| Identification | Curtis's Spurge is a delicate green plant less than 1.5 feet tall, with widely to moderately branched upper half, these short-branched and bearing small inflorescences. Leaves are linear to narrowly lance-shape and tapered to both ends. Floral glands (resembling petals) are short and white, yet conspicuous. E. exserta is very similar in size and shape, but is overall a grayish green color, and the floral glands are maroon or red-purple. Curtis's Spurge is frequently seen in sandy pinelands, especially in the Sandhills, and though a "wispy" plant with very narrow leaves and slender stem and branches, is noticeable to an observer in sandy barrens as long as there aren't taller plant to distract attention! | |
