Discusión taxonómica
Botrychium socorrense closely resembles specimens of B. schaffneri, the former differing in its extremely robust habit (40–60 cm tall vs. mostly 15–35 cm) and strongly overlapping blade divisions. It is also close to B. multifidum (S. G. Gmel.) Rupr. of California (sometimes called B. silaifolium C. Presl), resembling it in the large, floppy frond divisions. A
