BOTANY. 
by Kaulfuss, although the next species has often been taken for it. Dr. Parry collected it near 
Monterey. Our specimens more than a foot high. The pinnules vary from 3 to 5-foliolate. 
Allosorus mucronatus, D. C. Eaton, in Sill. Jour. (2 d ser.) 22, p. 138. Cajon Pass, Sierra 
Nevada ; valley of the Sacramento, Dr. Stillman; California, Douglas. Our specimens are much 
larger than the plant described by Mr. Eaton, of which we have duplicates from that promising 
young botanist. It is often more than a foot high, the pinnae 10 to 20, and these pinnate, with 
the pinnules trifoliolate, somewhat verticillate, and crowded. It is much more common than 
the last species. 
Adiantum Ciiilense, Kaulf. Enum. p. 207; Hook. Fil. 2 , p. 43, t. 75, B. Deep ravines near 
Los Angeles ; also in Napa Valley and near the Redwoods, California ; March. 
Adiantum pedatum, Linn.; Torr. FI. N. York, 2, p. 487 ; Brack. 1. c. Redwoods; April. 
This differs somewhat from the plant of the Atlantic States, in being more slender, with the 
lobes of the frond broader at the base, and more deeply cut, but it can hardly be considered even 
as a distinct variety. 
Pteris lanuginosa, Kaulf. 1. c.; Hook. & Am. 1. c. Rocks near San Francisco Mountain^ 
Western New Mexico. 
Onychium densum, Braclcenridge, Ferns of the U. S. Expl. Exped. 1 ,p. 120, t. 13. Wet 
places, Grass Valley, California ; May. This neat and rare fern has much the appearance of 
Allosorus acrostichoides ; and Sir William Hooker says it must be removed to that genus or to 
Pellaea. It is beautifully figured in the work here quoted. 
Hypolepis Californica, Hook. Fil. 2 ,p. 71, t. 88, A. Mountains near San Gabriel, also near 
Marysville, California. Mr. Schott found it in Sonora. 
Cheilanthes Fendleri, Hook. Fil. 2, p. 103, t. 107, B. On rocks near the mouth of White 
Cliff Creek, Western New Mexico. 
Cheilanthes Bradburti, Hook, l. c. p. 97, t. 109, B. New Mexico, not rare. 
Cheilanthes vestita, Swartz; Hook. 1. c. p. 98, t. 108, B. On rocks in various parts of 
New Mexico. Extremely woolly when young. 
NoTOOHLiENA dealbata, Kunze, in Sill. Jour. (2d ser.) 6 ,y>. 83. Cheilanthes dealbata, Pursh, 
FI. 2, p. 675. Rocky hills, San Domingo, New Mexico. A beautiful and delicate fern, remark¬ 
able for the sharply zigzag branches of the rachis, and the white incrustation on the under 
surface of the frond. 
Gymnogramma triangularis, Kaulf. Enum. p. 73 ; Hook. & Grev. Ic. Fil. t. 153 ; Hook. FI. 
Bor.-Am. 2, p. 259. Hills and rocky places, Cajon Creek, and Redwoods. Young fronds 
sulphur-yellow underneath, (in dry specimens) ; the old ones brown. This species occurs also 
in New Mexico. 
W 7 oodwardia radicans, Willd. Sp. 5, p. 418 ; Hook, dc Am. Bot. Beech, p. 162 & 405. W. 
Chamissonis, Brack, l. c. p. 138. Cajon Pass ; March ; in fine fruit, probably of the preceding 
season. Mr. Brackenridge considers this to be distinct from W. radicans. Like W. Virginica, 
it belongs to the genus Doodia of R. Brown, which is now generally regarded as a section of 
Woodwardia. 
Cystopteris fragilis, Bernh.; Hook. I, c. p. 260. Aspidium tenue, Willd. Sp. 5 ,p. 280. 
Hill-sides, Yuba River, Redwoods, and other parts of California. The indusium at first has a 
long lacerate apex which lies over the joint, but which finally breaks off, leaving the broad 
cucullate or cup-shaped base. 
Aspdiuim munitum, Kaulf. Enum. p. 230 ; Hook. & Am. Bot. Beech, p. 162. Polystichum 
munitum, Presl.; Brack. 1. c. p. 203. Mountains near Oakland, and on hill-sides along the 
Yuba, Downieville, California. This species varies greatly in size, and in the length of its 
pinnae. It is allied to A. acrostichoides of the Eastern States. 
Aspidium (LASTRiEA) argutum, Kaulf. 1. c. p. 242 ; Hook. & Am. 1. c. Lastrasa arguta, Brack. 
1. c. p. 196. Mountain ravines, Oakland, Cajon Pass, and near San Francisco. This species
