Morphology, anatomy, palynology and nutlet micromorphology of Salvia macrochlamys (Labiatae) in Turkey

Abstract

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. Anatomical characters such as the number of ray lines in the root, the distance between vascular bundles in the stem, the structure of mesophyll in the leaf and the structure of vascular bundles in the petiole have been found to have taxonomic value. The pollen grains are hexacolpate, radially symmetrical, isopolar and oblate-spheroidal. Their exine sculpturing is bireticulate and perforate. The nutlets are rounded-trigonous in transverse sections, broadly ovate to rotund in shape, light brown, glabrous and slightly rough to protuberances. This species often grows in habitats in which the main soil type is sandy-clayish with low organic content (1.32 ± 1.06%) and slightly alkaline (pH 7.75 ± 0.25). The amount of CaCO3 is 0.94% to 34.91%. The contents of P and K are 8.68 ± 0.96 and 110.12 ± 4.86 ppm, respectively.

Nutlet Micromorphological Study on <i>Salvia</i> L. (Lamiaceae) from NE Iran

“…Ozkan explained S. aethiopis and S. virgata nutlets ornamentation are foveate and reticulate while in present research, it was preferred to name, surface with hexagonal prominences and undulated stripped respectively. Also, Kahraman et al pointed the size, shape and ornamentation of S. ballsiana, S. macrochlamys and S. hedgeana are diagnostic [7,8]. In conclusion, the shape, color and ornamentation of Salvia mericarps varied among the species and those are taxonomical characters help to identify species.…”

“…Although Salvia is the largest genus of Lamiaceae, its mericarp morphology has been poorly reported. There have been a few reports of external micromorphological study on the mericarp of Salvia such as, Nutlet morphology and its taxonomic utility in Salvia from Turkey [6], Morphology, anatomy, palynology and nutlets micromorphology of the rediscovered Turkish endemic Salvia ballsiana and their taxonomic implications [7], Morphology, anatomy, palynology and nutlets micromorphology of Salvia macrochlamys in Turkey [8]. This research tries to present identification key of species based on micromorphology of mericarp.…”

Morphological and Anatomical Studies on Selected Lamiaceae Medicinal Plants in Bani Matar District, Sana'a (Yemen)

“…The anatomical characters of vegetative organs are important for characterization of Lamiaceae taxa (Metcalfe & Chalk, 1950;Abu-Asab & Cantino, 1987;Kahraman et al, 2009Kahraman et al, , 2010. The glandular hairs and their distribution (Werker, 2006), stomatal distribution and other anatomical features provide significant taxonomic information (Dinç & Öztürk., 2008;Celep et al, 2011 andVenkateshappa &Sreenath, 2013).…”

Pollen morphology of Hymenosphace and Aethiopis sections of the genus Salvia (Lamiaceae) in Turkey

“…There are a large number of studies on pollen morphology in Lamiaceae (Erdtman, 1945;Cantino et al, 1992;Harley et al, 1992;Cantino, 1993, 1994;Celenk et al, 2008;Moon et al, 2008aMoon et al, , 2008bMoon et al, , 2008cSalmaki et al, 2008;Hassan et al, 2009;Aytaç et al, 2012), but only a few studies have been conducted on Salvia (Henderson et al, 1968;Jafari and Nikian, 2008;Hassan et al, 2009;İlçim et al, 2009;Kahraman et al, 2009aKahraman et al, , 2009bKahraman et al, , 2010aKahraman et al, , 2010bKahraman et al, , 2010cKahraman et al, , 2011Kahraman and Doğan, 2010;Celep et al, 2011;Özler et al, 2011). Henderson et al (1968) gave brief descriptions of the pollen morphology of 59 Salvia taxa, 20 of which grow in Turkey.…”
