Note
|
Draba matthioloides subsp. saundersii is indistinguishable from subsp. matthioloides in nearly all aspects of habit, leaf, flower, and fruit. It is readily distinguished from the type subspecies by its purple flowers, glabrous fruits, and shorter (2-4 mm) styles. Subspecies matthioloides has orange to yellow flowers, tomentose fruits, and styles (4-)5-10 mm long. Because of the taxonomic significance of flower color in Draba, one might be tempted to recognize these two taxa as separate species. Only five specimens of the two subspecies were available for study, however, and in the absence of further material, the overall variation in these characters cannot be fully understood.
