Abstract

Some morphological and anatomical features of Crinum jagus L. were investigated and described. The student t-tests conducted indicated highly significant differences (P = 0.05) in the mean epidermal cell density, mean stomatal density, mean stomatal length and mean guard cell area between the adaxial and abaxial leaf surfaces. However, the investigation ‘between plants’ variations did not indicate any significant differences (P = 0.05) in all those morphological and anatomical features studied. Moreover, ethnobotanical study of the plant revealed its potency in the treatment of asthma and related coughs. A description of the preparation and application of the asthma concoction is, therefore, presented. The paper discusses the taxonomic and ecological implications of the observations, and recommends an investigation into the phytochemical compounds of C. jagus for possible utilisation in the chemical and drug industries.

Key words: Crinum jagus, anatomy, ethnobotany, herbal medicine, taxonomic description.
