Notes on the morphology, ecology and distribution of Quisqualis parviflora (Combretaceae)
Abstract
Background: Quisqualis parviflora Gerrard ex. Sond. is endemic to the KwaZulu-Natal and Eastern Cape provinces, South Africa. The species’ distribution has previously been thought to extend to Mpumalanga and the KwaZulu-Natal midlands. Most published distributions include Maputaland in north-eastern KwaZulu-Natal, and it has been suggested that the species may occur in Mozambique. Sterile material of several Combretum Loefl. lianas may be confused with Q. parviflora . Although the species may be locally common, it has never been collected in fruit. Published fruit descriptions are based on erroneously identified material. Objectives: The aim of this study was to supply a revised distribution range, to describe the fruit of Q. parviflora and to present notes on the phenology and ecology of the species. Method: Herbarium specimens of Q. parviflora , and similar taxa, were examined in various herbaria. Fieldwork was undertaken, and other active field botanists were consulted. Results: Quisqualis parviflora is almost entirely restricted to scarp forest between Port St. Johns in the Eastern Cape and Eshowe in KwaZulu-Natal. Although the species may be locally common, it has only been collected from a few localities. The current dispersal ability of the species may be extremely limited, which could have long-term conservation implications. Samaras are described, and notes are provided on the phenology and ecology of the species. Conclusion: Although not currently threatened, the long-term prospects of Q. parviflora may be less secure. Proposed forest management interventions like liana thinning should not be undertaken without more information.
