 and PUeolaria hreripes, Berk. & Rav.. for the teleutoform, and 

 the latter name has been coiuiuonly used, though the signifi- 

 cance of the specific appellation is unintelligible or incorrect, 

 for the })edicels are conspicuously long. Upon comparing 

 specimens and descriptions of European and American plants, 

 it does not ap{»ear that the latter can be maintained as a dis- 

 tinct species, hence the name previously given to the former 

 has here been adopted (I'irdo fcirh/iifhi, D. C. Flore Franc. 

 [1815], Vr. p. 71). The teleutospores are not at all different, 

 but in the poor specimens at hand of the European uredo- 

 spores, the spiral arrangement of the prominences cannot be so 

 well made out; however, Schroter (Hedwigia XIV. ( 1875J, 

 p. 170) does not find any difference between them. Doul)tless 

 there is none. 



It is peculiar that a difference of oi)inion should exist as to 

 which of the forms is the teleutospore. In these specimens the 

 yellowish fragile-stalked form appears alone in the collections 

 of .luly. in those of August this is well scattered but present, 

 while the thick-walled long-stalked form may be found in sori 

 still mostly covered by the epidermis, and later (October) only 

 this last is found.
