Circumscription of the south American moonwort botrychium (ophioglossaceae)

The genus Botrychium (Ophioglossaceae) is comprised of about 30 widely distributed species. Because of their small size and few, yet variable, morphological characters, many questionable taxa have been described over the years. Since its description in 1906, B. dusenii has been treated as both a d...

Because of their small size and few, yet variable, morphological characters, many questionable taxa have been described over the years. Since its description in 1906, B. dusenii has been treated as both a distinct species and variously divided into four taxa: B. lunaria var. dusenii, B. lunaria var. typicum, B. lunaria var. antarctica, and B. ramosum var. patagonicum (B. matricariaefolium subsp. patagonicum). The aim of this study is to evaluate the validity of these taxa using spore wall sculpture, spore size, allelic composition employing enzyme electrophoresis, and morphological characters. We conclude that only one species of Botrychium occurs in southern South America and recognize this as B. dusenii, a species distinct from B. lunaria. Spore size and results of enzyme electrophoresis suggest that B. dusenii is an allotetraploid derived through hybridization between a diploid member of the B. lunaria complex and a diploid member of the B. campestre complex. We provide information about habitat, distribution, and full exsiccate citations. 2022-05-26T14:16:24Z 2022-05-26T14:16:24Z 2017 Artículo Meza Torres, Esteba I., et. al., 2017.
