An Expanded Circumscription Of Bouteloua (Gramineae: Choridoideae): New Combinations And Names, J. Travis Columbus
An Expanded Circumscription Of Bouteloua (Gramineae: Choridoideae): New Combinations And Names, J. Travis Columbus
Aliso: A Journal of Systematic and Floristic Botany
Cladistic analysis of nuclear ribosomal and chloroplast DNA sequences has revealed that the New World grass genus Bouteloua (Chloridoideae) is not monophyletic. Indeed, some species of Bouteloua are more closely related to species in other genera than to congeners. The problem was dealt with by expanding the circumscription of Bouteloua to include species formerly positioned in the satellite genera Buchloe (1 species), Buchlomimus/em> (1), Cathestecum/em> (4), Cyclostachya/em> (1), Griffithsochloa (1), Opizia (2), Pentarrhaphis (3), Pringleochloa (1), and Soderstromia(1). Thirteen new combinations and names were necessary. As here circumscribed, Bouteloua is monophyletic and comprises 57 species.

Aliso: A Journal of Systematic and Floristic Botany
A new genus of Laboulbeniales (Laboulbeniaceae: Stigmatomycetinae), Monandromyces, was described. Its type species, M. hemipteralis, was based on Autophagomyces hemipteralis. The latter, which parasitizes a riparian bug, a species of Microvelia (Heteroptera: Veliidae), was characterized by Roland Thaxter in 1931. Ten new species of Monandromyces- taken from members of three genera of Veliidae-were described as follows: M. australis, M. falcatus, M. polhemorum, M. protuberans, M. tenuistipitis, and M. umbonatus (on Microvelia spp.); M. neoalardi (on Neoalardus sp.); and M. elongates, M. longispinae, and M. pseudoveliae (on Pseudovelia spp.).
