Subspecies 2 (2 in the flora).

A usually tiny plant, Botrychium pallidum is separable from dwarfed and narrow sun forms of B. minganense by the peculiar, often folded pinnae and pale green to whitish color. It has been found growing with B. campestre, B. echo, B. hesperium, B. lunaria, B. matricariifolium, B. minganense, and B. spathulatum. Its small size may cause it to be overlooked. This is one of four moonwort species that commonly produce dense clusters of minute, spheric gemmae at the root bases.
Of conservation concern.
