The pollen morphology and ultrastructure of the subtribe Salviinae were investigated with light, scanning electron, and transmission electron microscopy. In addition, cladistic analyses of the obtained morphological data, supplemented with rbcL data from GenBank, were conducted in order to assess the phylogenetic signal of palynological characters. Salviinae pollen is small to large, oblate to prolate in shape, with a circular to slightly elliptic amb, and mostly hexacolpate. Perovskia… 
Palynological evolutionary trends within the tribe Mentheae with special emphasis on subtribe Menthinae (Nepetoideae: Lamiaceae)
Pollen morphology suggests Heterolamium as a close relative of subtribe Nepetinae and supports the molecular affinity of Melissa to subtribe Salviinae, and proposes a phylogenetic context at tribal level for this group.
Phylogeny of tribe Mentheae (Lamiaceae): the story of molecules and micromorphological characters.
The evolutionary history of this tribe was reconstructed based on ITS and trnL-trnF spacer sequence data of 71 species, representing 47 out of 65 genera, and morphological variation seems to be correlated with the molecular phylogeny.
Pollen morphology of Callicarpa L. (Lamiaceae) from China and its systematic implications
Pollen morphology of 36 species and 9 varieties of Callicarpa L. (Lamiaceae) from China was investigated through scanning electron microscopy and results do not support the traditional infrageneric classification of Calliarpa which is based on stamen characters, but pollen characters provide evidence to support CallicARPa as the sister to the Australian subfamily Prostantheroideae.
Micromorphology and Character Evolution of Nutlets in Tribe Mentheae (Nepetoideae, Lamiaceae)
Abstract Mentheae is an economically important tribe in Lamiaceae with many ornamentals and culinary herbs. Although its monophyly is well supported by molecular data, the subtribal delimitation
Systematic Importance of Pollen Morphology of Some Plants of (Lamiaceae)
Pollen morphology of seven taxa belonging to Lamiaceae and common used as medicinal plants were examined by light (LM) and scanning electron microscopy (SEM) and the presence of holes on colpus membrane ornamentation can be used as a taxonomic tool for sectional division between.
Pollen morphology of Hymenosphace and Aethiopis sections of the genus Salvia (Lamiaceae) in Turkey
Palynological characteristics of 30 Salvia taxa in sections Hymenosphace and Aethiopis from Turkey were investigated by light and scanning electron microscopy and the basic shape of the pollen grains in most taxa is suboblate, oblate-spheroidal, or prolate-sp heroidal to spheoidal.


Salvia (Lamiaceae) is not monophyletic: implications for the systematics, radiation, and ecological specializations of Salvia and tribe Mentheae.
In a preliminary investigation of infrageneric relationships within Salvia, the monophyly of the genus and its relationship to other members of the tribe Mentheae were investigated using the chloroplast DNA regions rbcL and trnL-F.
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.
Staminal evolution in the genus Salvia (Lamiaceae): molecular phylogenetic evidence for multiple origins of the staminal lever.
It is suggested that Salvia is clearly polyphyletic, with five other genera intercalated within it, and staminal evolution has proceeded in different ways in each of the three lineages of Salvia but has resulted in remarkably similarStaminal morphologies.
Palynological variation in balsaminoid ericales. I. Marcgraviaceae.
A detailed palynological survey of the Marcgraviaceae family is presented in order to comment on the intrafamily relationships and possible correlations with pollinators, finding no clear correlations between pollinators and pollen features.
Pollen morphology of the genus Lycopus (Lamiaceae)
The pollen morphology of 15 species of the genus Lycopus (Lamiaceae, Mentheae) was studied and documented in detail and indicates that LycopUS is stenopalynous; thus the value of pollen characters for taxonomic applications is limited.
Heterostyly in the Lamiaceae: The case ofSalvia brandegeei
It is proposed that the evolution of distyly in Salvia brandegeei may have been associated with an ecological shift to a new environment in which protandry failed to prevent increased levels of geitonogamy and Heterostyly was then selected because it increased the proficiency of cross-pollination.
Evidence for a polyphyletic origin of the Labiatae
A preliminary cladistic analysis suggests that the Labiatae are polyphyletic as presently circumscribed, nested within a larger group characterized by suprareticulate pollen and a fruit composed of nutlets.
Orbicules in angiosperms: Morphology, function, distribution, and relation with tapetum types
The distribution of orbicules throughout the angiosperms, based on a literature review from the first report until today, is shown in a list with 314 species from 72 families, together with their tapetum type.
