Initial intro rant is 12 minutes and rambles on about the Prednisone worsening ADD, getting smacked in the face with Poison Ivy while filming magic mushrooms in Mexico etc.

A conversation with Dr. Lucas Majure from Florida Natural History Museum about evolution in the Cactus Family, Hummingbird-Pollinated Tree Prickly Pears, why one genus of Cactus wears a damn Fez (just like the shriners), the subtle nuances of Dogtooth Karst, Weird-Ass plants from Cuba that only grow on a certain soil type, and much more.
