What does "havardi" mean in reference to Big Bend?

I've seen a few species that are from that area with some form of havardi in their scientific name, but I can't seem to find an answer on where this comes from. I figured there might be a few people here with enough experience with the region to know where it came from.

Thank you so much! I tried googling it so many different ways and never got an answer.

There’s a few names that always pop up with plants like George Engelmann, Charles Parry and John Torrey. Feels like everything is names Engelmannii.

Poor Heinrich Schott got the short end of the Agave stick.
