ORCHIDS OF CHESTERVILLE, MAINE. 
LILuIAN O. EATON. 
For the past five summers it has been especially interesting to the 
writer to search for orchids in Chesterville, Maine. As the town 
contains several bogs, many swamps, forests of varied character, a 
large sand-plain, and a long esker called “the Ridge,” the possibility 
of finding many species has seemed great. Nor has the result been 
wholly disappointing. To the present date, I have found twenty-six 
representatives, a specimen of each being in my herbarium, while it 
seems not unreasonable to hope a few more may be discovered. 
The list, with localities of the plants, is as follows. 
Microstylis ophioglossoides, Nutt. In wet pasture, growing with 
Vaccinium macrocarpon ; also in evergreen swamps. 
Liparis Loeselii, Richard. Not unusual in old fields. 
Corallorhiza innata, R. Br. In wet soil of deciduous woods, found 
but ónce, in June, 1897. 
C. multiflora, Nutt. Several stations in evergreen swamps. 
Listera cordata, R. Br. Plenty in cold wooded swamp, near Ches- 
terville Plains. 
Spiranthes cernua, Richard. The various forms abound in swales 
and meadows also by roadsides. 
S. gracilis, Bigelow. Occasional by roadsides and in dry pastures. 
Goodyera pubescens, R. Br. Fairly common in rich woods. 
G. repens, R. Br., var. ophioides, Fernald. A single plant was 
found in deciduous woodland in 1898. In 19or and 1902, several 
were found in a cedar swamp. 
G. tesselata, Lodd. Occurs both in evergreen and hardwood 
| growths, not rare. 
Arethusa bulbosa, L. On a sphagnum bog, found two successive 
seasons; but not more than twenty-five plants in all. The only sta- 
tion yet known in the county. 
Calopogon pulchellus, R. Br. Grows freely on at least three bogs. 
Pogonia ophioglossoides, Nutt. Abundant in meadows, bogs and 
damp swales. 
Habenaria tridentata, Hook. Roadsides and fields, occasional. 
H. virescens, Spreng. In an old field, the only station so far known 
in the county. In 1899 and 1900, I found two or three plants each
