“…Palynological analysis can be used in research on pollination, pollen dispersion, paleoecology, melissopalynology and forensics. Furthermore, it has fundamental importance in the study of ecological and evolutionary characteristics and phylogenetic relationships of different groups of plants (Cancelli et al 2005; Cui et al 2019; Mezzonato-Pires et al 2019; Gonçalves-Esteves et al 2022; Quamar et al 2022; Cartaxo-Pinto et al 2022a, 2022b, 2022c, 2023). The study of pollen grains is a useful tool for elucidating the taxonomy of several botanical families, and circumscribing genera and subgeneric categories (Gonçalves-Esteves et al 2022).…”

Calea comprises 157 species that occur in the Neotropics. The genus is organized into eight subgenera and 18 sections. Calea sect. Meyeria consists of eight species occurring exclusively in south-central Brazil. In this study, pollen grains from these eight species were sampled from herborized flower buds in pre-anthesis. Pollen samples were acetolyzed, measured, and photographed under a light microscope. Unacetolyzed pollen grains were examined under a scanning electron microscope. The results were used to characterize pollen morphology and construct a palynotaxonomic key for Calea sect. Meyeria. The analyzed pollen grains were monads, isopolar, usually medium-sized, oblate spheroidal, tricolporate, with lalongate endoaperture, the sexine echinate and thicker than the nexine, and six spines in the apocolpium region. The eight species have very similar pollen grains, but some characters are informative for this section, namely pollen size, polar area, sexine ornamentation, and endoaperture characteristics. Despite the similarity of the pollen grains, palynological analysis was able to contribute to the delimitation of Calea species, providing new information for species distinction within Calea sect. Meyeria.

“…8 Barteria nigritiana (Passifloraceae) is a popular softwood sparsely distributed in Eastern Nigeria and respectively called Ukwuifia, Oko and Idon zakara by the Igbos, Yorubas and Hausas in Nigeria. 9 The scanty volume of information available on this plant has recently elicited interest in them. The plant is useful in ethnomedicine due to its antimicrobial and antioxidant activities.…”

Each phase relies on one another to enable the wound to completely seal giving no lasting evidence of tissue damage and understanding what each state involves is crucial in developing a comprehensive healing plan. 6 It is a stepwise occurrence requiring a biochemical process leading to the repair and regeneration of injured cells. Currently, numerous drugs are available for healing wounds such as antibiotic ointment, antiseptics, corticosteroids, and antioxidants but with many adverse effects which include; kidney failure, Steven Johnson's syndrome, dermatitis, and GIT symptoms. 7 Additionally, plant or plant parts contain phytoconstituents which confer the plants with a wide range of activities including antimicrobial, antioxidant, and anti-inflammatory activities that are the main ingredients in the management and healing of wounds with little or no adverse effect. 8 Barteria nigritiana (Passifloraceae) is a popular softwood sparsely distributed in Eastern Nigeria and respectively called Ukwuifia, Oko and Idon zakara by the Igbos, Yorubas and Hausas in Nigeria. 9 The scanty volume of information available on this plant has recently elicited interest in them. The plant is useful in ethnomedicine due to its antimicrobial and antioxidant activities. 10 It possesses wounding healing property in folk medicine. 11,12 Traditionally, the crushed leaves are made in paste form and applied to fresh wounds to initiate their healing activity. In some parts of Southeastern Nigeria, the liquid is usually squeezed out from the fresh leaves and applied to fresh wounds for faster healing. These practices have not been validated scientifically. An extensive phytochemical analysis identified the presence of steroids, tannins, alkaloids, oxalate, flavonoids, cyanogenic glycosides, phenol and lipids in abundance with traces of saponins, phlobatanins and terpenoids. 10
