Epiphytes exist in the Federal Capital Territory communities but there is little or no information on their diversity and taxonomy. However, Federal Capital Territory is a treasure house of ethnic communities and some valuable plant species. One major gap across the Federal Capital Territory, is lack of formal record on the diversity and taxonomic classification of the epiphytes. The objective of this study is to collect and identify epiphytes present in the Federal capital Territory, determine species composition and abundance, and further identify the various plants used as hosts by the epiphytes. The greatness of epiphytes has enabled them to exploit a wide range of habitats including tropical and temperate woodlands, plantations and mangroves. In tropical canopies, epiphytes are remarkably diverse and show asynchronous phonological patterns at the community level. A reconnaissance survey of the study on diversity and taxonomic classification of epiphytes was carried out from November to December, 2021 in Abaji, Abuja Municipal, Bwari, Gwagwalada, Kuje and Kwali area councils of the Federal Capital Territory (FCT), Nigeria. Eighteen study points were randomly selected from the administrative town and two settlements from each of the area council. The study sites were selected considering the dry riparian nature of the region, altitudinal ranges, notable presence of epiphytes diversity and recommendation from respondents. Data was collected by administering semi-structured questionnaires to 90 respondents for a single face-face interview. Epiphytic plants collected from the field were identified. Those that could not be identified were taken to the Biological Sciences Department, University of Abuja, for identification and documentation. The epiphytes were classified into eight (8) taxonomic groups namely; Polypodiophyta, Tracheophyta, Basidiomycota, Magnoliophyta, Ascomycota, Bryophyta, Marchantiophyta and Anthophyta while four (4) evolutionary taxonomic groups were identified. Based on their mode of life, some epiphytes were classified as Typical Epiphytes while others were Semi Epiphytes and Occasional Epiphytes. The study shows that different epiphytic plants occur in the Federal Capital Territory (FCT), Nigeria, and they belong to various taxonomic groups. Epiphytes in the Federal Capital Territory, and their Taxonomic Groups, indicated that Nephrolepis bisserata (Sw.) Schott, Platycerium stemaria (P.Beauv.) Desv., Ficus benghalensis L., Ficus vogelii Miq., Elaeis guinensis Jacq., Ageratum conyzoides (L.) L., Ficus leprieurii (Miquel), Ficus lutea Vahl, Ficus thonningi Blume, Ficus exasperate Vahl., Ficus platyphylla Delile, Polyhandra longiflora L., Digitaria ciliaris (Retz.) Koeler, Lycoperdon spadiceus Pers., Auricularia polytricha (Mont.) Sacc., Viburnum tinus L., Plagiothecium undulatum (Hedw. Schimp., Frullania dilatata (L.) Dumort., and Ficus aurea Nutt. occured in all the area councils of the FCT while Fomitopsis sp P.Karst., Entodon sp MÜll. Hal. and Funaria sp  Hedw. were seen in Abaji, Bwari, Gwagwalada, Kuje and Kwali area councils. Nephrolepis undulata (Afzel. Ex Sw.) J.Sm. occurred in Bwari, Kuje and Municipal area councils. Coprinus lagopus P.Karst., Daldinia concentrica (Bolton) Cesati and de Notaris, Entodontopsis nitens (Mitt.) W.R.Buck and Ireland, Syntrichia laevipila (Brid.) K.F.Schultz. occurred in Bwari, Gwagwalada, Kuje, and Municipal area councils. Having studied the diversity and classification of epiphytes of the Federal Capital Territory, it is recommended that further research analysis be carried on the phytochemical constituents of some of these epiphytes to determine their major classes of compounds.
