megaflora

Megaflora (from Greek μέγας megas "large" and Neo-Latin flora "plant life") refers to an exceptionally large plant species; Jared Farmer defined the term as "the largest vascular plants of a particular region, habitat, or epoch". Examples of megaflora include the Sequoioideae of California, Pando (a large clonal organism of quaking aspen located in Utah), and a number of extinct plant species from the Mesozoic.

Megaflora (along with megafauna) are often seen as charismatic and have wide public appeal, making them particularly useful as the symbol or flagship species of conservation efforts.
