Megaflora
Megaflora (from Greek μέγας ''megas'' "large" and New Latin ''flora'' "plant life") refers to an exceptionally large plant species. Examples of megaflora include the Sequoioideae of California and a number of extinct plant species from the Mesozoic. Examples ;Africa *''Adansonia digitata'' ;Oceania *''Eucalyptus regnans'' ;Eurasia *''Ficus benghalensis'' ;Central and South America *''Ceroxylon quindiuense'' ;North America *''Sequoia sempervirens'' See also *Megafauna *Megaherb Megaherbs are a group of herbaceous wildflowers growing in the New Zealand subantarctic islands and on the other subantarctic islands.

Sequoioideae
Sequoioideae, popularly known as redwoods, is a subfamily of coniferous trees within the family Cupressaceae. It includes the largest and tallest trees in the world. Description The three redwood subfamily genera are '' Sequoia'' from coastal California and Oregon, ''Sequoiadendron'' from California's Sierra Nevada, and ''Metasequoia'' in China. The redwood species contains the largest and tallest trees in the world. These trees can live for thousands of years. Threats include logging, fire suppression, climate change, illegal marijuana cultivation, and burl poaching. Only two of the genera, ''Sequoia'' and ''Sequoiadendron'', are known for massive trees. Trees of ''Metasequoia'', from the single living species ''Metasequoia glyptostroboides'', are much smaller. Taxonomy and evolution Multiple studies of both morphological and molecular characters have strongly supported the assertion that the Sequoioideae are monophyletic. Most modern phylogenies place ''Sequoia'' as si ...
