Pi)iiis Banksianu Lambert. "Sand barrens, Lake County, Ind., May 13, 

 1876." ( E. J. Hill.) This is the only record for the gray or northern scrub pine 

 in the State. The specimens sent the Survej' establish the species as a member of 

 the State tiora beyond question. The inclusion is an extension of the reported 

 range from Southern Michigan to Northern Indiana. It is a fact that in all prob- 

 ability more new forms will be added to the State flora by a careful study of our 

 forest trees than from any other group of plants, if we except, perhaps, the 

 water plants. For various reasons forest forms have received less attention and 

 are more i)Oorly represented in existing herbaria than any other. It is especially 

 urged that during the ensuing season specimens of all forest trees be furnished 

 the Survey by those interested in the work. 



Orchidaeetv. Our knowledge of the occurrence and distribution of the various 

 orchids of the State has been very greatly increased during the past year, a fact 

 due largely to the labors of Messrs. Hill and Van Gorder. Both of these gentle- 

 men have studied definite regions for years and have placed the Survey under 

 many obligations for their careful and courteous responses to the many requests 

 for information. I have asked Miss Alida M. Cunningham to collate the facts at 

 hand, which she has done under the title ^'Distribution of Orchidacea' in Indiava," 

 and reference is hei-eby made to that article (These Proc, p. — ). I wish also, in 

 this connection, to express the thanks of the botanical division of the Biological 

 Survey to Miss Cunningham for the patient and efficient work she has done in the 

 study and comparison of critical forms, which has done much to expedite the 

 work of the division and has added greatly to the value of its final report. 



Tojieldia (iluti)umi Willd. " Moist sands. Pine Station, Tnd., .July 28, 1875. 

 (E. J. Hill.) The State Catalogue refers this species to the " northern tier of 

 counties." This, however, is the only station in the state from which I have been 

 able to secure herbarium specimens. It is included in the Flora of Noble County 

 by W. B. Van Gorder (18th report of State Geologist, p. 66, ) as growing in 

 "moist grounds along the Elkhart river in Orange township, and is represented 

 in Mr. Van Gorder's private herbarium. I know of no other stations in which 

 the species occurs. The recorded range of the plant is "moist grounds, Maine to 

 Minnesota, and northward ; also south in the Alleghanies. 



Tri(/l(>chin marifinia L. "Wet sands, border of slougli. East Chicago, June 

 13, 1893." (E. J. Hill.) This species has been added to the state flora through 

 the close work of Mr. Hill, who has recorded the only station for Indiana. The 

 species is easily distinguished from the other members of the genus by its fruit of 

 six carpels. The assigned range of the plant is, "salt marshes along the coast, 

 Labrador to N. J., and in saline, boggy or wet places across the continent."
