Liparis Loeselii, Spiranthes latifolia, Goodyera repens, Arethusa bulbosa, Calopo- 

 gon pulchellus, Pogonia ophioglossoides, Habenaria tridentata, H. virescens, 

 "H. bracteata, H. Hookeri, H. orbiculata, H. ciliaris, H. leucophita, H. lacera, 

 Cypripedium spectabile and C. acaule. Of these the following are confined ex- 

 clusively to the northern tier of counties : Goodyera repens, Arethusa bulbosa, 

 Habenaria tridentata, H. virescens and II. hyperborea. 



The following are reported only in the region south of the above named line: 

 Microstylis ophioglossoides, Liparis lilii folia, Corallorhiza innata, Habenaria fim- 

 briata and H. peramrena. Habenaria fimbriata is confined exclusively to counties 

 bordering on the Ohio river. 



Habenaria virescens and Goodyera repens are reported only from Steuben 

 County, and need verifying specimens to support the reference. 



Three species, viz., Arethusa bulbosa, Habenaria tridentata and H. hyper- 

 borea, are reported exclusively from the western portion of the State, yet it is a 

 noteworthy fact that all three come from Lake County, and are doubtless ex- 

 clusively northern species. In all probability a careful study of the flora of the 

 northeastern counties would show no division between the eastern and western 

 species.
