Halfleaf Sundrops
Calylophus serrulatus; Evening Primrose Family (Onagraceae)

This identification is only tentative. The stigma of this flower is cross-like, while Halfleaf Sundrops reportedly has a doughnut-shaped stigma. See Peterson Field Guide, Southwestern and Texas Wildflowers (Niehaus, Ripper & Savage- 1984), page 158. Otherwise, all the other features of this flower fit. Note especially the lancelike leaves with toothed margins, and the drooping sepals. Perhaps someone who reviews these images here will provide me with additional information on this fellow.

Photographed in the southeastern sector of the native portion of Fern Bluff Park on April 7, 2001.
