Rare new flower species at oasis

We were excited when a birder discovered Dark Star Milkvine (Chthamalia atrostellata) growing at the oasis. It's quite rare and localized. A lifer for us! 



My sister is convalescing from hip replacement surgery, but she managed to get herself into the location to see it. We collected a specimen for Dr. Powell, the expert on Big Bend plants.



Dr. Powell wrote this to my sister, "As far as I know, this would be the fourth documented locality in the world." (He's the author of this huge tome on plants.)

UPDATE: The name I first posted it by was Matelea atrostellata, but I have since learned the name has been changed to Chthamalia atrostellata. The four documented locations for it are two in the Christmas Mountains (including ours), one in Big Bend National Park (Cattail Falls), and one in Coahuila, Mexico. I have observed at least eight seedpods in our patch of them.
