Urcdo Compositae. 205 



On leaflets and leaf stalks of Bidens pilosa L. 

 Queensland Brisbane, 1886 (Bailey 5 ). 



Part of the original specimen named by Dr. Cooke Uredo cichoracearum 

 DC., was kindly forwarded to me by Mr. Bailey, and on comparing it with 

 the above species in Exsicc. Syd. Ured., 1647, it was found to be the same. 

 Even the paraphyses, which are not recorded by Hennings, occurred in both. 



Puccinia bidentis Diet, and Holw. was described in the Botanical 

 Gazette, XXIV., 32 (1897), on a species of Bidens in Mexico, and probably 

 is the complete stage of this uredo. The original species was founded on 

 Bidens pilosa from Brazil.

Uredospores oval or irregularly pear-shaped to spathulate,

 longitudinally striate, average thickness 1 J // ; pedicels relatively 

 short, hyaline, and continuous with spore. 



III. Teleutosori similar but brownish. 



Teleutospores intermixed with uredospores, bright orange, 



oblong to oblong-clavate, smooth, fragile, constricted at septum, 



rounded at apex, generally tapering slightly towards base, 62-90 



x 18-28 /uL- } pedicel hyaline, persistent, short, up to 56 ^ long.

rounded at both ends, 60-68 x" 18-22 p.

This species was originally described as Uromyces asteris, but on extended 

 critical examination of the type material I placed it in the genus Uredo on 

 account of the number of the equatorial germ-pores. Since then additional 

 material has been found, showing it to be a Puccinia.
