Discusión taxonómica
It is distinct from B. minganense by the supernumery sporangia, and the larger plant size. Confusion about the identity of this plant is attested to by its previous identifications, namely Botrychium lunaria var. minganense and B. matricariifolium. The three excellent plants at VT are clearly distinct from any previously described species of Botrychium. It is no surprise that the elevation of collection was 11,500 ft. In 1991, Wagner visited the volcano in the hope of rediscovering this species. Although there were a number of seemingly appropriate habitats, he failed to find it. However, it is entirely possible that the season was wrong, or that droughts had kept the leaves from appearing. This species should be sought again at Volcán Toluca, as well as in similar sites elsewhere.
Botrychium tolucaense resembles B. X watertonense W. H. Wagner of western Alberta, Canada, in the presence of sporangia along the pinna margins on the otherwise sterile blade.
