The pollen morphology of six species ofKeiskea and three representative taxa ofCollinsonia was studied in detail using LM, SEM, and TEM. In both genera, pollen grains are monad, hexa-colpate, and mostly medium in size [P = 28.0 to 37.0 μm, E = 24.3 to 30.7 μm (Keiskea); P = 30.0 to 45.0 μm, E = 26.0 to 39.0 μm (Collinsonia)]. Polar outlines are of circular or ellipsoid form. Shapes range from primarily oblate-spheroidal to prolate-spheroidal to subprolate, and rarely prolate in the equatorial… 
Systematic implications of pollen morphology in Elsholtzia (Elsholtzieae-Lamiaceae)
Pollen morphology of 18 species representing all three currently recognized sections of the genus Elsholtzia was investigated in detail using light, scanning electron and transmission electron microscopy, showing a wide range of morphological variation among species.
Pollen morphology of the East Asiatic genus Chelonopsis (Lamioideae: Lamiaceae) and allied genera, with reference to taxonomic implications and potential pollination ecology
Pollen grains of 15 taxa of the genus Chelonopsis and 6 species of the closely related genera Bostrychanthera and Gomphostemma were examined by light and scanning electron microscopy and the pollen morphology of 18 taxa was studied for the first time.
Comparative pollen morphology of Glechoma and Marmoritis (Nepetinae, Lamiaceae)
The results of Glechoma and Marmoritis reveal rather similar pollen morphological features, however, fine details of sexine ornamentation are characteristic to differentiate the pollen taxa.
Resolving the phylogenetic position of Ombrocharis (Lamiaceae), with reference to the molecular phylogeny of tribe Elsholtzieae
This study represents both the most comprehensive phylogenetic analysis of Elsholtzieae to date and the only study to include all genera of El sholtzia, and there is weak support for Elsh Holtzieae as sister to the rest of Nepetoideae.
Molecular phylogenetics and biogeography of the mint tribe Elsholtzieae (Nepetoideae, Lamiaceae), with an emphasis on its diversification in East Asia
These findings highlight the important roles of the uplifts of the Qinghai-Tibetan Plateau (QTP) and climate changes from Middle Miocene onwards in promoting species diversification of Elsholtzieae.
Primary identifications and palynological observations of Perilla in China
The ornamentation pattern and size of pollen grains jointly provided evidence that it is appropriate for use in classifying the genus Perilla into five varieties of one species, supporting the view that Perilla and the other four related genera can be classified into one subtribe (Perillinae).


Pollen morphological studies in tribe Ocimeae (Nepetoideae: Labiatae): I. Ocimum L
A number of examples are cited in which the pollen morphology supports recent or proposed taxonomic changes, for example the transfer of Erythrochlamys cufodontii Lanza and E. nummularia Hedge to Ocimum, and some notable parallels with taxonomic opinion are shown.
Pollen morphology and taxonomy in North American Labiatae
Pollen morphology is described and illustrated based on SEM studies of 118 species of Labiatae (Lamiaceae) native to North America and the value of pollen as a taxonomic character in this family is discussed.
Reproductive morphology ofMegaleranthis saniculifolia Ohwi (Ranunculaceae) and its systematic implications
It is suggested that M. saniculifolia is closely related to Trollius, and should be included within that genus, i.e., asT.
Pollen morphology of the genera Polygonum s. str. and Polygonella (Polygoneae: Polygonaceae)
The pollen of 30 taxa in two genera, viz Polygonum s.
Both pollen and nutlet morphology suggest that Mosla and Perilla are the most closely related and highly specialized among these genera.
A Taxonomic Revision of Collinsonia (Lamiaceae) Based on Phenetic Analyses of Morphological Variation
Results from field and herbarium observations and from the phenetic analyses indicate that specimens of C. serotina with four stamens represent a distinct species of Collinsonia, which is now recognized as C. canadensis.
The origin of three- and sixcolpate pollen grains in the lamiaceae
6-colpate pollen grains of the genus Prostanthera are reported to be two-celled, which means that similar forms of 6-colPate pollen in systematic groups of Lamiaceae with two- and three-CElled gametophytes originate independently.
Glossary of pollen and spore terminology
Biosystematics of the tribe satureineae(labiatae) in Canada I.
Chromosome numbers of 10 Canadian species have been determined and two counts are recorded for the first time and Pycnanthemum virginianum is found to be apomictic in Canada.
Palynological study of Lavandula (sect. Pterostoechas, Labiatae): Canario-maderiense endemics
Seven endemic taxa of Lavandula L. (sect. Pterostoechas) were studied palynologically by light and scanning electron microscopy and revealed the taxonomic significance of palynological characters.
