America, ''Calycadenia villosa'' )〕
