Yuccas (Agavaceae) Of The International Four Corners: Southwestern Usa And Northwestern Mexico, Lee W. Lenz, Michael A. Hanson Jan 2000

Yuccas (Agavaceae) Of The International Four Corners: Southwestern Usa And Northwestern Mexico, Lee W. Lenz, Michael A. Hanson

Aliso: A Journal of Systematic and Floristic Botany

Yuccas (Yucca, Agavaceae) are an easily recognizable constituent of the vegetation of the International Four Corners; an area made up of portions of Arizona, New Mexico, Sonora and Chihuahua. We recognize three species as native to the region, Yucca baccata, Y. elata and Y. madrensis, together with interspecific hybrids, and document for the first time naturally occurring intersectional hybridization between baccate-fruited (sect. Yucca) and capsular-fruited (sect. Chaenocarpa) species. We examine the reproductive barriers to hybridization operating within the genus, i.e., spatial, temporal and ethological, and we consider circumstances that may have been responsible for the production and …

Autophagomyces, Bordea, And A New Genus, Rossiomyces, (Laboulbeniales), Richard K. Benjamin

Aliso: A Journal of Systematic and Floristic Botany

A revision of Autophagomyces (Laboulbeniales) was made based on a comparative morphological study of new collections and 16 species included in the genus by Thaxter in the final volume of his monograph published in 1931 and by others more recently. The concept of Autophagomyces (species on Anthicidae, Phalacridae, and Scapidiidae [Coleoptera]) was narrowed and comprises 12 species, four of them new, i.e., A. hammondii, A. mexicanus, A. protuberans, and A. ramosus. The genus Bordea (species on Pselaphinae, Staphylinidae [Coleopteraj), which had been included in Autophagomyces by Thaxter, was reinstated and comprises 14 species, seven new, i.e., …
