Phylogeny, character evolution, and classification of Sapotaceae (Ericales)

Cladistics, 2005
AbstractWe present the first cladistic study of the largely tropical family Sapotaceae based on both morphological and molecular data. The data were analyzed with standard parsimony and parsimony jackknife algorithms using equally and successive weighted characters.

Unisexual Flowers in the Ericales

Nature, 1957
THE flowers of the Epacridaceae have been described as hermaphrodite1,2 or hermaphrodite, rarely dioecious3, but in the latter case no examples of dioecy are quoted. The following notes concerning species previously described as hermaphrodite indicate that unisexual flowers may be not uncommon in this family.

Impatiens leptocarpa (Ericales: Balsaminaceae): A New Record for the Flora of Bhutan

Feddes Repertorium
Impatiens leptocarpa , belonging to Impatiens sect. Racemosae , is reported as a new addition to the flora of Bhutan. Impatiens leptocarpa can be distinguished from other related species by its four lateral sepals, lanceolate upper pair of ...

Mycorrhiza in the New Zealand Ericales

Australian Journal of Botany, 1961
The New Zealand species of the Ericaceae and Epacridaceae examined possessed mycorrhizas anatomically similar to those of Calluna and Vaccinium. The endophyte of Pernettya macrostigma was isolated and successfully back inoculated into the host, under controlled conditions. Its taxonomic identity was uncertain because of its reproductive sterility.

The biology of mycorrhiza in the Ericales

Canadian Journal of Botany, 1983
The types of mycorrhizal structure seen in the Ericaceae and in the closely related families Pyrolaceae and Monotropaceae are reviewed briefly. Ericoid, arbutoid, and monotropoid mycorrhizas are characterized. The processes of infection and of establishment of the mature ericoid mycorrhizal association are discussed from the structural ...

THE DEVELOPMENT OF SEEDS IN CERTAIN ERICALES

American Journal of Botany, 1933
The ovule of Monotropa Hypopitys is a classic subject of study. It seems first to have been described by Mffller (I847). The development of seeds in this species was described in detail by Koch (I882). Stevens (i9ii) published the first accurate description of the developnment of seed in a species of Ericaceae, Epigaea repens.

Fossil Ericales from the Upper Cretaceous of New Jersey

International Journal of Plant Sciences, 2013
Premise of research. Fossil flowers and other related organs of Turonian age from Cretaceous Atlantic Coastal Plain deposits in northern New Jersey are remarkable in their degree of preservation and document important events in the radiation of eudicot angiosperms relatively early in their history.Methodology.

Corolla tube formation in the primulaceae and ericales

The Botanical Magazine Tokyo, 1983
Corolla tube formation was investigated anatomically for 13 species of the Primulaceae and Ericales. In the Primulaceae, petal primordia appear after the stamen initiation. The lower portion of the corolla tube, the portion under the stamen insertion, is derived from the ring-like structure formed immediately after the stamen initiation.

Origin, diversification, and evolution of Samolus valerandi (Samolaceae, Ericales)

Plant Systematics and Evolution, 2012
The almost cosmopolitan distribution of Samolus valerandi is unique in the genus Samolus L. (Samolaceae), which also includes 12–15 taxa with distributions restricted to smaller areas of the Southern Hemisphere. Recent molecular phylogenetic studies based on chloroplast and nuclear DNA sequences showed that the widespread S.

Early floral development and androecium organization in Fouquieriaceae (Ericales)

Plant Systematics and Evolution, 2005
Early floral development with focus on the androecium was studied with the help of scanning electron microscopy and serial microtome sectioning in Fouquieria columnaris and F. splendens. Perianth organs appear in a spiral pattern on the floral apex. The spiral may be a clockwise or anti-clockwise.
