Genetic analyses of the lanceolatum clade in genus Botrychium supports description a new diploid species, rubellum. It differs genetically, morphologically, and geographically from B. lanceolatum, which it is segregated, angustisegmentum. rubellum differentiated by red coloration common stalk, upswept basal pinnae, basiscopic pinnules much longer than acroscopic pinnules, spores larger other two genetic identities reflecting percent shared alleles. currently known to occur western North America southern Rocky Mountains Alaska, Yukon Territory, disjunctively Greenland.

Botrychium farrarii is described as a new species from the Bighorn Mountains of Wyoming, U.S.A. Based on allozyme patterns and chloroplast nuclear sequence data, it inferred to be diploid maternal (i.e., donor) parent three allotetraploids, B. furculatum, minganense, paradoxum, with which shares similar morphological traits. closely related campestre sensu lato, differs primarily by having longer trophophore sporophore stalks. A key morphologically-similar presented. At this time, documented few individuals four small, montane forest openings roadsides in close proximity within single watershed. Its full geographic range habitat preferences remain unknown, we hope paper will spur discovery additional populations. Until known more abundant, would prudent manage each site maintain population viability, including avoidance actions that could adversely impact plant persistence or suitability.
