Escobaria missouriensis

Plants of Oklamoma

Introduction

Dr. JP Smith published an annotated checklist of all the plants of Oklahoma. He wrote, “My purpose is to provide a reasonably complete and up-to-date list of the vascular plants known to occur in Oklahoma.” He says “reasonable” because there might be some plants he missed, but only a few. He was very thorough.

Details

The list is considered annotated because he determined the status of the plants: N = native, E = endemic, I = introduced and naturalized; A = annual, P = perennial, S = shrub, SS = subshrub, T = tree, and V = vine. There are well over 2000 plants listed and he verified each one.

His report is long and interesting. He found numerous plants from various plant families including 20 species and subspecies of cacti. He also found lots of agave relatives.
