PAPERS GI\'IXr, RUSTS OF XORTII AM1:RICA. 219 



(445. 16. [/Ticiclium] Verbesinse Sz. 



A. oval. ratiRT tliick, small, pale reddish yellow, peridia few, 

 prominent, white. 



Frequent on Verbesina, Sigcsbeckia, and others. Spots four 

 lines in diameter. Spores simple, very small, pale, margins of the 

 peridia entire.) 

 (446. 17. [i?Ici(lium] Solidaginis Sz. 



A. effuse, rather large, peridia scattered, minute. 



Frequent on stems of Solidagos before flowering. Similar to the 

 preceding.) 



Neitlier specimens nor packets remain to represent these entries. 

 Schweinitz was right in putting the Solidago jecia with those on 

 Aster. They go witli the Astcr-Solidago-Erigcron-Carex combina- 

 tion lately passing under the name, Puccinia cxtcnsicola Plowr., 

 along with the preceding number, one belonging to the physiological 

 race, Puccinia Caricis-Astcris, and the other to that of P. Caricis- 

 SoUdaginis as abundantly indicated by cultures. The present ac- 

 cepted name is Puccinia Astenim (Schw.) Kern. 



He was also right in excluding A. Hclianthi-mollis, here given 

 under the subsequent number; Ijut he was wrong in retaining A. 

 Vcrbesincc. The Vcrhcsina ?ccia belong with the autoecious rust 

 Puccinia Verbesina Schw. (see no. 2925), a rust which is common 

 throughout the southern states. All collections of this species ap- 

 pear to be on V. occidcntalis (L.) Walt., which doubtless was the 

 host of Schweinitz's no. 445. Xo rust has yet come to hand on 

 Sicgcsbeckia (Actinonicris) , and the inclusion of the name must 

 have been due to an assumption not supported by collections. 

 Schweinitz claimed authorship of this species, hence places his 

 initials after the name, although Link was the first to write it in this 

 form, as Schweinitz was well aware. The name was written by 

 Schweinitz JEcidinm {Ca-ouui) astcratum on page 309 of his later 

 work. 



2871. 61. C. A. Helianthatum, L.v.S., Syn. Car. 450, frequent on H. mollis. 

 Rare in Pennsylvania. 

 (450. 21. [/Ecidium] Helianthi mollis Sz. 



A. oblong, thick, whitish, peridia congested, pale, spores oblong. 

 Frequent on the under side of the leaves of Hclianthus mollis;
