186 PROCEEDINGS OF THE AMERICAN ACADEMY 



Cheilantiies viscosa, Link. In the San Miguelito Mountains 

 (926 SchatFner) ; 990 Parry & Palmer. PellcBa glauca, J. Smith, 

 seems in no way different from this. 



Cheilantues tomentosa, Link. At Soledad, Coahuila (1395, 

 139G). Also a form with very large pinnules from the Caracol 

 Mountains (1391). — Var. Eatoni, Davenport. ( C. Ealoni, Baker.) 

 At Soledad, Coahuila (1394), at Guajuco, Nuevo Leon (1393), in the 

 mountains east and south of Saltillo (1397, 1398), and in the San 

 Miguelito Mountains (910 Schatfner) ; 999^ Parry & Palmer. 



CiiEiLANTHKS GRACiLLiMA, Eatou. A form mucli larger than the 

 usual Californian specimens. In the Sierra Madre, south of Saltillo 

 (1390). 



Cheilanthes cinnamomea. {Myriopteris rufa, Fee.) In the 

 San Miguelito Mountains, San Luis Potosi (911 Sehaftner), and in 

 the San Rafael Mountains (914 Schaffner). The species of the 

 Mi/riopteris gTouji of this genus are very perplexing, and in the ab- 

 sence of autlientic specimens often very ditficult to identify. The 

 plant here referred, not without hesitation, to one of Fee's species, has 

 an elongated cord-like rhizoma, fronds 3 to 8 inches long, 3-4-pinnate 

 with closely set minute bead-like pinnules, smooth and green above, 

 but beneath heavily covered like the rhachis with a coarse entangled 

 tomeutum of a bright-ferruginous color. Some of the smallest fronds 

 have the lower pinnules " ecartees " as Fee describes them. C. cin- 

 namomea, as understood, differs from the large form of C gracilUma 

 in the elongated rootstock and in the much coarser woolly covering of 

 the pinnules beneath. The name rufa is preoccupied in this genus. 



Cheilanthes Lindheimeri, Hooker. In Uvalde Canon, 90 miles 

 northwest of San Antonio, Texas (1392), and in the Escobrillos 

 Mountains (937 Schaffiier) ; 999 and 999^ Parry & Palmer. Schaff- 

 uer's specimens were marked " ^lyriopteris cheiloglyphis, Fee," a plant 

 unknown in American herbaria ; but they do not at all agree with 

 Fee's description. 



Cheilanthes myriophylla, Desv. In the Escobrillos Mount- 

 ains (912 Schaffner), and in the mountains about Morales (915 

 Schaffner) and San Miguelito (916 Schaffner); 987 and 988 Parry 

 & Palmer. 



Cheilanthes Clevelandii, Eaton. In the Escobrillos Mountains 

 (913 Schaffner). The coi'd-like rhizoma is wanting, but the fronds 

 are evidently like those of the San Diego specimens. 



Cheilanthes earinosa, Kaulf. In the San Kafael Mountains 

 (963 Schaffner).
