WAHUA, C | PEPPLE, I I
This study examined the macro- and micro-morphological, Anatomical, Cytological and Phytochemical Properties of Tridax procumbens L. in the family Asteraceae. Observations of plant parts aided by measurements were done and these were sectioned following Wahua’s method; root tips squashed with FLP Orcein and qualitative phytochemical analyses were carried out. The slides were viewed using the light compound microscope and photomicrographs were taken after careful examination from good preparations. Macromorphological studies showed the plant grows up to 40cm or more in height. Foliar features revealed opposite, pinnate, oblong to ovate with coarsely serrated margin and acute apex, 4±1.5cm long and 2±1cm wide with petiole up to 1.5±0.5cm in length. The floral structure show cased diameter of each flower head as 1.0±0.4cm while the peduncle is elongated and up to 10±5cm in length; the petal is 0.7±0.2cm in length alongside tubular sepals up to 0.9±0.3cm in length. The stamen is 0.9±0.2cm in length while the carpel is 1.0±0.1cm. Presence of anomocytic stomata which is amphistomatic. Anatomical sections on the mid-ribs, petiole, internodes, nodes and roots revealed peculiar internal features. Mitotic chromosome is 2n=36. Phytochemical studies revealed the presence of saponins, alkaloids, flavonoids, tannins, steroids, cardiac glycosides, phenols. The information generated from this study would further aid in the delimitation of the species.
