Eriogonum parvifolium
''Eriogonum parvifolium'' is a species in the Polygonaceae family that occurs on dune formations in the coastal area of Central and Southern California. This evergreen shrub grows to a height of 30 to 100 centimeters with a spread of approximately the same dimension.〔(''Eriogonum parvifolium'': Summary profile and photos )〕 This plant is an important host for a number of pollinating insects including certain endangered species. ''E. parvifolium'' occurs both on bluffs along the Pacific Ocean coast as well as Coastal Strand dunes formations, but is restricted to altitudes below 700 meters. In at least one instance within the Carbonera Creek watershed, it occurs farther inland in a Maritime Coast Range Ponderosa Pine forest.〔''Environmental Impact Report for the Scotts Valley Redeveopment Area'', Earth Metrics Incorporated, State of California Clearinghouse Report 7888 (1990)〕 This shrub is also known by the common names Dune buckwheat, Coast buckwheat, Cliff buckwheat, or Seacliff buckwheat.
==Description==
The thick cauline leaves are five to thirty millimeters in size and may be lanceolate to rounded.〔(''"Eriogonum parvifolium":Jepson Manual, University of California Press'' )〕 Alternatively leaves may be folded under, with the result of appearing more or less triangular; moreover they are smooth on the upper surfaces and woolly below. Foliage is green with reddish tinge, and the flowers white to pinkish or yellowish-green. The perianth measures 2.5 to 3.0 millimeters. This plant's glabrous fruits are 2.5 to 3.0 millimeters across.
