Tortilla ( Syntrichia ) Andicola Mont. Unduavi, 8000 ft. Octo¬ 
ber, 1885 (3120). Sterile plants only collected. 
Large sterile specimens answering the description given in the 
Ann. Sci. Nat. (Series 2, 953) and compared at the Jardin des 
Plantes with the type collected by D’Orbigny near La Paz, in the 
Bolivian Andes. 
Tortilla ( Syntrichia ) aculeata Wils.? Mapiri, 5000 ft. April, 
1886(3123); Sorata, 10000 ft. 
Compared at Kew with Spruce, no. 144 and Jameson’s speci¬ 
mens from Pichincha, both cited by Mitten under the description 
of this species. Ours agree with Jameson’s better than Spruce’s 
no. 144, and it would seem as if the two were distinct or the 
species very variable. Bescherelle also seems to think there is 
room for separation here, as he says : “ T. aculeata Wils. affinior 
sed primo viso differt. Foliis integerrimis, magis papillosis, duplo 
longioribus, pilo valde longiore diversa, ut videtur—forsan species 
nova ? 
Tortula (Syntrichia) bipedicellata n. sp. Bescherelle, M. S. 
Mapiri, 5000 ft. May, 1886 (3123a). 
Plants in small yellowish-brown tufts; stems 1-2 cm. high; 
leaves not crowded, curled and twisted when dry, 3-4 mm. long, 
without a hyaline point, the vein stout and brown, but ending in a 
short mucronate point at the apex of the leaves; margins plane 
or rarely slightly revolute below; upper cells densely papillose, 
lower large, clear and oblong. Dioecious perichetial leaves not 
differentiated. Pedicels mostly two together, about 1 cm. long, 
straw-colored; capsules 3-5 mm. with a long beaked lid, straight 
or slightly curved ; mouth small, red ; peristome not developed. 
Closely related to T. glacialis Kze. Compared at Kew with 
Weddell’s no. 20, collected in Bolivia, province of Larecaja, June, 
1847, with which it agrees in the leaf characters but differs in hav¬ 
ing the pedicels more uniformly in pairs. There is a mixture 
also in this species at Kew, for the specimens collected by Lieb- 
mann on Mt. Orizaba and Poeppig in Chili are very different in 
aspect. Brescherelle says of them: “ Affinis T glacialis Kze., 
foliis tamen duplo-longioribus, ad summum planis haud undu- 
latis ; capsula geminore, peristomio non afformato.” 
Tortula fragilis Taylor? Sorata, 10000 ft. (3121).
