A search for phylogenetically informative pollen characters in the subtribe Salviinae (Mentheae: Lamiaceae) Naturalis
Moon, H.-K.; Vinckier, S.; Walker, J.; Smets, E.F.; Huysmans, S..
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 abrotanoides appears to be distylous and shows a significant pollen dimorphism between pin and thrum flowers. The sexine ornamentation of the genera Lepechinia and Chaunostoma is perforate, while the ornamentation of other genera is bireticulate. Perovskia expresses a unique...

Palynological evolutionary trends within the tribe Mentheae with special emphasis on subtribe Menthinae (Nepetoideae: Lamiaceae) Naturalis
Moon, H.-K.; Vinckier, S.; Smets, E.F.; Huysmans, S..
The pollen morphology of subtribe Menthinae sensu Harley et al. [In: The families and genera of vascular plants VII. Flowering plants.dicotyledons: Lamiales (except Acanthaceae including Avicenniaceae). Springer, Berlin, pp 167-275, 2004] and two genera of uncertain subtribal affinities (Heterolamium and Melissa) are documented in order to complete our palynological overview of the tribe Mentheae. Menthinae pollen is small to medium in size (13-43 mu m), oblate to prolate in shape and mostly hexacolpate (sometimes pentacolpate). Perforate, microreticulate or bireticulate exine ornamentation types were observed. The exine ornamentation of Menthinae is systematically highly informative particularly at generic level. The exine stratification in all taxa...

Comparative pollen morphology and ultrastructure of Mentheae subtribe Nepetinae (Lamiaceae) Naturalis
Moon, H.-K.; Vinckier, S.; Smets, E.F.; Huysmans, S..
This study provides new pollen data of 52 representative species belonging to all 12 genera in the currently classification of the subtribe Nepetinae, and considers the possible presence of orbicules for the first time. Pollenmorphology and ultrastructure were investigated with light, scanning electron and transmission electron microscopy. Nepetinaepollen is small to large (P = 16–65 µm, E = 17–53 µm), oblate to prolate (P/E = 0.7–1.6) in shape and mostly hexacolpate (sometimes octocolpate). The exine stratification in all taxa studied is similar and characterized by unbranched columellae and a continuous, granular endexine. Sexine ornamentation in the Nepetinae is bireticulate, microreticulate or perforate. In perforate and microreticulate pattern a...
