	abstract = {Pericarp structure is investigated in 143 speci- mens belonging to 59 out of ca. 65 genera and 134 out of ca. 2,000 species of Lamiaceae subfamily Nepetoideae tribe Mentheae. Some of the data presented by earlier authors are believed to be incorrect. The variation in pericarp structure has been found to be strongly correlated to the variations in DNA and gross morphological characters. The groups of two-sta- minate genera (Salvia, etc.) and four-staminate genera of Salviinae (Lepechinia and Chaunostoma) can be distin- guished from each other and from other labiates by differences in pericarp structure. The other two subtribes, Menthinae and Nepetinae, differ considerably, but their variations strongly overlap. The differences in pericarp structure also suggest that Menthinae can be divided into three main monophyletic groups based on other data: (1) the main bulk of the tribe, (2) a group of Prunella and Cleonia and perhaps also Horminum, and (3) the characteristic genus Lycopus. Pericarp data dis- agree with a suggestion that the genus Melissa should be included in the subtribe Salviinae. Modifications of the sub- tribal classification of Mentheae are discussed.},

	abstract = {Pericarp structure was investigated in 158 species of the families Lamiaceae and Verbenaceae. Data from 221 out of 262 genera of Lamiaceae s.l. and a few of Verbenaceae s.str. were collected in a table. A cladistic analysis was performed on the basis of pericarp characters only. The abandonment of subfam. Pogostemonoideae as a taxonomic unit is considered. Examples of groups given additional support by similarities in pericarp characters are: (1) the gynobasic-styled labiates (subfamilies Pogostemonoideae, Lamioi deae, Nepetoideae); (2) a Lamioideae-Pogostemonoideae-group; (3) Nepetoideae; (4) a Westringia-Hemigenia-Hemiandra-Microcorys group (in subfam. Chloranthoideae); (5) a Lepechinia-Chaunostoma-group (in Nepetoideae); (6) a Prunella-Cleonia-group (in Nepetoideae).},

	abstract = {Calyces of 306 species representing 181 out of the 236 genera of Lamiaceae have been studied with particular emphasis on the amount of fibres and similar xylem cells. A characteristic calyx tissue called "mesophyll fibres", reported by earlier authors, is found to belong to the xylem. Most species of the subfamilies Lamioideae and Scutellarioideae differ from most other labiates, and particularly from Nepetoideae, in having much larger amounts of fibres and similar xylem cells in the calyx tube. This result supports cladistic hypotheses based on cpDNA showing that Lamioideae and Scutellarioideae are closely related and remotely related to Nepetoideae. The new data also contribute to the knowledge about the phylogeny within Lamioideae. The amount of fibres and similar cells also seems to be positively correlated with calyx size, calyx width, a ballistic dispersal mechanism in Scutellaria, and the aridity of the habitat. Possible adaptive significances of these correlations are discussed.},
