As of September 2016, the International Union for Conservation of Nature (IUCN) lists 2493 critically endangered plant species, including 145 which are tagged as possibly extinct or possibly extinct in the wild. [1] [2] 11% of all evaluated plant species are listed as critically endangered. The IUCN also lists 89 subspecies and 70 varieties as critically endangered.

Contents

Additionally 1674 plant species (7.6% of those evaluated) are listed as data deficient , meaning there is insufficient information for a full assessment of conservation status. As these species typically have small distributions and/or populations, they are intrinsically likely to be threatened, according to the IUCN. [3] While the category of data deficient indicates that no assessment of extinction risk has been made for the taxa, the IUCN notes that it may be appropriate to give them "the same degree of attention as threatened taxa, at least until their status can be assessed." [4]

Phragmipedium is a genus of the Orchid family (Orchidaceae) and the only genus comprised in the tribe Phragmipedieae and subtribe Phragmipediinae. The name of the genus is derived from the Greek phragma, which means "division", and pedium, which means "slipper". It is abbreviated 'Phrag' in trade journals.

Flora of Lebanon Wikimedia list article

The flora of Lebanon includes approximately 2,600 plant species. Situated on the eastern coast of the Mediterranean Basin, Lebanon is a reservoir of plant diversity and one of the world's biodiversity hotspots for conservation priorities. Endemic species constitute 12% of the Lebanese flora; 221 plant species are broad endemics and 90 are narrow endemics. Important Plant Areas (IPAs) featuring the country exceptional botanical richness were defined in 2018.

This is a list of plants found in the Sierra de Manantlán Biosphere Reserve. The reserve straddles the Mexican states of Colima and Jalisco. It is located in the transition between the Nearctic and Neotropical realms and encompasses parts of the Sierra Madre del Sur, with a wide range of altitudes, climates and soils. The effects of tectonic and volcanic activities and erosion are notable within the reserve.
