316 BOTANY. 



beaded and sub-globose ultimate segments; these are nuked above, and 

 beneatli commonly bear at their centre a single broad scale; involucre 

 formed of the much incurved margin. — Sp. Fil. ii, p. 103, t. 107, 13. 



Texas and New Mexico (Findler, 1015, Wright, 2126), extending northward to the mountains of 

 Colorado (Hall $■ Barbour, G91, Brandegee), and westward to Arizona (Parry, Palmer) and California 

 (San Gabriel Mts., Brewer, and near San Bemardiuo, Parry). The scales are veiy conspicuous, at 

 first white, but gradually becoming brown, the lint spreading from the point of attachment. They are 

 considerably larger than the ultimate segments, and those I have examined seem to he entire, broadly 

 o\ ate and decidedly acuminate. I find that apart from these scales the pinnules or segments are per- 

 fectly glabrous on the under side, ( hus distinguishing the species from small forms of C. myriophylla, with 

 which it has occasionally been confused. 



Cheilanthes flevelandii, D. C. Eaton. 



Rootstock creeping, covered with narrow rigid dark-brown scales ; 

 stalks scattered, 2-6 inches long, dark-brown, wiry, when young scaly, but 

 at length nearly smooth ; fronds of mature plants 4-6 inches long, ovate- 

 lanceolate, tripinnate ; smooth and green above, beneath deep fulvous-brown 

 from the dense covering of closely imbricated ovate-acuminate elegantly 

 ciliated scales growing on the ultimate segments as well as on the midribs 

 and rachises; segments otherwise naked, nearly round, flattish, £— h a line 

 broad, the terminal ones larger, the margin narrowly recurved and un- 

 changed in texture and color. — Bulletin of the Torrey Botanical Club, 

 vi, p. 33. 



Mountains near San Diego, Mr. Daniel Cleveland. Imperfect specimens of what seems to be the 

 same thing were sent in 1875 from San Bernardino by Dr. Parry. The fronds average a little larger than 

 those of C. Fendleri, and are similarly divided into innumerable minute rounded segments, either densely 

 placed or rather lax, as in that species. The scales are only half as large as those of C. Fendleri, are 

 made up of much more tortuous cells, are in the mature frond of a very deep but bright cinnamon- 

 brown, and bear near the base or along the lower part a few very long ciliary projections, which are 

 often curved upwards and visible from the upper surface of the frond. It may prove that this is only a 

 form of C. myriophylla, but as the scales of the frond are smaller and very closely imbricated, it is per- 

 haps best for the present to regard it an distinct.

Cheilanthes niyriophyila, Desvaux. 



Rootstock very short, clothed with dark-brown narrow rigid scales ; 

 stalks tufted, 2-6 inches high, castaneous, wiry, covered with partly decid- 

 uous pale-brown narrow appressed scales and woolly hairs intermixed ; 

 frond 3-8 inches long, oblong-lanceolate, smooth and green or deciduously 

 pilose above, beneath matted-tomentose and. densely clothed with pale- 

 brown or ferruginous narrowly ovate-lanceolate ciliated spreading scales,
