The New Mexico Plant List
Includes taxa from following child checklists:
Authors: Harpo Faust
Locality: State of New Mexico
Abstract:

The New Mexico Plant List is the new working list of all taxa found in New Mexico. It uses Flora NeoMexicana 2020 as its basis, along with compiled FNM addendums, as well as other added taxa as they come along. SEINETs taxonomy clumps some infrataxa and doesn't recognize certain hybrids so the number's don't 100% add up to the most accurate diversity of New Mexico's Flora right now.
