of M. inexicanum Mitt., but I have not had an opportunity to form 

 a personal opinion on this point. 



MACROMITRIUM PYCNOPHYLLUM Card. Rev. Bryol. 36: 108. 1909; 



37: 19. 1910 



Morelia: Campanario (7568, 7635) ; Cerro Azul (4535- 4545, 4548, 

 4777) ; Cascade de Coincho (4717 in part). 



Often found intermingled with the following species. Sometimes 

 the association is so intimate and the stems so entangled that the 

 separation of the two species is almost impossible. 



MACROMITRIUM TORTUOSUM Schimp. in Besch. Prodr. Bryol. Mex. 45. 1871 



Morelia: Cerro Azul (4557, 4777a, 4791, 4792); Cascade de 

 Coincho (4712, 4717 in part) ; Campanario (7464, 7524, 7528, 7532, 

 7536, 7560, 7567, 7634a, 7636, 7638). 



Determination only probable. I had the choice between M. tor- 

 tuosuiii Schimp. and M. Schhnperi Jaeg. (ilf. Uexuosum Schimp.). 

 Although not absolutely identical with M. tortuosum, the specimens do 

 not dififer enough to be separated. On the other hand, I do not know 

 M. Schimperi, and the descriptions of the two species in Bescherelle's 

 Prodromus are insufficient to permit distinguishing one from the 

 other. 



CRYPHAEACEAE 

 CRYPHAEA ORIZABAE Schimp. in Besch. Prodr. Bryol. Mex. 70. 1871 



Veracruz: Cordoba (s. n.). 



Determined from description. I distinguish this species from C. 

 filiformis (Sw.) Brid. by the leaves, which are larger and very entire 

 at the apex, and have larger cells. 



CRYPHAEA APICULATA Schimp. 



Puebla: Hacienda Batan (4970). 



The leaves are entire, as described by Bescherelle, and not " sehr 

 klein gezahnt," as described by Brotherus. 



CRYPHAEA ATTENUATA Schimp. in Besch. Prodr. Bryol. Mex, 72. 1871 



Morelia: Cerro Azul (4798); Valle de Mexico: Desierto {Bro. 

 Amablc 1223, 1237).
