The plant has been found in but one locality in Stockbridge, under 
a thick spruce hedge near the village street, in dry ground. There 
were about twenty-five plants at this spot. The lady, who brought it 
to me, saw it there first in 1897. — RALPH HOFFMANN, Belmont, Mass. 
[Information as to the possible cultivation or artificial introduction of this rare 
orchid in New England, would be of much interest. — Ep. ] 
AN ANNOTATED LIST OF RARE OR OTHERWISE INTER- 
ESTING MOSSES OCCURRING IN OR NEAR PLYMOUTH, 
NEW HAMPSHIRE. 
A. J. GROUT. 
Tetradontium Browntanum (Dicks.) Schwaegr. On stones in a 
cave known as Devil’s Den, near the summit of Mt. Prospect, Holder- 
ness. ‘This cave is a slanting cleft in a ledge at the top of a line of 
cliffs. The plants of Tetradontium haven ot the flagelle of 7. repanda 
. and seem referable to 7. Brownianum. ‘They were growing upright on 
the moist stones near the top of the cave and were not inverted as is 
frequently reported. 
Polytrichum gracile Dicks. On knolls in swampy woods, with Z. 
Ohioense, at an altitude of about 1000 feet. The opercula had all 
fallen from the P. Ohioense at the time of collection (August 6), but 
several remained on the capsules of P. gracile, indicating that the 
sporophyte of the latter matures somewhat later than that of the 
former. 
Dicranum longifolium Ehrh. On stone walls near the summit of 
Mt. Prospect. The plants on the exposed stones at the top of the 
wall were markedly different from those at its base. The tufts were 
. more compact and darker colored; the stems were much shorter; the 
leaves were shorter with costa half the width of the leaf base, or even 
more. 
Dicranum viride (Sull. & Lesq.) Lindb. On decayed stumps, in 
woods, sterile. 
Oncophorus Wahlenbergit Brid. Moist soil, beside abandoned road. 
Grimmia conferta Funck. Along moist cracks of the under side 
of a rocky shelf, Mt. Prospect.
