Vessel Grouping In Dicotyledon Wood, Sherwin Carlquist Jan 1984

Vessel Grouping In Dicotyledon Wood, Sherwin Carlquist

Aliso: A Journal of Systematic and Floristic Botany

A hitherto unappreciated correlation exists between nature of vessel grouping and nature of imperforate tracheary elements in wood of dicotyledons at large: families and genera with true tracheids (large fully bordered pits common on both radial and tangential walls) have solitary vessels. Presence of true tracheids as a subsidiary conductive system is hypothesized to render vessel grouping a superfluous adaptation. Vessel grouping does occur to various degrees in taxa with fiber-tracheids or libriform fibers; the degree of grouping is related to likelihood or seriousness of vessel failure by air embolisms because of either drought or frost. Grouping of vessels is …

Comparative Morphology Of Idiomyces And Its Possible Allies Diplomyces, Sandersoniomyces, Symplectromyces, And Tetratomyces (Ascomycetes: Laboulbeniales), Richard K. Benjamin Jan 1983

Comparative Morphology Of Idiomyces And Its Possible Allies Diplomyces, Sandersoniomyces, Symplectromyces, And Tetratomyces (Ascomycetes: Laboulbeniales), Richard K. Benjamin

Aliso: A Journal of Systematic and Floristic Botany

Pertinent stages of development of the receptacle, primary and secondary appendages, and perithecium of Idiomyces peyritschii are described and illustrated and comparison is made between this species and the type species of Diplomyces, Sandersoniomyces, Symplectromyces, and Teratomyces for which early stages of receptacular and appendage development also are described and illustrated. Possible close relationship of these genera with one another is examined in the light not only of morphological similarities and differences but also of host range. It is concluded that Diplomyces, Sandersoniomyces, Symplectromyces, and Teratomyces do indeed constitute a closely allied group of genera. However, the gap between this …

Laboubeniales On Semiaquatic Hemiptera. Iv. Addenda To Prolixandromyces, Richard K. Benjamin Jan 1981

Laboubeniales On Semiaquatic Hemiptera. Iv. Addenda To Prolixandromyces, Richard K. Benjamin

Aliso: A Journal of Systematic and Floristic Botany

Three new species of Prolixandromyces (Ascomycetes: Laboulbeniales), all parasites on Velia (Hemiptera: Veliidae), are described and illustrated: P. lingulatus, P. rhinoceralis, and P. tenuis. A key to the five species presently known is given. The two species described originally, P. veliae and P. corniculatus, were found in Michoacan in southern Mexico; the range of P. corniculatus is extended to El Salvador. Prolixandromyces lingulatus and P. rhinoceralis were collected in Nicaragua and P. tenuis m Costa Rica.
