“…Studies on pollen morphology of the Mimosoideae include those by Rosanoff (1865), Dhyansagar (1955), El Ghazali et al (1997, Tantawy et al (2005), and Elazab (2005). Similarly, pollen morphology of the Caesalpinioideae was studied in detail by El Ghazali et al (1997), Elazab (1998) and Tahavi et al (2004), as well as of individual genera by Larsen (1974) and Pu et al (2003) on Bauhinia, by Fernandez-Pacella (2014) and Doty et al (2020) on Senna, by Fitri & Des (2018) on Caesalpinia, by Wani et al (2015) on Delonix, and by Maw et al (2020) on Parkinsonia. Seed morphology and structure in the Leguminosae as revealed by light and scanning electron microscopy has been the subject of numerous studies by Hussein et al (2002a, b), Al-Gohary & Mohamed (2007), Moawed (2009), Rashid et al (2018Rashid et al ( , 2021, Khan et al (2020), andWaheed et al (2021).…”

The Taxonomic Significance of Pollen and Seed Morphology in The Mimosoideae and Caesalpinoideae (Leguminosae)

P OLLEN and seed morphology of 19 species representing 12 genera of the Mimosoideae and Caesalpinioideae was studies using light and electron microscopy. Observed variations were recorded comparatively in a data matrix and analyzed numerically by the PRIMER Ver.6 program package for cluster analysis. The ensuing dendrogram indicates the division of the species into two main groups. One group includes all members of the Mimosoideae together with all three species of Senna from the Caesalpinioideae. The remaining eight species of the latter subfamily constitute the second group. Apart from the deviation of Senna from the Caesalpinioideae, the distinction between the two subfamilies seems corroborated by differences in pollen and seed morphology. Senna is distinct from Cassia and deserves generic rank. The generic concept in the two subfamilies is taxonomically sound since the group of species representing one genus are attached together before joining those of other genera. Individual genera (such as Calliandra) can be singled out by their pollen aggregations.

“…Pollen grains are used for solving various taxonomic problems, observing climatic influence on plants, and updating conservation efforts (Quamar & Chauhan, 2013; Sivaguru, Mander, Fried, & Punyasena, 2012). Although most of the palynological work on the subfamily Ceasalpiniaceae taxa have been documented for its taxonomic significance in the different geographical region of the world since long, for example, the pollen morphology of Bauhinia (Larsen, 1974; Pu, Dianxiang, & Jingping, 2003), air‐born pollen of Ceasalpiniaceae (Tahavi, Bhutta, Hussain, & Azim, 2004), Senna (Doty, Rashid, & Shethi, 2020; Fernandez‐Pacella, 2014; Shaheen et al, 2019), Caesalpinia (Fitri & Des, 2018), Delonix (Banks, 1997; Wani, Basim, & Abdul, 2015), Parkinsonia (Larson & Lewis Jr, 1961; Maw, Than, & Yee, 2020). However, no such study was yet documented in Pakistan by using both light microscopy (LM) and scanning electron microscopy (SEM).…”

Pollen micromorphology is not only used to check the functional and structural evolution in plants but also to solve the taxonomic problem related to the classification of plants. Therefore, keeping in view the significance of pollen traits, selected taxa of the subfamily Caesalpiniaceae was collected from different geographical regions of Pakistan. The species were then analyzed under both light microscopy and scanning electron microscopy techniques to investigate the importance of micromorphological characters of pollen in the identification and classification of species. Great variation was recorded in equatorial shape, surface ornamentation, tectum, polar diameter, equatorial diameter, and exine thickness. However, little variation was observed in pollen type, polar shape, and fertility of pollen. The equatorial shape of five types was observed: prolate, prolate‐spheroidal, spheroidal‐subprolate, subspheroidal‐prolate, and subspheroidal. Four types of surface ornamentation, psilate, granulate, clavate, and perforate, were recorded. Tectum of five types, intactate, reticulate regulate, medium reticulate, tactate, and striate, was observed. Sexine was thicker than nexine in all studied species. The largest polar diameter was observed in Caesalpinia pulcherrima 64.1 μm while the smallest in Parkinsonia aculeata 26.1 μm. The largest equatorial diameter was found in C. pulcherrima of 70.25 μm whereas the smallest in P. aculeata 27.57 μm. All the pollens analyzed were tricolporate. All studied species have a fertility ratio of more than 90%. A taxonomic key was developed to show the variation in pollen features and delimit species for the correct identification. In conclusion, the pollen traits were found useful to define species boundaries at various taxonomic ranks and will strengthen the taxonomy of this subfamily. Besides, this study also explored the palynological traits and their implication in the taxonomy of the subfamily Caesalpiniaceae.

“…We believe that microscopic studies can provide clarity in this aspect. In this regard, we refer to recent microscopic studies on some species of g. Cassia in general (Sahai, 2001;Ogundipe et al, 2009) and S. occidentalis in particular (Nassar et al, 2013; Begum et al, 2014;Doty et al, 2020). This species is known in English as Coffee senna, Coffeeweed, Piss-a-bed, Mogdad coffee, Negro-coffee, Senna coffee, Stephanie coffee, Sinkingweed or Styptic weed, but the most used English common name is Coffee senna (Allsopp, 1996).…”

The current research deals with the morpho-anatomical characteristics of Cassia occidentalis (L.) (Coffee senna plant), grown in the steppe climate conditions of the Republic of Moldova. This study was performed according to investigated organ in vegetative periods of 2019-2021 years. Morphological and anatomical indices of organs with diagnostic role in identifying species and those with adaptive potential to the action of unfavorable growth factors, have been elucidated. These indices were evaluated in the light of data already reported by other researchers. This morpho-anatomical research has revealed new aspects to support some anatomical features already outlined, but less confirmed in the studies of the last decades and will serve as landmarks for a real clarity of the integral microstructural picture of the C. occidentalis species.
