Deinandra fasciculata (syn: Hemizonia fasciculata), known by the common names clustered tarweed[1] and fascicled spikeweed,[2] is a species of flowering plant in the daisy family native to western North America. [3]
Range
Deinandra fasciculata is native to Baja California and California (primarily from San Diego County to Monterey County, including several of the Channel Islands; Calflora reports a few collections from the San Francisco Bay area, but these are from urban areas and probably represent cultivated specimens).[4] It is a common member of coastal grassland habitats in the California chaparral and woodlands ecoregion and other habitats.[3]
Description
Deinandra fasciculata is a thin-stemmed branched annual herb growing erect up to 100 cm (40 inches) in height. The upper leaves are narrow, about 1 centimeter long nested against the stem (more like short needles than leaves). The lower leaves are much bigger, up to 15 centimeters (6 inches) long.[5]
Each flower head has a center of six yellowish disc florets with black stamens surrounded by five yellow ray florets. The ray florets generally have three teeth, the central tooth being the smallest.[3]
In this genus the disk flowers are actually big enough to be seen as tiny flowers to the naked eye.
