Glandular trichomes micromorphology of aerial parts of Sideritis romana L. and Sideritis montana L.
Sideritis romana L. and Sideritis montana L. (Lamiaceae) are annual herbs covered in hairs inhabiting arid meadows and grazings of Europe and the Mediterranean area. In this study, micromorphological observations were performed using light microscopy on the rehydrated dry aerial parts (stems, leaves, calyces and corollas) of three different individual plants from each species collected from wild populations in Croatia, in order to compare these two plant species based on the type and size of occurring glandular trichomes. The gland sizes were assessed based on the measurement of stalk length and/or head width of ten glands of each of the three established gland types, sessile glandular trichomes, unicellular-stalked glandular trichomes and multicellular-stalked glandular trichomes, in triplicate. All three types of glandular trichomes were found on stems, leaves and calyces of S. romana (Sr) and on calyces of S. montana (Sm), while stems and leaves of Sm had only sessile and unicellular-stalked glands (Fig. 1). On corollas of both species, only unicellular-stalked glands were found. Head diameter of sessile glandular trichomes ranged from 20.5 to 36.3 μm in Sr and from 19.5 to 38.8 in Sm. Stalk length of unicellular-stalked glandular trichomes ranged from 6.7 to 70.2 μm in Sr and from 6.4 to 159.4 μm in Sm, while their head diameter ranged from 13.9 to 52.6 μm in Sr and from 20.1 to 48.8 μm in Sm. Stalk of multicellular-stalked glandular trichomes ranged from 65.1 to 562.2 μm in Sr and from 95.3 to 190.6 μm in Sm, while the head diameter ranged from 24.6 to 38.0 μm in Sr and from 25.4 to 48.1 μm in Sm. Glandular classification reported previously for these two species [1, 2] could not have been made here due to the lack of information on glandular structure obtained only by light microscopy. Scanning and transmission electron microscopy imaging would be needed for the more precise systematization of observed glands, which will be the focus of our future studies.
