Rootstock stout, short, densely chaffy with rigid slender striped and concolorous bright brown scales. Stipes tufted, 4'-8' long, rather stout, densely brown- tomentose even when mature; blades oblong-lanceo- late, 3-pinnate, 6'-i8' long, densely tomentose, espe- cially beneath, with brownish-white obscurely artic- ulated hairs; pinnae and pinnules ovate-oblong or oblong-lanceolate, the ultimate pinnules distinct, usually obovate, about i" long, the terminal ones sometimes twice as large as the others, the reflexed margin forming a narrow continuous indusium. On rocks, Virginia to Georgia, Texas, Arizona and Mexico. July-Oct. Webby Lip-fern. 19. NOTHOLAENA R. Br. Prodr. Fl. Nov. Holl. 1: 145. 1810. Small rock-loving ferns, mainly of arid or semi-arid regions, the blades of various shape, 1-4-pinnate, the under surfaces hairy, densely tomentose or scaly, or in some species covered with a white or yellow waxy powder. Sori roundish or oblong, borne near the margin upon the free veins, at or near their extremities, soon more or less confluent laterally in a broad or narrow marginal band. Indusia wanting, the revolute margins at first covering the sporanges in some species, the sporanges often partially concealed otherwise by the hairy, scaly or waxy covering of the under surface. [Greek, meaning spurious cloak, no proper indusium being formed.] About 50 species of wide distribution. Besides the following numerous other species occur in the southwestern United States and Mexico. Type species : Acrostichum Marantae L. i. Notholaena dealbata (Pursh) Kunze. Powdery Notholaena.
