TY - ABST T1 - Distribution and taxonomic implications of some phenolics in the family Lamiaceae determined by ESR spectroscopy Y1 - 2000 A1 - JA Pedersen SP - 229–253 KW - Chemotaxonomy KW - Constituents KW - Dihydroxy-Phenylethanoid Glycosides KW - Esr KW - Lamiaceae KW - Phenolics KW - Phenylpropanoid Glycosides KW - Plants KW - Pollen Morphology KW - Rosmarinic And Chlorogenic Acid KW - Verbenaceae AB - The dihydric phenolics from the leaves of 365 specimens representing 355 species and varieties of 110 genera of Lamiaceae (Labiatae) have been examined as semiquinones by ESR spectroscopy. Of these 89 genera comprising 194 species belong to the Lamiaceae, whereas 21 genera comprising 161 species have been transferred from the Verbenaceae in the most recent classification. Two chemical characters give strong support to the subfamily division of the Lamiaceae as recognised by Erdtman (1945). (Svensk Bet. Tidskr. 29, 279-285) and others. Rosmarinic acid was observed in 110 species out of 127 studied and confined to the subfamily Nepetoideae sensu Erdtman. These species produce tricolpate pollen grains. 3,4-Dihydroxyphenylethanoid glycosides were observed in 111 species all confined to Lamioideae sensu Erdtman with hexacolpate pollen grains. The acid and the phenylethanoid glycosides were found to be mutually exclusive, apart from one species, Teucrium scorodonia. A compound tentatively assigned as a beta-hydroxy-(3,4-dihydroxyphenyl) ethanoid glycoside, was observed in 49 species, solely confined to subfamily Lamioideae. Furthermore, rosmarinic acid was observed in Aegiphila mollis and in Hymenopyramis brachiata, both belonging to Lamioideae. No phenylethanoid glycosides were observed from any of 5 Hymenopyramis or from any of 30 species of Vitex. The latter result questions the transfer of the genus to Lamiaceae, but strengthens its isolated position. Chlorogenic acid was observed in 34 species and protochatechuic acid in 16 species. Hydroquinone is scattered in the family (4 species) and thymohydroquinone was observed in 7 species all belong to the Nepetoideae. (C) 2000 Elsevier Science Ltd. All rights reserved.

The pollen is mostly medium or sometimes small in size, with a circular amb, oblate to prolate in shape, hexacolpate with granular membranes; the exine is bi-reticulate, with unbranched columellae and a continuous, lamellated endexine. The results indicate that Lycopus is stenopalynous; thus the value of pollen characters for taxonomic applications is limited. Some phylogenetic relationships with other related taxa within the tribe Mentheae are also briefly discussed.

[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 studied is characterized by unbranched columellae. Orbicules are consistently absent in Menthinae. Our palynological data are interpreted in a phylogenetic context at tribal level in order to assess the systematic value of pollen characters and to evaluate the existing molecular phylogenies for this group. Pollen morphology suggests Heterolamium as a close relative of subtribe Nepetinae and supports the molecular affinity of Melissa to subtribe Salviinae.

Using rbcl-specific primers, the rbcL gene was amplified by polymerase chain reaction (PCR) and 1420 bp were sequenced directly, or after cloning. RbcL sequences were evaluated with character-state (maximum parsimony; PAUP) and distance methods (neighbour-joining; MEGA). In agreement with classical systematics all taxa studied cluster outside the Nepetoideae. The following clades are apparent: I - Westringia/Prostanthera, II - Ajuga/Teucrium and III - Scutellaria, Stachys, Lamium and Marrubium. Lamium album, L. amplexicaule and L. garganicum appear as a sister clade to Marrubium. Both share a common ancestor with a second Lamium clade (including L. purpureum, L. maculatum and L. galeobdolon). The phylogenetic relationships are discussed with regard to the systematic classification of the subfamilies Lamioideae and Nepetoideae (sensu Erdtman).
