Rhodesia. — Matabeleland (Oates); Victoria Falls, common in the

Genus 31. Hypolepis Bernh. 
Sori small, round, equal, situated in the sinus between 
two lobes, or where a sinus might be expected if further 
divided. Indusium membranaceous, small, round, equal, 
covering the capsules. Veins free. A small genus closely 
allied to Cheilanthes, and formerly included in it. The sori 
are placed at the base of the sinus, and terminate a side 
veinlet ; while in Cheilanthes they terminate the principal 
veinlet, i.e. the one leading into a lobe. Most of the species 
belong to the southern tropics, and a few extend to New 
Zealand and South Africa. 
127. Hypolepis sparsisora (Schrad.) Kuhn. 
Plate 1 1 7. Part of frond, nat. size, b Pinnule, enlarged. 
Rhizome two to four yards long, half-inch diameter, sub- 
terranean, branching occasionally, clothed with brown scales, 
and sending up at intervals of about a foot erecto-patent, 
deltoid fronds, two to five feet broad, three to eight feet long, 
on a stout stipe two to three Teet long, which is more or less 
rough with raised points, or when young set with abundant 
long spreading white hairs below. The fronds, which die 
down to the ground in winter, develop at first as three almost 
equal and diverging branches, but when the central one is 
fully developed, the frond is three to four-pinnate in the usual
