Abstract
AbstractThe anatomical structure of the fruits of 48 African species of Peucedanum s.l. and related genera Lefebvrea, Physotrichia and Steganotaenia has been studied. The fruits have been described for 23 diagnostic characters. Carpo‐anatomical structure in the species investigated has appeared to be rather variable in spite of being comparatively similar in outer mericarp morphology. The peculiarities in secretory system, structure of marginal winged ribs, as well as thickness and histological structure of pericarp are the most valuable diagnostic features. Eleven carpological groups have been separated; six of them, containing the species distributed exclusively or mainly in southern Africa, are described in the present paper. Only a small group of six species is similar to the type of Eurasian sect. Peucedanum, however these African species differ from typical species of Peucedanum in vegetative morphology and in inflorescence characters. The results obtained show the necessity of taxonomic revision in African species of Peucedanum.
