“…Subspheroidal tetraporate pollen was observed in T. jasminoides and were found differ from T. asiaticum having pantoporate type pollen (Sukkaewmanee, ). The pollen of N. oleander was observed as tricolporate with circular outline in polar view, that corroborate with previous findings (Chatterjee, Sarkar, & Rao, ).…”

This was the first comprehensive pollen micromorphological investigation of lactiferous flora (Apocynaceae) of District Rawalpindi, Pakistan. The pollen morphology of 10 species of the family Apocynaceae was observed and documented using light microscopy and scanning electron microscopy. Pollen was found subspheroidal in shape in most of the species, however peroblate shape was noted in Vinca major. Exine sculpturing patterns (psilate, rugulate, scabrate, and microreticulate) were observed. The result indicated that exine ornamentation of Apocynaceae taxa is systematically informative at generic and species levels. Most of the species have tricolporate type pollen but tetraporate pollen was also observed in Trachelospermum jasminoides and tetracolpate in V. major. Minimum equatorial diameter was noted in Carissa edulis (27.13 μm) and maximum in V. major (108.25 μm). Similarly, maximum exine thickness was found in Cascabela thevetia (9.5 μm). In the present findings, the pollen morphological data are compared with available other pollen studies to evaluate the taxonomic value of pollen traits in Apocynaceae taxa by using multiple microscopic techniques. Furthermore, molecular and phylogenetic studies were recommended to strengthen the systematics of Apocynaceae taxa.

“…Apocynaceae family recorded both prolatespheroidal pollen with tetraporate aperture and oblate-spheroidal pollen with tricolporate aperture type. This supports that Apocynaceae has eurypalynous nature and this result agrees with (Chatterjee et al, 2014) According to pollen units, there are two major groups are recognized viz. complex (Polyads) and single (Monads) pollen groups.…”

The pollen morphology of 36 woody species from the New Damietta City, Egypt. Belonging to 20 families of angiosperms, distributed in eighteen dicots and two monocots were investigated. The pollen grains were acetolysed, measured, described and illustrated under light microscopy (LM). Examination of these families revealed great pollen diversity in their qualitative and quantitative characters. The results revealed 58.3% of species with prolate-spheroidal pollen, 16.7% with oblatespheroidal pollen, 16.7% with subprolate pollen, 5.6% with prolate pollen and 2.7% with suboblate pollen. Tricolporate apertures accounted for almost half of apertures types; triporate, monocolpate, tricolpate, tetra-to penta-porate, tetraporate, pantoporate, inaperturate, tetracolporate and spiral aperture representing the remainder. Exine ornamentations ranged from psilate (33.3%), reticulate (27.7%) to micro-reticulate, scabrate, granulate, echinate each represents (2%) and clavate, verrucate, rugulate, striate, psilate-perforate, clavate-reticulate made up (1%) for each type. On the basis of pollen units, number and type of apertures, exine patterns were great diagnostic significance among the examined taxa. Six major pollen types and nine subtypes included in two groups (polyads and monads) were recognized. Description of pollen types, LM micrographs and a key for identification of the investigated taxa are provided.

“…Apocynaceae pollen size, shape, aperture number, and type have proved to be important in recognizing pollen at genus level. Apocynaceae has eurypalynous nature with diverse aperture features ranging from porate to compound colporate, hence useful for identification at genus level (Chatterjee, Sarkar, & Rao, 2014).…”

Palynomorphic studies of 65 common mellitophilous and 16 allergenic flora of Arid and Northern irrigated agroecological zones of Pakistan are carried out in this study by using field emission scanning electron microscope (FESEM).Mellitophilous pollen were extracted from honey samples of selected sites. For collection of local allergenic pollen, previously identified allergy-causing plants were selected. Pollen morphological examination was carried out under FESEM.Diverse range of pollen shapes ranging from monad to polyad and sculpturing ranging from psilate to echinate, scabrate to reticulate, bireticulate, or echinolophate were observed. Brassicaceae, Myrtaceae, Asteraceae, Rosaceae, and Poaceae were observed to be dominant allergenic and mellitophilous families of the selected sites.
