Micromorphological and anatomical spine features of selected Escobaria species (Cactaceae)
Original language description
The article presents the results of a study of five species of Escobaria (E. missouriensis s. s., E. missouriensis subsp. navajoensis, E. abdita, E. hesteri s. s. and E. minima): their macro-morphology, the morphology of their spine surface and also theanatomy of their spines in cross-section. Of the five species, E. abdita stands out with its four-layered spine structure in cross-section. The spines of the other species show a two-layered structure. This study has helped to distinguish the new taxon E. abdita, discovered and described from the Mexican state of Coahuila, on the species level. The surface structure shows trichomes only in E. missouriensis s. l., whereas these are lacking in E. abdita and other species. The detected facts may be relevant to the genus taxonomy. The spine anatomy of this genus had not been investigated before.
