OSMUNDA REGALIS L. 



Rare in the state. Two specimens, one well-fruited, 

 collected in 1891, the other sterile, collected in 1893, both 

 secured by Mr. Fred. Reppert in "swampy depressions on 

 sandy hills near Cedar river, Lake twp., Muscatine 

 county" are in the herbarium. Mr. Reppert notes that 

 they are being tramped out by cattle. 



OSMUNDA CINNAMOMEA L. 



The collection contains one fine fruiting specimen from 

 Lake twp., Muscatine county. Mr. Reppert collected it in 

 June, 1891, "in one of the frequent hillside swamps of the 

 sandy hills along the Cedar river." About twenty years 

 ago the writer collected fruiting specimens of this species 

 near Old Man's creek in Johnson county. Some of the 

 specimens were in the University herbarium for a time, 

 but they have disappeared. 



*"2?. ternatum Swz." {B. obliquum Muhl.) has been reported from 

 Fayette county ( Fink), and from Floyd county (Arthur), but the 

 University herbarium contains no specimen from Iowa.
