(Amaranthaceae)]]>OkekeN.F. IlodibiaC.V. OkoliB.E. 4201994Background and Objective: Plants from the Amaranthaceae are used in folk medicine for their nutritional qualities and for the treatment of various disorders. To classify plants, taxonomists make use of anatomy, phytochemistry etc as taxonomic lines of evidence to determine their similarities and differences in order to group them into various taxa. An evaluation of comparative anatomical studies was carried out on various parts of Amaranthus spinosus, Celosia argentea and Gomphrena celosioides to ascertain their anatomical characteristics that delimit them as members of the family Amaranthaceae. Materials and Methods: The transverse sections of roots, stem, leaves and petioles were carried out using microtomy while abaxial and adaxial surfaces of mature leaves were studied using epidermal peels technique. Results: Results revealed similar striking features among the species such as possession of anomocytic stomata on both abaxial and adaxial surfaces, collateral vascular bundle and pinkish pigment found in their parts. Differences were seen in number, arrangement and shape of the vascular bundles and number of layers present in various tissues. Conclusion: Study concludes that three species were related and this justified their placement under the same family Amaranthaceaewhile the differences among them suggest the reason for their separation into different genus.]]>Gills, L.S.,1988Pages: 338Pages: 338Illoh, H.C.,1980Amaranthus Linn. and Celosia Linn.]]>1980Sauer, C.O.,1952Agyakwa, C.W. and I.O.
