330 WILLIAMS: PERUVIAN MOSSES 
A few stems with one capsule were found mixed in with 
Breutelia tomentosa. This is evidently the same species as that 
collected by Weddell in Peru and named, apparently in manu- 
script only, Bartramia nutans by Montagne. It is also the same 
as my Bolivian collection, No. 2825, referred to Breutelia nutans 
(Mont.). 
BREUTELIA TOMENTOSA (Sw.) Schimp. 
San Miguel, Urubamba Valley, about 1,800 m., May, 1915; 
Cook & Gilbert 988; Lucumayo Valley, 1,800-3,600 m., June, 
1915, Cook & Gilbert 1320. 
POGONATUM CAMPYLOCARPUM C. Miill. ; 
Lucumayo Valley, 1,800-3,600 m., June, 1915, Cook & Gil- 
bert 1322. 
POGONATUM POLYCARPUM (Schimp.) Broth. 
Araranca, south side of La Roya Pass, about 4,100 m., April, 
1915, Cook & Gilbert 177 and 182. 
POLYTRICHUM ANTILLARUM Rich. 
Torontoy, Urubamba Valley, about 2,400 m., June, I9I5, 
Cook & Gilbert 1194; Lucumayo Valley, 1,800-3,600 m., on wet 
earth, June, 1915, Cook & Gilbert 1378. 
HEDWIGIA ALBICANS (Web.) Lindb. 
Temple of Viracocha, near Tinta, about 3,500 m., April, 1915: 
Cook & Gilbert 204; Ollantaytambo, about 3,000 m., May, 1915: 
Cook & Gilbert 5or. 
HEDWIGIDIUM IMBERBE (Sm.) B.S.G. 
Urubamba, on rocks, 2,900 m., J uly, 1911, Foote 18; Ollantay- 
tambo, 2,750 m., July, 1911, Foote 19; Temple of Viracocha, neat 
Tinta, about 3,500 m., April, 1915, Cook & Gilbert 2044. 
BRAUNIA CANESCENS Schimp. 
Near Calca, on rock, April, 1915, Cook & Gilbert 245; Ollan- 
taytambo, about 3,000 m., April and May, 1915, Cook & Gilbert 
473, 502, and 503. This species has been considered scarcely 
distinct from B. cirrifolia (Wils.) Jaeg., but it seems to me to be 4 
rather smaller species with more closely imbricate leaves. The 7 
leaves also, below the apex of the stem, are broader in the uppe? 3 
part, often slightly obovate, and more abruptly narrowed to the 
pale apex of blade and hair point. B.cirrifolia has leaves rather Ms
