PLATE XXI
SCOTT'S SPLEENWORT
The known stations of this curious little plant are usually in the immediate neighborhood of the Walking Leaf and the Ebony Spleenwort, of which ferns it is supposed to be a hybrid. The long, narrow apex occasionally forming a new plant, and the irregular fruit-dots remind one of the Walking Leaf, while the lustrous black stalk, the free veins, and the pinnate portions of the fronds suggest the Ebony Spleenwort.
Scott's Spleenwort matures in August. It is rare and local, except in Alabama. The fact, however, that it has been discovered in widely distant localities east of the Mississippi should lend excitement to fern expeditions in any of our limestone neighborhoods where we see its chosen associates, the Walking Leaf and the Ebony Spleenwort. To find a new station for this interesting little fern, even if it consisted of one or two plants only, as is said to have been the case at Canaan, Conn., would well repay the fatigue of the longest tramp.
