Corolla tube formation in the primulaceae and ericales

Botanical Magazine, 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.

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.

Vesicular-Arbuscular Mycorrhizae in Hawaiian Ericales

American Journal of Botany, 1990
Vesicular-arbuscular mycorrhizae are reported for the first time in Vaccinium calycinum, V. dentatum and V. reticulatum (Ericaceae) and Styphelia tameiameiae (Epacridaceae). The coarse roots (>1.5 mm diam) of many specimens were densely colonized by VAM fungi, with up to 90% of the length of roots containing arbuscules, vesicles, coils, and internal ...

ERICALES REVISITED

TAXON, 1976
SummaryAttention is drawn to the similarity between two classifications of Ericaceae. The later of these is here held to be an extension with minor modifications of the earlier one, which was derived with the aid of a computer.

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 ...

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.

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.

Phylogeny of Theophrastaceae (Ericales s. lat.)

International Journal of Plant Sciences, 2003
Morphological traits and sequences from two chloroplast genes, ndhF and trnL‐F (intron, 3′ exon, and spacer), have been used to investigate relationships in the Ericalean family Theophrastaceae. A total evidence parsimony analysis shows that the herbaceous genus Samolus is sister to all other Theophrastaceae.

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.
