ABSTRACT

Abstract: Geographical distribution and morphological features of the genus Crotalaria were studied. Methods follow conventional practice as reported by previous studies. Thirty six species of the genus Crotalaria were shown to be distributed in Nigeria. The genera were allopathic in nature. The species such as C. bongensis, C. atrorubens , C. cleomifolia , C. anthyllopsis, C. cuspidata, C. bamendul, C. calycina, C. hyssopifolia, C. incana, C. graminicola and C. macrocalyx were prominent in savannah zones while C. acervata, C. cylindrical, C. cephalotes, C. comosa, C. retusa, C.doniana, C. glauca, C. falcata , C. goreensis among others were common in cultivated areas in forest zone of Nigeria. Qualitative leaf morphological features of selected crotalaria species in Nigeria were also revealed. It shows that the leaf margin, leaf surface and leaf base are similar in features except in leaf shape that vary from lanceolate (C. comosa and C. bongensis), oblanceolate (C. retusa, C. goreensis, C. ononoidea and C. lachnosema) to obovate (C. mucronata and C. naragutensis). This implies that most of the genus Crotalaria displays similar characteristic and the features among them shows overlap.
