Coal Creek, Part II

We saw Astragalus nuttalliana again here. In fact, there were two varieties: var. austrinus and var. pleianthus. (We're sorry to say that we can't tell from the photo which one this is....)

Two species of Nama grow here. Nama hispidum is a small, hairy plant with purple flowers. It's a highly variable plant, with many different leaf shapes and pubescence types known.

We were excited to find Nama jamaicense. This plant is known from our home Brazos Valley area, but we'd never seen it in the wild. (A flat, dry herbarium sheet doesn't do it justice!) We were so glad to meet it face to face.

A very familiar plant was Drummond Phlox, Phlox Drummondii. Several subspecies grow in Texas. This is the familiar all-pink subspecies drummondii..

Two very nice ferns grow on the rocks along the creek. Woolly Lipfern, Cheilanthes tomentosa has fronds that are very densely pubescent on the undersurface. Compare it with C. alabamensis that was growing on the foot of the outcrop.

Southern Maidenhair Fern, Adiantum capillus-veneris, cascades down the rockface. This fern is common in central Texas wherever there are waterfalls.
