222 ARTHUR-BISBY— TRANSLATION OF SCHWEINITZ'S 



(440. II. [^cidium] Ranunculi (abortivi). Frequent on the round 

 radical leaves, almost devoid of spots.) 



Represented by three radical leaves of Ranunculus abortivus L., 

 2.5 cm. broad, mounted, well covered beneath with aecia, and by an 

 empty packet labelled inside " ^cidium Ranunculi nitidi Salem," 

 and outside iEcidium ranunculiat Ran abortivi Sal & Bet." 



Schweinitz was correct in his first list in considering this fungus 

 distinctive, and in error later in assigning it to Link's inclusive 

 species. It occurs only in x^merica, and in the eastern United States 

 only on Ranunculus aboi'tivus, being the fecial form of Puccinia 

 Eatonicc Arth. 



*2876. 66. C. A. Cimicifugatum, L.v.S., very beautiful, rather rare on leaves 

 of Cimicifuga racemosa, Bethlehem. Where found almost all 

 leaves are infested. 

 C. spots large, orbicular, yellow, bullate. Pseudoperidia on the lower 

 surface, concentric, very long, cylindric, apex at first closed, 

 then subfimbriate. Spores orange, becoming white. 



Represented by parts of three leaves, each part about 4 cm. 

 long, mounted, showing considerable groups of very long cylindric 

 peridia, and by an empty packet labelled inside " ^cidium Actasse 

 near Easton on Delaware very rare," and on the outside " .^cidium 

 Acteseatum LvS Bethl," with Acteaeatum crossed out and " Cimici- 

 fugatum " substituted for it. 



This imperfectly known rust is even at the present time a rare 

 form. It is probably hetercecious, and may belong to some grass 

 rust. Schweinitz changed the name to JEcidiuui (Ccvonia) cimici- 

 fugatum on page 309 of the same work. 



*2877. 67. C. A. Hibisciatum, L.v.S., on leaves of Hibiscus militaris, Beth- 

 lehem, cultivated, not rare. 

 C. spots orbicular, yellowish, confluent. Pseudoperidia irregularly 

 but densely scattered, delicate, yellow. Spores not compact but 

 loose, yellowish. 



Represented by one obliquely triangular-ovate leaf, 3 by 5 cm., 

 mounted, having many groups? of ?ecia, and by an empty packet 

 labelled " C?eoma ^'Ecidium Hibiscatum LvS in H. militaris Beth." 



The rust is the secial stage of Puccinia hibisciata (Schw.)
