This historical set of images needs a bit of context; the 3rd and 4th images show pages of my field journal which describe this "observation." A longer version of the story will be uploaded to a journal post.
Short version: This is the first ever photograph of Texabama Croton (Croton alabamensis var. texensis) on the day I showed the population to graduate student Steve Ginzbarg (U. Texas Botany Dept.; L in photo). I had discovered the shrubs during field work on May 31, 1989. I invited Steve Ginzbarg and John Gee (R in photo) to examine the plants on my next visit to the tract. Steve went on to name the plants as a new variety of Alabama Croton (Sida 15(1):41-52, 1992):

At the time, this was a private ranch. The croton became one of the focal plant Species of Concern for the Balcones Canyonlands Conservation Plan. The tract was later acquired for the Refuge of the same name, primarily for its population of Black-capped Vireos and Golden-cheeked Warblers, but also because this spot (where this photo was taken) is the "Type Locality" for Texabama Croton.

Quartz Mountain State Park, between parking lot and picnic table, shaded by a larger Sapindus drummondii. Growing in silty/sandy soil.
Single tree around 1 foot DBH, 15-20 feet tall. Bark broken into small chunks. Shallowly lobed - proximal lateral lobes often reduced or missing, such that the base of many leaves form a wide "U" shape; distal lobes ascending/pointing forward.
Twigs covered in very fine stellate hairs, not obscuring the twig surface, hairs densely distributed and often overlapping. Adaxial surface of leaves sparsely stellate-pubescent. Abaxial surface of leaves stellate-pubescent, obscuring the surface.
