The sizes of plant genera vary widely from those containing a single species to genera containing thousands of species, and this disparity became clear early in the history of plant classification. The largest genus in Carl Linnaeus' seminal Species Plantarum was Euphorbia, with 56 species; Linnaeus believed that no genus should contain more ...
The conifer division of plants includes the tallest organism, and the largest single-stemmed plants by wood volume, wood mass, and main stem circumference.The largest by wood volume and mass is the giant sequoia (Sequoiadendron giganteum), native to Sierra Nevada and California; it grows to an average height of 70–85 m (230–279 ft) and 5–7 m (16–23 ft) in diameter.

With around 780 genera and around 12,000 species, [4] the Poaceae is the fifth-largest plant family, following the Asteraceae, Orchidaceae, Fabaceae and Rubiaceae. [ 5 ] The Poaceae are the most economically important plant family, providing staple foods from domesticated cereal crops such as maize , wheat , rice , oats , barley , and millet ...
The family is widely distributed, and is the third-largest land plant family in number of species, behind only the Orchidaceae and Asteraceae, with about 765 genera and nearly 20,000 known species. [7] [8] [9] [10]
Cyatheaceae are the largest family of tree ferns, including about 640 species. [1] Cyatheaceae and Dicksoniaceae , together with Metaxyaceae and Cibotiaceae , do not form a strongly supported monophyletic group and could be paraphyletic, but several individual subgroups are well supported as being monophyletic.
