New Species Of Scutellaria (Lamiaceae) From The Chihuahuan Desert Region, James Henrickson Jan 1990

New Species Of Scutellaria (Lamiaceae) From The Chihuahuan Desert Region, James Henrickson

Aliso: A Journal of Systematic and Floristic Botany

Three new species of Scutellaria are described from the Chihuahuan Desert Region of Mexico: S. hintoniorum from western Nuevo León, S. wendtii from eastern Chihuahua, and S. carmenensis from northern Coahuila.


Achene Microstructure In Eriophorum L. (Cyperaceae): Systematic Implications And Paleobotanical Applications, Gordon C. Tucker, Norton G. Miller Jan 1990

Achene Microstructure In Eriophorum L. (Cyperaceae): Systematic Implications And Paleobotanical Applications, Gordon C. Tucker, Norton G. Miller

Gordon C. Tucker

Silica bodies in the outer cells of the achene epidermis in 17 species of Eriophorum-and nine species of Scirpus, some of which have been placed in Eriophorum, were revealed by sonication and/or acetolysis and examined by scanning electron microscopy. A silica body consists of a basal platform, one or more large elevated protuberances, and sometimes smaller satellite protuberances. Individual species differ in the number of protuberances, the presence/absence of satellites, the texture of the platform, and the occurrence of nodules on the larger protuberances. These features, combined with achene shape and characteristics of the anticlinal walls of the epidermal cells …
