Salvia (sage) is a species rich and medicinally important genus. Species-level identification is usually very difficult, particularly in closely related species. Here, we investigated nutlet micromorphological characteristics of 51 taxa belonging to S. subg. Salvia, S. subg. Sclarea and Salvia verticillata clade (S. subg. Heterosphace) by stereo binocular microscopy and scanning electron microscopy to show their taxonomic and phylogenetic value. The present study is the most comprehensive nutlet micromorphological study based on the number of taxa studied in the genus so far. The size of nutlets varies from 1.61 mm (S. verticillata subsp. verticillata) to 8.44 mm (S. albimaculata) in length, 1.02 mm (S. verticillata subsp. verticillata) to 4.20 mm (S. macrochlamys) in width. Nutlet length/width ratio ranges from 1.02 (S. bracteata and S. indica) to 3.06 (S. albimaculata). The basic shape of nutlets is elliptic, widely elliptic, circular, ovate or obovate. Five nutlet sculpturing patterns are present namely colliculate, reticulate, verrucate, rugose and foveate. The variation of surface sculpturing, nutlet shape, size, and exocarp cell shape provide useful diagnostic properties at species and subgenus level. However, nutlet micromorphological characters are of low phylogenetic value in studied Salvia species.


A New Variety of Salvia sericeotomentosa (Lamiaceae) from South Anatolia, Turkey
Celep, Ferhat; Doğan, Musa; Bagherpour, Safi; Kahraman, Ahmet (Missouri Botanical Garden Press, 2009-12-01)
Salvia sericeotomentosa Rechinger f. (Lamiaceae) was First collected by A. Eig and M. Zohary in 1932 and was described in 1952 by K. H. Rechinger, but since that time it has not been collected again from its type locality. Among specimens collected from the Amanos Mountains near Hatay Province, Turkey, in 2006, the taxon was rediscovered oil the basis of two different populations growing at low altitudes. These populations provide the type for the new variety S. sericeotomentosa var. hatayica Celep & Dogan,...
Taxonomic Notes for Salvia aucheri (Lamiaceae) from Southern Anatolia, Turkey
CELEP, FERHAT; Kahraman, Ahmet; Doğan, Musa (Missouri Botanical Garden Press, 2011-04-01)
Salvia aucheri Benth. (Lamiaceae) is a species endemic to Turkey, and the name is lectotypified herein. Two varieties were previously recognized, as S. aucheri var. aucheri and S. aucheri var. canescens Boiss. & Heldr.; the infraspecific taxa are recognized here as subspecies. During revisionary work on Turkish Salvia L., we determined that S. aucheri subsp. canescens (Boiss. & Heldr.) Celep, Kahraman & Dogan differs from subspecies aucheri not only morphologically, but also geographically and phenologicall...
Morphology, anatomy, palynology and nutlet micromorphology of Salvia macrochlamys (Labiatae) in Turkey
Kahraman, Ahmet; Celep, Ferhat; Doğan, Musa (Walter de Gruyter GmbH, 2010-04-01)
Salvia macrochlamys Boiss. & Kotschy, which belongs to sect. Salvia Hedge, is a perennial herb usually growing on rocky limestone slopes in eastern Anatolia. In this study, the anatomical features of the root, the stem, the leaf and the petiole, as well as micromorphological characteristics of the pollen and the nutlet of this species have been investigated using Scanning Electron Microscopy (SEM). Moreover, its emended and expanded description, phenology, current distribution and ecology are also given. An...
Morphology, anatomy, palynology, mericarp and trichome micromorphology of the rediscovered Turkish endemic Salvia quezelii (Lamiaceae) and their taxonomic implications
CELEP, FERHAT; KAHRAMAN, AHMET; Atalay, Zeynep; Doğan, Musa (Springer Science and Business Media LLC, 2014-11-01)
Salvia quezelii is a very little known local endemic species from Turkey. Since 2005, our revisional studies on the genus in Turkey have been shown that previously known two localities of the species including type locality are wrong, and the species has not been collected since 1970. In this study, the type locality of the species is amended and morphological description of the species is amplified and expanded based on large number of specimens. The anatomy, palynology, myxocarpy, mericarp micromorphology...
Salvia ekimiana (Lamiaceae), a new species from Turkey
Celep, Ferhat; Doğan, Musa (2010-03-10)
Salvia ekimiana F. Celep & Dogan sp. nova (Lamiaceae) is described and illustrated from Turkey. It is confined to Yozgat in central Anatolia where it grows in open Pinus sylvestris forest and alpine steppe. The diagnostic morphological characters from closely similar species are discussed.
