Since the homology of the stamen, and the bract subtending 

 the seed bearing scale is evident, the^contention is still concern- 

 ing the homology of this extra strltcture the ovuliferous scale. 

 As an excellent summary of the numerous theories relating to 

 this subject is given in Coulter and Chdmberlain's Morphology of 

 Spermatoph3'tes, and as their repetition here would be entireh- 

 beyond the scope of this article, they may for convenience be 

 condensed into the two following simple propositions: 



First. The carpellate cone represents a regular l)ranch ; the 

 bract represents a leaf; the ovuliferous scale represents an 

 axillary stem with one or with two leaves all greatly reduced and 

 modified and it may or may not also represent the outer 

 integument. 



Second. The carpellate cone represents a dwarf branch like 

 the staminate cone ; and the ovuliferous scale is a ligular or 

 chalazal outgrowth of the megasporophyll or carpellate bract 

 which corresponds to the microsporophyll. 



The W'riter is inclined to favor the second view not onlv from 

 the sttidy of this monstrosity if any great importance is to be 

 attached to it but also for the same reason that Bessev gives in 

 his article in the Botanical Gazette, 33:157, namelv, that were 

 we to favor the first view we would have to assume that the 

 megasporangiate cones and sporophvlls in the closelv related 

 families of Finales, in some of which there is no ovuliferous 

 scale, are not homologous. 



NOTES FROM THE OHIO STATE HERBARHIM. IV. 



H. i\. G'LFASON. 



During the past year much of the unidentified herbarium 

 material has been studied, and a number of particular genera 

 have been worked over, with the result that several species of 

 flowering plants and ferns are to be added to the state flora. A 

 list of those species with notes on their distribution and their 

 distinguishing characters is here given. Some of them have 

 already been reported in this journal, but for sake of complete- 

 ness are listed again. In every case the w^riter is responsible for 

 their identification.

 Creek in Madison Covmty, Professor W. A. Kellerman. The 

 variety, as described by Fernald (Proc. Am. Acad. Arts and 

 Sci. 37:477. 1902.) differs from the species in the spikelets tawny 

 colored from the first, the narrower ovate perigynia about 2.5 

 mm. wide, and the ovate-lanceolate scales. The species has
