“…Reproductive biology and systematics are interrelated (Anderson et al, 2002). Its importance in the taxonomic description of species has been harnessed by many researchers (Folorunsho & Olorode, 2008;Ratha & Paramathma, 2009;Bolaji et al, 2020). This study revealed that green-stemmed and red-stemmed Basella alba plants were similar in their reproductive characteristics.…”

Basella alba is an important, underutilised vegetable rich in vitamins and consumed in many parts of the world. However, the reproductive biology of this species is insufficiently known; therefore, this study was performed aiming to fill this knowledge gap. Although green-stemmed and red-stemmed Basella alba share a lot of reproductive attributes in common, the obtained results showed differences in their flower bud apex colour, anther colour, spike colour, days to 50% flowering, plant height at flower bud initiation and the mean number of flowers per spike. In both forms, the floral attributes favoured self-pollination. However, the possibility of cross-pollination among them due to the activities of pollinators such as ants, moths, butterflies and bees suggests a mixed mating system. Furthermore, both forms attained sexual maturity at varying periods, thus indicating the existence of a temporal prezygotic barrier between them and limiting the chances of their hybridisation. They could also be responsible for the ability to remain in their distinct forms even when they exist together in the same habitat.

“…The fruit are berries, capsules or a dry fruit, though in some genera the pistils are located in an elongated receptacle that transforms into an aggregated and pulpous fruit. Seeds of a complicated structure, but with the endosperm ruminated or cracked (Brummitt, 1992;Folorunso & Olorode, 2006;Gottsberger, 1999;Mabberley, 1993;Purseglove, 1968). The leaves of the genus Annona are firm and coriaceous, deciduous or persistent, without stipules.…”

An overview of the genus Annona in the Family Annonaceae is provided in this review. The mainly neotropical family of trees and lianas has numerous commercial fruits that are eaten fresh, processed, or used as popular medicines. The family has 109 recognized genera and from 2,300 to 2,500 species. The taxonomy, morphology, and cytology of Annona spp. are discussed. The genus Annona has the most fruits of commercial importance, including the cherimoya (A. cherimola Mill.), soursop (A. muricata L.), sugar apple (A. squamosa L.), ilama (A. diversifolia Saff.), pond apple (A. glabra L.), biriba (A. mucosa Jacq. formerly Rollinia deliciosa Saff.), and hybrids such as the atemoya (A. squamosa × A. cherimola).
