Barton Holland Warnock (1911–1998) was an American botanist and leading authority on flora of the Trans-Pecos area and northern Chihuahua Desert.
In 1946 Warnock joined the faculty of Sul Ross State College and a year later was named biology department chair.
He worked there for more than 50 years until retirement, during which he continued collecting various plant species in the region.
Warnock died from a heart attack at the age of 86 on June 9, 1998[3] while driving a car near Alpine.
The Barton Warnock Environmental Education Visitor Center, a state park near Lajitas in Presidio County, Texas, also bears his name and houses his extensive collection of plant specimens.
