Wood Anatomy And Relationships Of Santalaceae I. Acanthosyris, Jodina, And Myoschilos, Carlos Alejandro Norverto
Wood Anatomy And Relationships Of Santalaceae I. Acanthosyris, Jodina, And Myoschilos, Carlos Alejandro Norverto
Aliso: A Journal of Systematic and Floristic Botany
Study of the wood of Acanthosyris, Jodina, and Myoschilos confirmed a close relationship between Santalaceae and Olacaceae. Features important for defining the three genera and for determining relationships between them and with Schoepfia, which belongs to Olacaceae, are reported for the first time: vestured vessel walls, unilaterally compound pits, perforated ray cells, and druses.

Podostemum ceratophyllum contains γ-mangostin and its 6-glucoside. The aglycone is also present in Marathrum, Oserya, and Vanroyenella, but is absent from Tristicha. Anthocyanins were identified from all genera, but no additional fiavonoids were detected. Condensed and hydrolyzable tannins, iridoids, cyanogenic glycosides, and alkaloids were lacking in all Podostemaceae examined. Phytochemical constituents do not clarify the uncertain systematic affinity ofPodostemaceae, but emphasize the generally accepted taxonomic isolation of this family.
A Review Of The Classification Of The Genus Hydrastis (Ranunculaceae), Carl S. Keener
A Review Of The Classification Of The Genus Hydrastis (Ranunculaceae), Carl S. Keener
Aliso: A Journal of Systematic and Floristic Botany
The genus Hydrastis has been variously classified as a monotypic taxon in the Ranunculaceae, the Berberidaceae, the Glaucidiaceae, or its own monogeneric family, the Hydrastidaceae. The objectives of this paper were 1) to review the previous classifications of Hydrastis and 2) to critique a recent paper by Tobe and Keating reevaluating the classification of the genus based on comparative morphological and anatomical studies. One conclusion of this review was that Tobe and Keating overlooked certain important papers which might have substantially altered their conclusions, viz., that Hydrastis is sufficiently distinct from the other genera of the Ranunculaceae to warrant a …

Quantitative and qualitative data were offered for 30 taxa of Meliosma and one species each of Ophiocaryon and Sabia; qualitative data were available for additional species of Meliosma and Sabia. For a small family restricted to mesic sites, Sabiaceae had a wide range of wood anatomical expressions (e.g., long scalariform to simple perforation plates; heterocellular to homocellular multiseriate rays; tracheids, fiber-tracheids, or libriform fibers as imperforate tracheary elements; presence or absence of silica bodies and calcium oxalate crystals in rays). Growth ring type, vessel diameter, vessel density, and vessel element length were sensitively related to ecology, but to …
Laboulbeniales On Semiaquatic Heteroptera. Vi. The Genus Tavaresiella, Richard K. Benjamin
Laboulbeniales On Semiaquatic Heteroptera. Vi. The Genus Tavaresiella, Richard K. Benjamin
Aliso: A Journal of Systematic and Floristic Botany
Majewski's original circumscriptions of Tavaresiella (Laboulbeniales; Laboulbeniaceae; Stigmatomycetinae) and its type species, T. hebri, were emended in this study of the genus. In addition, three new species were described, T. majewskii, T. polhemi, and T. santamariae. These, like the type species, occurred on true bugs of the family Hebridae (Heteroptera). A key to the species was provided, and ali were described and illustrated with line drawings and photographs. Aspects of ascomatic structure and development were summarized, and the genus was compared with other genera of the subtribe having similar characteristics.
