“…Fabaceae is eurypalynous family (Luz et al, 2013), with vastly diverse pollen characters (Pavlova & Manova, 2000;Taia, 2004;Lashin 2006;Liao et al, 2022). Among the numerous studies that explain the pollen morphology of Fabaceae species: Erdtman (1952), Barth et al, (1976), Graham et al, (1980), Banks & Lewis, (2009), Luz et al, (2013), Antonio-Domingues et al, (2018), Talebi, et al, (2020), Soares et al, (2022).…”

The current study aims at investigating the morphology of pollen grain for eleven woody species of Fabaceae cultivated in New Damietta, Egypt. The pollen grains were prepared according to Erdtman's acetolysis method, described and photographed using light microscopy (LM). The results showed variations in their qualitative and quantitative features. Differences in pollen shape (subprolate, prolate, prolate-spheroidal, oblate-spheroidal), size (medium to large), pollen arrangement (monads or polyads), amb (circular, irregular, elliptic or triangular), polarity (isopolar, heteropolar), type of apertures (porate, colporate, inaperturate) and exine ornamentation patterns (psilate, verrucate, granulate, reticulate and psilate-perforate) are characterized.Electrophoretic (SDS-PAGE) examination of total pollen protein content of four species (Acacia ehrenbergiana, Cassia glauca, Delonix regia, Leucaena leucocephala) revealed distinct protein bands. The results of this study is of great importance in understanding the pollen types of some allergy producing species.

“…Although both species resemble much with each other but still have many morphological differences. Previous literature showed that the palynomorph studies play an important role to evaluate pollen diversity and taxonomic significance (Liao et al, 2021). Morphological differences between the C. Sativa and C. indica were observed .…”

Marijuana (Cannabis) belongs to family Cannabaceae. This plant is a great natural source of cannabinoids, which have several medical applications such as it is used for the treatment of anxiety and psychosis, disorders of motility and epilepsy. However, this plant is also notorious for its pollen allergic reactions. Mainly two species, that is, C. sativa L. and C.indica Lam. are involved in allergic reactions. In this study, morpho‐palynological studies of both the species were conducted. A number of morphological differences were observed in the both species. C. sativa is tall with narrowed leaves and fibrous stalk plant while C. indica is short, bushier, broad leaves, and having woody stalk plant. Both the species are varied in their pollen characteristics. The polar diameter of C. sativa observed was 7.5 μm and equatorial diameter was 8 μm, and its shape was oblate‐spheroidal. C. indica had 7 μm polar diameter, 7.5 μm equatorial diameter but its shape was similar to C. sativa, that is, oblate‐spheroidal. About 40%‑50% people were affected with both these marijuana species and had symptoms of allergies like dry cough, congestion, itchy eyes, sore throat, nausea, a runny nose, watery eyes, and sneezing. It was concluded that both species' pollen are allergy causing and pollen of both species are different with variations in morphological and allergic symptoms. Research Highlights Marijuana has great therapeutic importance but it is also notorious for its pollen allergic reactions. Two species of Marijuana, that is, Cannabis sativa L. and Cannabis indica Lam mainly responsible for these pollen allergies. The present research work focused the morpho palynological analysis of these two Marijuana species through light and scanning electron microscopy.

Taraxacum germplasm resources in northeastern China are not current and do not accurately reflect the actual distribution of the species. The objective of this study was to investigate the morphological traits of Taraxacum species distributed in northeastern China and identify those that will facilitate their classification in this region. Leaf, flower, and achene characteristics of 18 species were used for morphological classification. Scanning electron microscopy (SEM) was used to examine pollen morphology. Internal transcribed spacer (ITS) sequences were analyzed to determine sequence differences among the species and their utility in delimitation. Taxa were classified into groups based on their morphology. The ITS sequence analysis supported the taxon classification, but the genetic distances among the taxa did not reflect morphological differences. Phylogenetic analysis was used to divide the 18 species into three groups. Group I: T. coreanum (which has white flowers). Group Ⅱ: T. heterolepis, T. sinomongolicum, T. variegatum, T. asiaticum var. lonchophyllum, T. falcilobum, T. brassicaefolium, and T. erythropodium (outer involucre bracts, narrow membranous or nonmembranous). Group Ⅲ: T. formosanum, T. liaotungense, T. mongolicum, T. borealisinense, T. ohwianum, T. platypecidum, T. urbanum, T. antungense, T. asiaticum, and T. junpeianum (outer involucre bracts, broad membranous). The main taxonomic characteristics of Taraxacum floral organs and achene morphology.
