98 CRYPTOGAMIA ANTARCTICA. [ Fuegia, the 
Herbarium), as also the description (in ZEtheog. p.80), prove it to be identical with O. Zudwigii, Schwaegr., which 
therefore ought to have been named O. coarctatum. 
Prats CLII. Fig. 11.—1, plant of the natural size; 2 and 3, leaves; 4, seta, theca, &c.; 5, calyptra; 6, theca ; 
7, teeth of peristome :—magnified.

t.xxi. Bruch et Schimper, Bryol. Europ. fasc. 2-3. p. 23. t. 12. 
Haz. Hermite Island, Cape Horn; on rocks and branches of trees near the sea, always barren. 
This species often bears, at Hermite Island, jointed conferva-like gemmee among the young leaves, 
4. ORTHOTRICHUM Magellanicum, Mont., in Voy. au Pole Sud, Bot. Crypt. p. 290. t. 20. f. 2. 
Haz. Strait of Magalhaens; M. Jacquinot.

1. Macromtrrium longipes, Schwaegr.; Suppl. II. 2. p. 131.? Orthotrichum longipes, Hook. Musc. 
Exot. t. 24. 
Var. ramis gracilioribus elongatis, foliis luridis erectis lineari-oblongis plicato-carinatis nervo excurrente. 
Has. Hermite Island, Cape Horn, Mr. Davis; barren. 
Perhaps a distinct species ; but though different in aspect, obvious characters are wanting to distinguish it from 
the Hookerian specimens. 
12. WEISSIA, ۰ 
1. Weissıa erispula, Ludw.; vid. Part 1. p. 127. t. lviii. f. ii. Dicranum interruptum, Brid. Bryol. 
Univ. vol. i. p. 438. Bryum pilosum interruptum, ‚Dill. Muse. p. 376. t. 47. f. 38. 
Has. Hermite Island, Cape Horn; rocks on Kater's Peak, alt. 1,000—1700 feet, growing in tufts, 
Apparently identical with the European plant, and also found in Campbell’s Island. 
2. WEISSIA contecta, Hook. fil. et Wils.; vid. Part. 1. p. 127. t. Ixiii, f. iii. 
Has. Kerguelen's Land ; barren, on rocks. 
Also a native of Campbell’s Island. 
3. Wuissta acuta, Hedw.; Muse. Frond. vol. iii. t. 85. Hook. et Tayl. Muse. Brit. p. 87. t. 14. 
Var. 8. theca subrotunda, seta breviore arcuata, peristomii dentibus latioribus cribroso-pertusis. 
Has. Falkland Islands; at Port Louis, barren. Hermite Island, Cape Horn; var. 8, on wet rocks in 
and near water-courses, in St. Martin's Cove; wet sandy banks on Mount Foster. 
We have no specimen of Weissia acuta B., Wahlenb. (Fl. Lapp.), which seems to differ, according to the 
description very little from our moss. The capsule of ours is turbinate when dry, with a very wide mouth. The 
seta is sometimes equally short in British specimens. 
4. Waıssta stricta, Hook. fil. et Wils.; caule ramoso, foliis subfalcatis lanceolato-setaceis rigidis cana- 
liculatis integerrimis crassinerviis nervo longe excurrente, theca subrotunda, operculo rostrato. (Tas, 
CLIL. fig. IV.)
