Ethnobotanical and Floret studies on Twelve Species of the family Asteraceae in Ile-Ife, Osun state, Nigeria.
Ethnobotanical and floret studies were carried out on 12 species of family Asteraceae in Ile-Ife, Osun state, Nigeria. The aim was to assess the extent of use of medicinal plants by the tribal and local people and to determine the importance of floret number in the taxonomy of the members of family Asteraceae. Data were gathered through interviews and structured questionnaire to show that the tribal and local people utilize different plant species for treatment of diseases. In this study, 12 species with ethnobotanical values were identified as being used by the local people as food, fuels, and medicine. Floret study was done by studying 25 capitula each from 20 plants of each species. Capitula at anthesis were harvested randomly from the species planted in garden and screen house. Each capitulum was dissected by means of a pair of forceps and mounting needle to detach the florets from the receptacle. The detached florets were counted to know the number of florets contained in each capitulum. Data were subjected to One Way Analysis of Variance (ANOVA) with Post hoc test for significant differences among the species at p<0.05. The result of study indicates that the 12 species of the family Asteraceae studied were commonly used as food, fuel and medicine. Similarly, there was significant difference in floret numbers among the species. Mean floret number of the species ranges from 16.60 in Vernonia amygdalina to 91.64 in Crassocephalum crepidioides. Conclusively, this study shows that, ethnobotanical and floret studies also helps in taxonomic studies and characterization of plant species.
