Species Profile
Radiola linoides is the sole species in the Radiola genus, a monotypic genus of flowering plants belonging to the family Linaceae. It has the common names of 'allseed' and 'flaxseed'. It has a very short stem which is repeatedly subdivided, with a pair of very small leaves and a single white flower at each fork and at the end of the branches. It has leaves which are opposite arranged, oval and sessile.
Allseed (Radiola linoides) is declining primarily due to habitat loss and degradation of its specialized wetland environments. The species is particularly vulnerable to changes in hydrology, agricultural intensification, and development pressure on the temporary pools and damp sandy areas it requires for reproduction.
