Has. Kerguelen’s Land; on rocks near the sea, not uncommon. 
Caules unciales, laxe ceespitosi, ramosi. Folia suberecta, conferta, rigida, siccitate vix crispata, nervo lato 
crasso longe excurrente instructa, luteo-viridia; perichetialia longiora, basi latiora, erecta, convoluta. Seta. 
3-linearis, erecta vix tortilis, pallide rufa. Theca suberecta, subrotunda, ore contracta, rufo-brunnea, demum atro- 
rubens,vernieosa. Peristomii dentes 16, parvuli, conniventes, pyramidati, obtusiusculi, linea media notati. Oper- 
culum conico-rostratum, capsule longitudine, rostro curvato acuto. Calyptra dimidiata, subventricosa, fusco-lutea. 
Florescentia monoica. 
We know of no described species with which this can be confounded. It is somewhat allied to the European 
W. acuta, but the capsules are larger, of a firm texture, retaining their shape when dry. In Dr. Lyall's specimens the 
leaves are more falcate and the seta shorter. 
Prare CLII. Fig. IV.—1, tufts of the natural size; 2, leaf; 3, young seta; 4, capsule; 5, the same before 
the fall of the calyptra :—all magnified. 
5. Werssta tortifolia, Hook. fil. et Wils.; caule ramoso, foliis patentibus flexuosis siccitate crispatis 
lineari-subulatis canaliculatis integerrimis nervo excurrente, perichztialibus brevioribus convolutis, seta 
brevi, theca subrotunda, operculo rostrato. (Tas. CLII. fig. V.) 
Has. Kerguelen’s Land, common on gravelly banks, from the sea to 1,000 feet. 
Caules subunciales, dense ceespitosi, ramosi. Folia patentia, varie flexuosa, siccitate crispata vel tortuosa, nervo 
gracili excurrente instructa, lutescenti-viridia, inferiora fuscescentia; pericheetialia breviora, ovata, acuminata, con- 
voluta. Seta vix 2-linearis, crassiuscula, fusco-brunnea. Theca erecta, subrotunda, rufo-brunnea, vernicosa, demum 
indurata. Peristomii dentes 16, pyramidati, conniventes. Operculum conico-rostratum, capsule longitudine, rostro 
obliquo. Calyptra cucullata, capsulam sequans illamque obtegens, brunnea. Florescentia monoica. 
Very closely allied to Weissia stricta (nobis), but differing in the crisped widely spreading leaves, which are 
only half as long as in that species. 
Prare CLII. Fig. V.—1, tuft of the natural size; 2 and 3, leaves; 4 and 5, capsules :—all magnified. 
13. DICRANUM, Hedw.

dentibus angustis subintegris, operculo longirostro, (Tas. CLII. fig. III.) 
Var. 2. foliis secundis. 
Var. 3. caule graciliore, foliis brevioribus siccitate subflexuosis, nervo tenuiore.
