    Application of Numerical Taxonomy to Lip Morphology in the Genus Polystachya Hook (Orchidaceae) in Nigeria
    (2009) Folorunso, Abayomi Ezekiel; Jayeola, Adeniyi Akanni
    SCLA, a numerical taxonomic method was applied to lip morphology in the genus Polystachya Hook (Orchidaceae) in Nigeria. The basic data matrix was prepared by coding for the presence or absence of the attributes of characters involved. The data were standardized so that the values of a particular character were transformed into values ranging from zero to one. The SCLA showed that the reproductive characters are much better than the vegetative characters earlier used in distribution of Polystachya species into their sections. In the case of reproductive characters, more clusters were reported; this may be an indication of more sections in Polystachya than those earlier reported.

    Comparative Foliar Epidermal Studies in Andropogon Gayanus (Kunth) and Andropogon tectorum (Schum & Thonns) in Nigeria
    (2009) Folorunso, Abayomi Ezekiel; Olaniyan, Ojuolape Funmilola
    The foliar epidermal studies were carried out on Andropogon gayanus and Andropogon tectorum with the aim of determining the patterns of variation in their epidermal characteristics and assessing their value in species identification and classification. Adaptive and endemic characters that may be useful in the identification of the savanna species (A. gayanus) are long cells longer in length and width; straight anticlinal wall. Typical characters of the genus are important in the identification and classification of the genus; these are cell wall largely thick and straight, stomata amphistomatic, papillae largely numerous and uniform in size.
