Studies of Floral Morphology in the Ericales. V. Organography and Vascular Anatomy in Several United States Species of the Vacciniaceae
- BiologyBotanical Gazette
The organography and vascular anatomy of the following United States species of Gaylussacia and Vaccinium are described in whole or in part and members of the Vacciniaceae studied are pentacyclic, actinomorphic, and perfect.
The Floral Morphology of Clethra alnifolia with some Notes on C. acuminata and C. arborea. Contributions from the Hull Botanical Laboratory 632
- Environmental ScienceBotanical Gazette
A comparison of the characteristics of the Clethraceae, as exemplified by the three species studied, with those of other groups in the Ericales shows that the family is not so primitive with respect to the vascular anatomy of the flower as it is with respectto certain of its other morphological features.
Preforming floral primordia converge on a narrow range of stages at dormancy despite multiple effects of temperature on development.
- MedicineThe New phytologist
There may be strong endogenous flower level controls over development, particularly the stage at which morphogenesis ceases prior to dormancy, however, the strength of such internal controls in the face of continuing temperature extremes under a changing climate is unclear.
Early floral development and androecium organization in the sarracenioid clade (Actinidiaceae, Roridulaceae and Sarraceniaceae) of Ericales
The early floral development of Actinidia, sarracenioids and Roridula gorgonias and Heliamphora nutans was studied comparatively using scanning electron microscopy, further emphasizing the highly variable patterns of androecium development in the order.
VII. EMBRYOLOGY IN THE PHYLLODOCEAE1
Various aspects of embryology have been described for 16 taxa representing six genera of the tribe Phyllodoceae (subfamily Rhododendroideae, family Ericaceae), including meiosis in the microspore mother cells, cytokinesis by furrowing is simultaneous, and development of the endosperm is cellular and precedes that of the embryo.
Glandulocalyx upatoiensis, a fossil flower of Ericales (Actinidiaceae/Clethraceae) from the Late Cretaceous (Santonian) of Georgia, USA.
- GeographyAnnals of botany
Comparison with extant taxa provides clear evidence for a relationship with core Ericales comprised of the extant families Actinidiaceae, Roridulaceae, Sarraceniaceae, Clethraceae, Cyrillaceae and Ericaceae.
Pollen-ovule ratios in seven species of Vaccinium (Ericaceae) and stamen structure in Vaccinium myrtilloides and Vaccinium vitis-idaea11This article is part of a Special Issue entitled “Pollination biology research in Canada: Perspectives on a mutualism at different scales”.
- Environmental Science
Pollen-ovule (P/O) ratios were determined for five Vaccinium species (Ericaceae) native to eastern Canada and are indicative of facultative autogamy to facultative xenogamy.
Phylogenetic classification of Ericaceae: Molecular and morphological evidence
- BiologyThe Botanical Review
A new classification of Ericaceae is presented based on phylogenetic analyses of nuclear and chloroplast DNA sequence data, morphology, anatomy, and embryology, and three new taxa are described: Oligarrheneae, Richeeae, and Cosmelieae (all within Styphelioideae).
