	abstract = {The motivation for this study was the assessment of the combined effects of altitude (200, 950 and 1760 m above sea level) and season (April-October) on leaf structural alterations of Clinopodium vulgare. Raising elevation resulted in a progressive decrease of plant height. As concerns leaf area, low-altitude plants exhibited the highest values earlier in the seasonal gradient than mid- and high-altitude plants. High-altitude plants had thicker leaves than low-altitude plants, only at the beginning of summer. Expanded leaves in August and October plants at 200 m elevation contained dark phenolics, mainly in their mesophyll cells. In mid- and high-altitude plants, leaves were devoid of phenolics during their whole growing period. Leaf stomata were found to increase in density from the lowland to the upland habitats. In addition, on leaves of high-altitude plants, stomata became more numerous from spring to autumn. Glandular hairs were present in low densities, only on the abaxial leaf surface. Non-glandular hairs were denser in the leaves of the 200 m population, which were more hairy on their abaxial side. After August, leaves of 1760 m had smaller chloroplasts with fewer or no starch grains (in October). Chlorophyll a content significantly increased in October leaves at 200 m, but at the same time at 950 and 1760 m it became reduced. F-v/F-m was steadily low in 1760 m leaves, whereas in 950 m leaves (until August) and 200 m leaves (after August) it exhibited the highest values. Principal component analysis revealed that the three-altitudinal populations were distinguished from each other, except for the 200 m plants at the beginning of their development which belonged to the 950 m group. The above results support the suggestion that during summer, the mid-altitude plants grow under more favourable conditions, while after summer, the low-altitude plants appear to operate better. Our results when associated with relevant phytochemical studies could provide a ground for selection of the appropriate plant material for pharmaceutical purposes. (c) 2006 Elsevier B.V.

	abstract = {The genus Killickia is described to accommodate the South African endemic species formerly placed in Micromeria sect. Hesperothymus. Morphological data, as well as results from unpublished phylogenetic studies support its separation from the genera Micromeria and Clinopodium. A new species Killickia lutea Brauchler is described and three new combinations are made. Killickia is characterised as comprising solitary- or few-flowered cymes, a campanulate to subcampanulate (obconical) calyx with similar teeth, a corolla tube with two pubescent ridges and nutlets with scattered minute hairs. A thickened marginal vein in the leaves as typical for Micromeria is absent. As currently understood all species are restricted to the Drakensberg mountains and KwaZulu-Natal Midlands in eastern South Africa. A key to the species, brief notes on anatomy and ecology are provided. (c) 2008 The Linnean Society of London.},

	abstract = {Mentheae are the largest tribe in the family Lamiaceae and economically important, including herbs like mint, sage and thyme. 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. The resulting phylogeny was used to analyse the distribution of selected morphological characteristics such as sexine ornamentation of pollen, nutlet shape with existence of abscission scar and its form, and trichome types. Two monophyletic groups are recognized, which largely correspond to the current subtribal circumscription. Subtribe Salviinae is monophyletic, including the genus Melissa which was a genus of uncertain affinity in Mentheae. Subtribe Menthinae is not monophyletic since Cleonia, Horminum, Hyssopus, Lycopus and Prunella are more closely related with subtribe Nepetinae. Although we could not detect any morphological synapomorphies for each clade, morphological variation seems to be correlated with the molecular phylogeny. A circular abscission scar without distinct lateral areole occurred mainly in Salviinae, while the majority of the species of Mentheae and Nepetinae had a clear areole at the abscission scar. In addition, a reticulate sexine ornamentation is rather common in the Menthinae clade.},
