The genus Prunus (family: Rosaceae) consists of over 400 plant species and exhibits vast biodiversity worldwide. Given the wide distribution of this genus, its taxonomic classification is important. Anatomical characteristics are conserved and stable and can therefore be used as an important tool for the taxonomic characterization of plants. Therefore, this study aimed to assess and document the anatomical characteristics of the leaf, stem, and seed of P. africana using micrographs and photographs for possible use in the identification, quality control, and phylogenetic analysis of the species. The anatomical sections of a young stem revealed a cortex consisting of isodiametric parenchyma cells, druse crystals, primary vascular bundles, and pith. The mature stem bark majorly consisted of the rhytidome, with the periderm densely arranged in multiple layers; a cluster of stone cells; and sclerenchyma. The leaf sections were hypostomatic, with stomata sizes ranging from 18.90-(22.34)-26.90 × 15.41-(18.40)-21.22 ㎛. The leaf sections showed the presence of characteristic druse crystals, vascular bundles, and mesophyll layers. The pericarp contained the epicarp, mesocarp, and endocarp, with their thickness being approximately 350-400, 300-350, and 30-50 ㎛, respectively. In addition, it contained a seed testa with a thickness of approximately 50-60 ㎛. The morphological and anatomical characteristics observed in P. africana leaves, stems, and seeds in this study could serve as useful data for the taxonomic identification of this species.

Anatomical characters of the Bupleurum latissimum Nakai, an endemic species of Korea, were investigated to confirm its phylogenetic relationships. Compare to other species with anatomical characters, B. latissimum is very similar with B, euphorbioides and B, longeradiatum in point of lacking of pith in the stem, shape of involucres, number of vascular bundles in radical leaf and cauline leaf, and lacking stomata in adaxial leaf surface. The other hand, protruded pollen aperture character appears in B. latissimum and B. euphorbioides. On the based of anatomical characters, therefore, B. latissimum has closest relationships with B. euphorbioides and B. longeradiatum. It also needs molecular study including Asian species in order to confirm phylogenetic position and speciation process apparently.
