    Chemical Composition of a Tropical Fern Ceratoptelus Cornlita (Parkeriaceae, Pteridophyta) in Nigeria
    (2010) Oloyede, F. A.; Oloyede, F. M.; Saliu, T. L.; Ogunwole, A. A.
    Extracts from some fern species have been found to be useful in fortifying livestock and fish feeds to enhance production especially in peasant communities. The chemical composition of Ceratoptc.ris cornzltn has not been documented insNigeria. This study was thus designed to determine its suitability for use in fortifying fish feed by analysing the nutrient and anti-nutrient contents of its dimorphic fronds separately. One kg of sterile and fertile fronds of C.cornuta were collected, washed using distilled water and oven dried at 40 OC for about 96 hours. The dried samples were milled and analysed for proximate minerals, cyanide and oxalate analyses in triplicates. Results of the nutrient and anti-nutrient analyses show that both the sterile and the fertile fronds of C. cornuta can be used in aquaculture. The crude protein (4.22-5.28 g/100 g), moisture (87-91.00 g/100 g), carbohydrate (3.12-7.40 g/100 g), magnesium (23.55-194.65 mg/100 g), calcium (0.03 mg/100 g), potassium (0.17 mg/100 g), sodium (0.17 mg/100 g), silver (50.0 mg/100 g), cobalt (3.75-4.45 mg/100 g), lead (53.5-172.5 mg/100 g), copper (60.45-61.0 mg/100 g), manganese (15.65 mg/100 g), arsenium (50 mg/100 g), cadmium (3.75-4.50 rng/100 g), iron (430.00-537.45 mg/100 g) and selenium (106.83-195.45 mg(100 g) contents are considerably high. The anti-nutritional oxalate (0.861.38 mg/100 g) and cyanide (0.88-1.16 mg/100 g) are low and fall within the safe and acceptable limits as recommended by the World Health Organisation. Thus, extract from these fronds can be incorporated into livestocks and fish meals.

    Taxonomical Studies of Selected Ornamental Plants
    (2007) Oloyede, F. M.; Illoh, H. C.; Oloyede, F. A.
    The neglect of ornamental horticulture by researchers in Nigeria is now more evident than ever. This might be attributed partly to general lack of interest in ornamental studies and also partly due to plant identification problem. This work is therefore aimed at the collection, identification, description and propagation of eight ornamental plants of Nigeria [Caladium bicolour Wightii, Chrysothemis pulchella (Donn ex Sims) Decne., Coleus blumei Benth, Episcia cupreata (Hook) Hanst, Impatiens balsamina L., Kalanchoe fedtschenkoi Harnet and Perr 'Marginata', Pellaea rotundifolia (G. Forst) Hook and Rhoeo spathacea (discolor) Hance]. The plants were collected in Osun State, Nigeria and identified using standard horticultural literatures and herbarium specimens of the Department of Botany, Obafemi Awolowo University, Ile-Ife, Nigeria. The plants were raised in triplicates at the screen house. Data were collected on growth parameters. Morphological observations showed that the plants were herbaceous and annuals with simple leaf habit. There were variations in the shapes of their apex, base, margin, calyx and petal. The number of their calyx, petal and the leaf arrangement also differ. Reticulate venation was common to them with the exception of C. bicolor and R. spathacea with parallel venation. They possess actinomorphic flowers except I. balsamina with zygomorphic flowers. Almost all the plants studied are propagated by stem cuttings with the exception of I. balsamina, P. rotundifolia and R. spathacea. Their maturity periods range from 25 - 150 days. The need for awareness of the importance of ornamental plants for their values was discussed.
