 Mountains (928 Schaffner) ; 1006 Parry & Palmer. Western Texas 

 to Arizona (Wright, King, Rothrock, Rusby, etc.). This is the

 the New Mexican specimens. The veins are free in some fronds, and 

 netted in others, from the same lot of specimens. Klotzsch's name has 

 priority over the others.

 997 Parry & Palmer. 



NoTHOL^NA BRACHYPUS, J. Smith. In the region of San Luis 

 Potosi (998 Parry & Palmer). The hairs of the lower surface are

 guelito Mountains (946 Schaffner) ; 993 and 994 Parry & Palmer.
