Draft:Flora of Colorado

The Flora of Colorado is well known, with scientific description and collection of its plants beginning in the early 19th century and being largely completed a century later.[1]

The first collector of plants to reach Colorado was the medical doctor with the Stephen H. Long Expedition of 1820, Edwin P. James. The expedition crossed over the South Platte River heading into Colorado on 23 June 1820 and headed toward Fort Smith in Arkansaws on 12 August.[2] In between

The flora of Colorado is well documented and rich in diversity because it spans three floristic regions, the North American Prairies Province of the North American Atlantic Region, the Great Basin Floristic Province of the Madrean Region, and the Rocky Mountain Floristic Region. There are approximately 2677 species and 645 varieties or subspecies recorded as growing in Colorado.[3]
