“…Leaf trichome study of Hyptis suaveolens [23] revealed the presence of two types of non-glandular trichomes (monocellular and multicellular) and three types of glandular trichomes (peltate, capitate type I and capitate type II). A study conducted on the foliar epidermal characters of ten Senna species and found that Stomatal types of anisocytic, anomocytic, paracytic, tetracytic and haxacytic were found across the species, glandular trichomes were observed in S. hirsuta and S. occidentalis, while non-glandular trichomes are dominant in the remaining species [12].…”

“…As Metcalfe and Chalk [11] reported, leaves are considered as the most varied organ anatomically in angiosperms which provides a variety of anatomical features that can be employed as useful taxonomic characters. Foliar anatomical characters like stomata and trichomes are found instrumental in solving taxonomic problems and its significance have long been recognized by various workers [12].…”

Sida (Family: Malvaceae) belongs to the genus of flowering plants that possess high medicinal value and is used traditionally in almost all parts of the world. There were about 18 species reported from the state of Kerala (India). Among these, some are with taxonomic controversies. Hence micro-morphological characters of leaves such as trichomes can be used as a taxonomic tool for the identification of plants. Their type, presence, absence and distribution are important diagnostic characters in plant identification and plant taxonomy. Plant samples were collected from different localities of Kerala. Foliar epidermal studies were carried out in order to identify the diversity and distribution of trichomes in the selected species of Sida viz., S. acuta, S. alnifolia, S. beddomei, S. cordata, S. cordifolia, S. fryxelli, S. ravii, S. rhombifolia and S. rhomboidea. Six types of trichomes were identified; they were stellate, conical, forked, capitate (short stalked), uniseriate multicellular and peltate. Stellate trichomes were observed in all the species. Conical trichomes were observed in S. beddomei, S cordata and S. fryxelli. Forked trichome was observed in S. acuta, S. cordata, S. cordifolia, S. ravii, S. rhombifolia and S. rhomboidea. Capitate (short stalked) trichomes were observed in S. acuta, S. alnifolia, S. rhombifolia and S. rhomboidea. Uniseriate multicellular trichomes were observed in S. cordifolia, S. fryxelli and S. ravii. Peltate trichomes are observed in all species except S. beddomei, S. cordifolia and S. fryxelli. However, these species could be easily distinguished by their conical trichomes. A bracketed dichotomous key was prepared for the identification of the species considered for the study.

“…The epidermic layer derives from many features such as stomata, trichomes, and other anatomical features of the leaf epidermis, which serve as helpful anatomical tools in plants (Ahmad et al 2010). Taxonomic problems have been widely solved using foliar anatomical characters such as stomata and trichomes (Begum et al 2014). Moreover, foliar epidermal traits are very important for studying systematics and characterization among subfamilies and tribes (Wetzel et al 2017).…”

Abstract. Damaiyani J, Fiqa AP, Rindyastuti R, Lestari DA, Rahadiantoro A, Yulistyarini T. 2022. Comparative anatomical study of leaves for twelve Indonesian woody plant species. Biodiversitas 23: 3744-3754. Foliar epidermal and stomatal features are widely used as plant microscopic traits either from taxonomic or ecological standpoints. The studies on woody plants in the Malesian region which serve as the essential component of tropical ecosystems are still limited. Here we conduct a comparative study on stomatal and epidermal features of twelve important woody plant species from Indonesia using a descriptive method based on the Light Microscope and Scanning Electron Microscope micrographs. The shape, size and stomatal type were revealed in all species studied. Moreover, quantitative features were measured including epidermal cell length and width, solidity (S), aspect ratio (AR), and stomatal index (SI). The study results showed a variation in foliar epidermal and stomatal traits across the species studied. Due to the presence of trichomes and waxes on the abaxial side, not all species can be measured for their stomatal index and epidermal cells. Syzygium polyanthum has the highest stomatal index and cells with complex interlocking shapes, which provide an effective strategy for reducing mechanical stress on epidermal cell walls, making this native species predicted to adapt well when it was planted in habitats with similar environmental conditions.

“…Taxonomic significance of micromorphology and anatomy in delimitation of taxa and establishment of interspecific relationships are well documented (Tschan and Denk, 2012;Meng and Mao, 2013;Begum et al, 2014). Metcalfe and Chalk (1950) studied the anatomy of the family Boraginaceae and found setae (hairs), epidermal surface and cystoliths as diagnostic characters.…”

Micromorphology and anatomy of six Onosma L. species, viz. O. argentata Hub.-Mor., O. neglecta Riedl, O. proballanthera Rech. f., O. rechingeri Riedl, O. sericea Willd. and O. stenoloba Hausskn. ex Riedl from Turky were investigated. Stem anatomy revealed that cuticle layer ranged from 0.6 µm in O. argentata to 1.7 µm in O. proballanthera. Parenchymatous cells of O. neglecta and O. stenoloba possessed more intense starch than the other species studied. In leaf anatomy, the longest palisade parenchyma was found in O. neglecta, while the smallest was noted in O. argentata. Mesophyll structure of O. argentata, O. sericea and O. rechingeri was equifacial (isobilateral), while O. neglecta, O. proballanthera and O. stenoloba presented bifacial (dorsiventral) structure. Rugose nutlet ornamentation was observed in O. argentata, O. neglecta and O. sericea, whereas reticulate type was found in O. proballanthera, O. rechingeri and O. stenoloba. Onosma stenoloba could easily be distinguished from other species by its aesterotrichous indumentum, and in contrary, other species possessed haplotrichous type of indumentum. Micromorphological features of nutlet surface, anatomical features of epidermal surface (trichomes and stomata), and lamina mesophyll structure (dorsiventral and isobilateral) could be useful in solving taxonomic problem of the genus.
