252 ARTHUR-BISBY— TRANSLATION OF SCHWEINITZ'S 



Both rust and host appear identical with those respectively that 

 go under the same names at the present time. 



*2930. 26. P. Asteris, L.v.S., a handsome species, frequent on leaves of A. 

 paniculatus, Bethlehem. 

 P. spots flattened, bullate, yellow, not widely expanded. Sori very 

 dense, subconcentrally placed, beautifully fuscous. Spores rather 

 loose, concolorous. 



Represented by a packet containing a short stem with three leaves 

 attached and also by ten much crumpled, similar, ovate-lanceolate 

 leaves, all with long, slender petioles, and all sparsely bearing telia. 

 The packet is labelled " Cseoma (Ur) Asterum LvS Bethl in Ast. 

 paniculat," with the first two words crossed out and " Puccinia " 

 substituted. 



The leaves are doubtless Aster cordifolius L., and the rust is the 

 short-cycle form first given the name Puccinia Asteris by Duby in 

 1830, two years before the Schweinitz name was published. Doubt- 

 less the early collection on Aster paniculatus, this being its most 

 common host, was entirely given away, leaving only a later collection 

 on A. cordifolius. 



♦2931. 27. P. Kuhnise, L.v.S., common on the leaves of Kuhnia, Bethlehem. 

 P. without anj' spots. Sori amphigenous, pulvinate, densely aggre- 

 gated, blackish brown. Spores rather large, loose, long pedi- 

 celled. A Phragmidium? 



Represented by an original packet labelled on the inside " Uredo 

 Kuhnise in K. eupator Bethl & Salem," with " Uredo " crossed out 

 and " Puccinia " substituted, and on the outside " Puccinia Kuhnise 

 LvS Beth." The packet contains a tiny fragment, 2 by 33/2 mm., 

 bearing a few large telial sori. The peculiar glands and hairs make 

 the host unmistakable, and the amphigenous sori with their ellipsoid 

 teliospores fully justify the record. 



The rust is not common eastward, Schweinitz's record being the 

 only one known to the writers east of Wisconsin and Indiana, 

 although in the middle west, especially between Illinois and the 

 foothills of Colorado, it is not infrequent. In the Carolina list i^M/im'a 

 is mentioned as host for a rust (see no. 2844), and the earliest label 

 on the packet reads " Bethl & Salem," but the packet was probably
