The heterogeneous ecosystem of the marshland supports about 337 species of floras and faunas. This would ultimately result in the complete devastation of the native floras and faunas. Plants are grouped into floras based on region (floristic regions), period, special environment, or climate. It has one of the most diverse herbaceous plant floras of ecoregions in North America. There are different alpines and evergreen floras. Ethiopia has different climate and geological zones that provide different types floras. Lauroid floras have included forests of Podocarpaceae and southern beech. Annuals are also rare in other alpine floras, including arctic. Herbals were replaced by floras&colon; books that described the native plants of local regions. Grasses are one of the most abundant floras on all continents, except Antarctica. Modern floras separate these groups as the genus "Micranthes". Similar floras are known from the Florissant of Colorado and Oregon. It was misidentified as great hairy willowherb in contemporary floras. It is one of the few completed Floras in Africa. Moreover, many of the floras in Ethiopia can be used flavoring or spice.
