In my opinion» the material referred to as A* lentiginosus var.
micans is qitiite distinct and confined to Eureka Valley Dunes* Plants
which I tagged over three years ago continue to flourish to date and are
summer active (possessing foliage). The inflorescence and flower of
micans tend?.® to be more robust» although the measurements presented
are not the result of intensive sampling and analysis* Coloration
of the corolla and pods before drying is very different in var# micans
compared to the material here assigned to var. variabilis (see photos).
It is clear that micans is probably a derivative of the variabilis
complex which is generally widespread both on and off dunes.
