Description:

The monotypic genus Dedeckera contains the single species Dedeckera eurekensis, a plant known by the common name July gold which is endemic to California. July gold flowers from May through August and is a member of the buckwheat family. It is a matting shrub which bears small fleshy leaves and tiny yellowish flowers (2-4 mm). It is a plant of the dry mountainous scrub, where it grows on gritty limestone cliffs. July gold is a rare plant, and its populations are scattered due to its specific niche habitat. It is also a poor reproducer; only about 1% of its flower ovules produce viable seed. No juvenile plants or seedlings currently known [CNPS, Calscape]
