As micromorphological knowledge was not available for Coix aquatica Roxb., the foliar epidermal studies were carried out for Coix lacryma-jobi L. and Coix aquatica Roxb. with the aim of determining the patterns of variation in their epidermal characteristics and assessing their value in species identification. Comparative foliar analysis was carried out by using light microscopy, after following routine scraping method. The characters of diagnostic importance in the identification of C. aquatica are the sparsely distributed prickle hairs with long pointed apex in the abaxial epidermis and dumbbell shaped silica cells in both the epidermises. The diagnostic characters for C. lacryma-jobi are the cross shaped silica cells and dumbbell shaped on the abaxial and adaxial epidermis respectively. The observed differences in certain micromorphological characters helps in identification of presently studied two species of Coix.

Epidermal micromorphology of the genus Festuca L. subgenus Festuca (Poaceae)2013 •
Acta Biologica Szegediensis
Epidermal micromorphology of floret parts in Aeluropus (Poaceae)Aeluropus from Poaceae comprises 5 species in the world and 3 species in Iran. This halophytic perennial is distributed in salty and dry soils of Asia, Europe, and Africa. In addition to being used as fodder, it can stabilize the soil by its rhizome or stolon. These features make Aeluropus a valuable plant. In this study, lemma and palea of 10 populations of Aeluropus were studied micromorphologically by scanning electron microscope (SEM) to determine diagnostic features among species studied. Eight characters as micro-prickle, macro-hair, long cell outline, cork and silica cells, papilla, salt gland, and epicuticular wax were studied. The occurrence of salt glands and silica cells in populations/taxa studied showed the ability of Aeluropus to tolerate harsh habitats. Our result showed the taxonomic value of floret micromorphological features to separate Aeluropus species.

Epidermal structure in the ligules of four species of the genus Poa L. (Poaceae1984 •
The structure of the abaxial epidermis of the ligules of mid- and upper-culm leaves of the grasses Poa annua, P. nemoralis, P. pratensis and P. trivialis as seen by light microscopy is described. Amongst the structural elements found were long cells, short cells and unicellular prickle hairs over the surface, with unicellular hairs and papillate cells on the free edges of the ligules. Ligules of upper-culm leaves of some plants of P. trivialis L. contained vascular tissue with associated green (chlorenchyma) regions and stomata-like structures. The value of ligule characters in grass identification and classification is briefly discussed.
This investigation deals with the comparative studies on leaf epidermal micromorphology, vegetative (stem and petiole) anatomy and xylem elements of four members of the family Portulacaceae. The species selected for the study are Portulaca grandiflora Hook., Portulaca oleracea L., Portulaca quadrifida L. and Talinum fruticosum (L.) Juss. which have medicinal importance. In each case, the epidermal cells are irregular in shape and cell wall outline is wavy. Size of epidermal cells ranges from 37.64 µm × 71.25 µm to 48.91 µm × 81.91 µm. Stomata are of paracytic type in all four taxa. Stomatal size varies from 23.52 µm × 16.51 µm to 39.2 µm × 23.36 µm. Stomatal index varies from 12.35 to 19.7. Palisade ratio ranges from 5.75 to 7.84. Stem anatomy of the investigated taxa does not show any variation in the basic pattern of tissue arrangement. Petiole anatomy of the investigated species shows variation in number and arrangement of the vascular bundles. Number of vascular bundle ranges from 4 to 14. Vascular bundles show the circular arrangement in all three species of Portulaca. But in Talinum fruticosum, it is horseshoe shaped. Vessel elements have simple and transverse or obliquely placed perforation plate. Tracheids are with spiral side wall thickening and their width ranges from 15.68µm to 26.41µm. Fibres are long with thick wall and gradually tapering tips. Besides the morphological characters, this study may provide some diagnostic foliar micromorphological and anatomical features that can be used in proper identification of these taxa.

Abnormalities in the female spikelets of Coix lacryma-jobi L. (Poaceae) India2022 •
Genus Coix L. belongs to family Poaceae Barnhart is native to tropical regions of southern Asia to Australia and represented by six taxa (3 species + 3 infraspecific taxa) worldwide. In India it is represented by two species and three varieties. In which Coix lacryma-jobi L. is most diverse taxon all over the world. Fruits of Coix is one of the important characters for the species. In the present communication some abnormalities of female spikelets (utricle) of C. lacryma-jobi in context with number of female spikelets and appearance of leaf blade with different length on utricle are reported for the first time. The abnormalities are showed affinities with related taxa.
The new species Desmostachya pingalaiae Raole & R. J. Desai has been described recently, even though micro-morphological studies were not carried out yet. As micro-morphological knowledge is not available at the moment for D. pingalaiae, comparative analysis in genus Desmostachya L. was carried out on both leaf epidermises, with the aim of determining the patterns of variation in their epidermal characteristics and assessing their value in species identification. Comparative foliar analysis was carried out by using light microscopy, following routine scraping method. The significant diagnostic character for the identification of D. bipinnata is the presence of frequently distributed macrohairs on abaxial epidermis, while for D. pingalaiae is the existence of papillae, flanking the long cells. Silica bodies and papillae, along with routine micro-morphological features, are reported for the first time for D. pingalaiae. Even more, micromorphological characters are also helpful for the...
