In classification and identification of plant species, palyno morphological character has remain helpful for plant taxonomist. The aim to investigation this study was to identify the characteristic features of Asteraceae and Poaceae family member collected from lower Himalayas of Pakistan. Light microscope and Scanning electron microscope were used for feature study of allergenic pollen. Our study includes 10 species of Asteraceae and Poaceae family. The most dominant shape of pollen was Oblate-spheroidal, Prolate-Spheroidal, Prolate and Suboblate shape of pollen.Quantitative character of pollen includes maximum pollen diameter found in Dichanthium annulatum (46.0 μm) and minimum polar axis pollen diameter found in Parthenium hysterophorous (16.0 μm). Similarly highest value of P/E ratio was noted in Cenchrus echinatus (1.05) and smallest value of P/E ratio was observed in Erigeron bonariensis (0.88). Poaceae family member were monoporate. Character feature of exine sculpturing include Microechinate, granulate, echinate, conical base, lacunae Nanogammate, Aerolate-Scabratre, Verrucate, like variation found in exine of both family member. Highest value of pollen fertility was observed in P. hysterophorous 93%, Similarly maximum value of pollen sterility was noted in E. bonariensis and Brachiaria reptans 24%. This investigation provides the characteristic feature of allergenic pollen species and help to arrange them in define class.

“…Morphologically and palynologically, Euphorbia has been well studied worldwide (Alam et al, 2021; Alyas et al, 2020, 2021; Bahadur et al, 2022; Chaudhary & El‐Ghazaly, 1994; El‐Ghazaly, 1989; El‐Ghazaly & Chaudhary, 1993; Furness, 2011; Lee & Park, 2006; Nobarinezhad et al, 2018; Noh & Park, 2008; Oh et al, 2002; Park, 1997; Perez de Paz & Roca‐Salinas, 1977; Perveen & Qaiser, 2005; Punt, 1962; Shahzad et al, 2022; Weber El Ghobari, 1985; Xia et al, 2008); however, these studies are still insufficient considering the diversity and wide distribution of the genus.…”

Euphorbia L., one of the largest genera of angiosperms, is represented by the subgenera Esula Pers. and Chamaesyce Raf. in Turkey. Subg. Esula is confined mainly to Eurasia, especially in the Mediterranean region, and has not yet been studied in detail palynologically. In the present study, the pollen morphology of 14 taxa belonging to the sections Helioscopia Dumort., Myrsiniteae (Boiss.) Lojac., Pithyusa (Raf.) Lázaro, Patellares (Prokh.) Frajman, Exiguae (Geltman) Riina & Molero, Paralias Dumort., and Esula (Pers) Dumort. of Euphorbia L. subg. Esula Pers. from European Turkey was examined using light and scanning electron microscopy. The pollen grains were found to be trizonocolporate, isopolar, radially symmetrical, medium in size, and oblate spheroidal and suboblate in shape. Ectoapertures were elongated colpi with distinct margins, widened at the equatorial region, and tapered at the ends; margo was present in all samples as a smooth exine surrounding the colpi. The endoapertures were lolongate pori with distinct costae. The exine was tectate‐perforate. The ornamentation was perforate, microreticulate‐perforate, microreticulate‐perforate with rugulose, or microreticulate‐perforate with a heterobrochate pattern. The sexine was generally thicker than the nexine, with some exceptions where the sexine was almost equal to the nexine. Pollen size, pollen shape, and exine ornamentation have taxonomic importance in distinguishing species; however, these features do not provide strong support for grouping or delimitating the taxa at the sectional level.Research Highlights Pollen size, pollen shape, and exine ornamentation are taxonomically important for distinguishing Euphorbia species. The exine ornamentation was observed to be perforate, microreticulate‐perforate, microreticulate‐perforate with a rugulose pattern, and microreticulate‐perforate with a heterobrochate pattern.
