Abstract
This study was carried out in Lalay and Tahtay Maichew districts, Central Zone of Tigray, Ethiopia. The main objectives of the study were to: identify herbaceous flowering plant species found in the study area and to identify community types of the vegetation of the study area. Within 65 sample quadrats, different herbaceous species were collected for taxonomic identification using preferential sampling method and coded for an analysis from 1m x 1m sub-quadrats placed within 20m x 20m quadrat. A total of 132 herbaceous flowering plant species of vascular plants belonging to 99 genera and 34 families were identified. With regards to species number, the most dominant plant family is Poaceae (34 species), followed by Asteraceae (16 species), Fabaceae (14 species). Four community types were also identified at 47.94% to 31.42% similarity levels.
Key words: Floristic composition, taxonomic identification, community types, herbaceous plant species, Lalay and Tahtay Maichew districts.
