of the flora are only local or occasional. A third class includes escapes 

 from cultiA'ation. the inclusion or exclusion of which is largely a matter 

 of individual judgment. The number of species added is much smaller 

 than I had reason to expect in view of the fact that the original catalogue 

 was based almost wholly upon accessible herbarium specimens, it being 

 felt that in the absence of such verifying material the enumeration would 

 lose much of its value. This rule led to the temporary exclusion of some 

 of the forms which are noAv definitely reported and verified by accessible 

 material. 



SPECIES TO BE ADDED TO CATALOGUE. 



Dryopteris spinulosa (Retz.) Kuntze. (Aspidium spinulosum Sw. ) 



Eeported from Wells County by C. C. Deam, and from Wabash County by J. 

 N. Jenkins. In fruit June 11. 

 Panicum sphrerocarpon Ell. Round-fruited Panicum. 



Porter County (E. J. Hill). 

 Panicum jlexile (Gattinger) Scribn. Wiry Panicum. 



Lake County (E. J. HillS 

 Panicum verrucosum Muhl. Warty Panicum. 



Porter County (E. J. Hill). 

 Bromus iectorum L. Downy Brome Grass. 



Lake County (E. J. Hill). This seems to be the western limit of this form, 

 which in favorable localities becomes a troublesome weed. 

 Agropyron repens glaucum (Desf. ) Scribn. (A. glaucum R. and S. ) 



Lake County (E. J. Hill). 

 Cyperus Houghtoni Terr. 



Lake and Porter Counties (E. J. Hill). 

 Eleocharis Robbinsii. Oakes. 



Porter County (E. J. Hill). 

 Psilocarya nitens (Vahl) Wood. Short-beaked Bald-rush. 



Porter County (E. J. Hill). 

 Psilocarya scirpoides Torr. Long-beaked Bald-rush. 



Porter County (E. J. Hill). Britton and Brown give the range of this plant 

 "In wet soil, Eastern Massachusetts and Rhode Island." The above 

 citation extends the range of the plant far to the west. I have not seen 

 the plant, but admit it because of the well known discriminative accur- 

 acy of Mr. Hill.
