It is Charles Wright's No. 821, collected between Western Texas and New Mexico. It has been sent from New Mexico also by Dr. Bioelow, Mr. SciioTT and Dr. Seguin, and was found near Camp Bowie, in Ari- zona, by Professor Rotiikock and Mrs. Sumner. It has recently been collected on the journey from San Luis Potosi, in Mexico, to San Anto- nio, Texas, by Dr. Parry (No. 992). Description:—This fern has, like most of the ferns which grow in the clefts of rocks, a creeping and rather short root-stock, well covered with scales. The scales are two or three lines long, lanceolate, and appressed to the root-stock. They consist of a very broad and rigid, dark-brown and shin- ing midnerve, which has a narrow border of more delicate and paler cells on each side. The stalks are clustered at the end of the root-stock, and are dark-brown, shining, wiry and nearly erect. Near the base they bear a few scales, which are shorter and broader than those of the root-stock, and have a narrow midnerve. The section discloses a single roundish fibro-vascular bundle, having the ducts which it contains ar- ranged in a somewhat lunate form. The fronds have an outline between that of a pentagon and that of a five-pointed star. They consist of a middle portion of a rhomboid-ovate form, supported on a short but narrowly winged stalk, and two lateral divisions, which are sessile. The middle part is pinnatifid nearly to the midrib into a few oblong-lanceolate crenate and often sub-falcate.
