Blennosperma nanum is an annual plant in the daisy family native to California. Common names include glue-seed, common stickyseed, and yellow carpet.[2]

Description

[edit]

It is an annual with small yellow flower heads The heads are a paler yellow than many other daisy-like flowers, and the ring of stamens ooze a viscous white juice containing the pollen. The fruits are also carried in a gluey fluid. The Greek name for the genus means "slimy seed."[3]

Distribution

[edit]

The species is distributed throughout the lower elevations in California from Shasta County to San Diego County,[2] but nowhere is it particularly abundant. It is a resident of vernal pool floral communities. Glue-seed is often one of the first flowers to bloom as winter turns to spring.[3]

  • Blennosperma nanum var. robustum: the Point Reyes subspecies of the plant, sometimes called Point Reyes blennosperma, is very rare and is only found in that isolated area.
  • Blennosperma nanum var. nanum is much more common, and is sometimes called common blennosperma, yellow carpet, or meadow daisy.
