Sori globose, dorsally iuserted beyond the forking or near the marginal summit of simple veinlets: indusium dimidiate-inferior, broadly embracing the sorus, persistent: receptacle prominent.—Leaves pinnatisect, rarely it-pinnatisect: veinlets of Cyathea, but the lowest mostly anastomosing. Several species, presenting the habit of Cyathea and Alsophila, I exclude from Hemitelia (c. g. II. capensis, Parkeri, guianensis, etc.), and, according to the insertion of their sori, would transfer them to Alsophila, near A. aspera: hence my Hemitelia is the same as Cnemidaria, Pr., while Hemitelia, Pr., is drawn to Alsophila. An exception however to this arrangement (as often occurs at the limits of Fern-genera) is presented by Alsophila Weigeltiana, Roem. (PI. Kappler. 1355) : for in this species 1 find the sori differently
