plants of the locality are Orobanche uniflora L,., Conopholis 

 americana (L,. f.) Wallr., Epifagus virginiana (Iy.) Bart., 

 Monotropa uniflora I/., M. Hypopitys Iy. 



13. Pogonia verticillata ( Willd.) Nutt. 



This species, noted in Vol. I of these Proceedings (1900) 

 as " locally abundant," must now be set down as rare and in 

 danger of extermination. In Manchester the station where it 

 was the most abundant has been transformed into a plantation 

 of Solanum tuberosum, doubtless more profitable to the owner of 

 the land than the orchids, but less interesting to the botanist. 

 At the other station the plants are greatly reduced in number. 

 From the station in Auburn but a single plant has been secured 

 since 1900. This was collected in September and bore two well 

 developed capsules. Doubtless there are other stations of the 

 species. When discovered it is to be hoped they will not be- 

 come too well known. 



14. Spiraiithes Romaiizofliaiia Cham. 



A station in Sandwich is located in open land near the top 

 of a high hill. The plants are associated with Botrychium 

 ramosum (Roth.) Aschers., B. obliquum Muhl., Lycopodium 

 clavatum (Iy.), var. monostachyon Grev. & Hook., Microstylis 

 unifolia (Michx.) BSP., and Potentilla tridentata Ait. 



15. Liparis liliifolia (Iy.) Richard. 



Collected in Manchester in 1895, but not found since. Two 

 plants set out in a "wild bed" survived and flowered three 

 years. The fourth year the plants were winter-killed, so that 

 there remains not even an herbarium specimen. 



16. Liparis Loeselii (Iy.) Richard. 



Thus far reported only from Concord, where it was once 

 collected by the compiler. Here, again, the march of agricul- 

 tural progress has seriously diminished if not exterminated the 

 species at the only known station.
