no verifying specimens. It is scarcely possible tiiat this can be the only station 

 for the plant, since its range fairly covers the State. 



Utriculnria resupinatu B. D. Greene. "Sandy margins of ponds, Whiting, 

 Lake County, Ind., Ang. 16, 1883." (E. J. Hill.) This collection, upon which 

 is based the extension of the range of this form in the Gth Edition of Gray's Man- 

 ual (p. 7;^5c. ), is only one of the many evidences of the critical work done by 

 Rev. E. J. Hill and proof of the value of a long continued study of a single area. 

 This same form was sent me last summer by W. B. Van Gorder from north shore 

 of Bear Lake, Noble County, thus extending its local distribution. 



Utrieuloria purpurea Walt. "Shallow ponds, Pine Station, Lake County, 

 Sept. 13, 1879." (E. J. Hill.) This is another form shown by Mr. Hill to be a 

 member of the State Hora. This station for the plant is somewhat remarkable be- 

 cause it is so far inland. While the range is "ponds, Maine to Florida," it is 

 limited by the additional statement, usualli/ near the cotust. 



Utricularia (/ibba L. "Sandy, wet margins of ponds. Pine Station, Lake 

 County, Sept. 13, 1879." (E. J. Hill.) While this plant would be naturally ex- 

 pected within our range, it has been but rarely collected in the State. The speci- 

 mens furnished by Mr. Hill being the only ones I have seen from Indiana. It is 

 especially desirable that close observations should be made in favorable localities 

 in order that the distribution of these forms within the State may be determined. 



Corispermum hyssopifoliuin L. "Dry, sandy ground. Pine Station, Ind., Sept. 

 4, 1893 " (E. J. Hill.) The only reported station for this species. No great 

 extension of its range throughout the Stale need be expected, since in our range 

 it seems confined to the beaches of the Great Lakes, although farther west and 

 south it is not so restricted. The form is presumably from the west, judging from 

 available data. 



Salsola Kali L., var. Tragus. This plant has undoubtedly obtained a sufficient 

 foothold in the State to be included in its flora. It is, however, very doubtful if 

 its spread will be sufficiently rapid to give it rank among our worst weeds. The 

 plant is definitely reported from Clarke, Lake County, by E. J. Hill, and from 

 Avilla, Noble County, by W. B. Van Gorder. Both collections are labelled 

 "along railroad," indicating very clearly the method of introduction into our 

 State rtora. An examination of both specimens leads me to question the reference 

 of the Lake County specimen. It does not agree in many particulars with the 

 Noble County specimen, which latter is very plainly the typical variety 'I'raf/UK, 

 and so far as I am able to judge agrees more nearly with Salsola Kali. The exten- 

 sion of the range — "sandy seashore, New England to Georgia"— by the addition 

 of "and along shores of Great Lakes" is a very natural one. but is apparently
