distributed, and most of the species vary considerably in accord- 
ance with surroundings. 
Synopsis of the species. 
30. C. pteroides. Frond deltoid, three-pinnate, glabrous, pinnules 
stalked, half-inch long, oval, entire ; involucre distinct, one to each 
veinlet. 
31. C. capensis. Frond deltoid, two-pinnatifid, glabrous, pinnules half- 
inch to one inch long, sessile, decurrent, lobed ; involucres numerous, 
many to a lobe. 
32. C. depauperata. Frond lanceolate, two-pinnate, four to twelve inches 
long, a quarter to half-inch broad, glabrous above ; pinnae deltoid, lobes 
linear, tomentose on the under surface. 
33. C. hirta. Frond broadly lanceolate, three-pinnatifid, hairy ; pinnae 
ovate-lanceolate ; lower pinnae reduced ; frond and segments plain. 
Var. contracta. Frond narrowly lanceolate, three-pinnatifid, 
hairy ; frond and segments much infolded. 
34. C. parviloba. Frond lanceolate, three-pinnatifid ; pinnae lanceolate, 
glabrous ; stipe hairy ; pinnules deltoid. 
35. C. multifida. Frond deltoid, three to four pinnatifid, glabrous ; seg- 
ments nearly flat, slightly involved, with two to four membranous 
indusia to each lobe. 
36. C. induta. Frond ovate-lanceolate, three-pinnatifid, glabrous above ; 
segments hairy and tomentose on the under surface, involved, and with 
no distinct indusia. 
37. C. Bolusii. Frond deltoid, four-pinnatifid, glabrous above, segments 
very small, much involved, glandular on the under surface. 
30. Cheilanthes pteroides. Sw. The Myrtle Fern. 
Plate XXIV. Natural size. 
Crown procumbent, paleaceous. Frond coriaceous, three- 
pinnate, triangular, nine to fifteen inches broad, twelve to eighteen 
inches long, on a naked shining nearly black stipe nine to twelve 
inches long. Lower pinnae largest, deltoid, simply pinnate toward 
the point, two-pinnate below. Other pinnae mostly simply 
pinnate, and decreasing to the simply pinnate point cf the frond. 
Pinnules shortly stalked, glabrous, oblong, rounded or cordate at 
the base, rounded at the apex, a half to three-quarter-inch long, 
two to five lines broad, crenate. Rachis shining, but woolly at 
the axils, or at first all along. Sori small, roundish, or crescent-
