Falklands, etc.] FLORA ANTARCTICA. 405 



Hab. Kerguelen's Land ; on rocks near the sea, not uncommon. 



Caules imciales, laxe casspitosi, ramosi, Folia suberecta, conferta, rigida, siccitate vix crispata, nervo lato 

 crasao longe excurrente instructa, luteo-viridia ; perickaetialia longiora, basi latiora, erecta, convoluta. Seta 

 3-linearis, erecta vix tortilis, pallide rufa. Iheca suberecta, subrotunda, ore contracta, rufo-brunnea, demum atro- 

 rubens,vernicosa. Peristomii dentes 16, parvuli, conniventes, pyramidati, obtusiusculi, liuea media notati. Oper- 

 culum conico-rostratum, capsular longitudine, rostro curvato acuto. Calyptra dimidiata, subventricosa, fusco-lutea. 

 Floresceutia monoica. 



We know of no described species with whicli 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. 



Plate CLII. Fig. TV. — 1, tufts of the natural size; 2, leaf; 3, youug seta ; 4, capsule; 5, the same before 

 the fall of the calyptra : — all magnified. 



5. Weissia tortifoUa, Hook. fil. et Wils.; caule ramoso, foliis patentibus flexuosis siccitate crispatis 

 lineari-subulatis canahculatis integerrimis nervo excurrente, perichsetialibus brevioribus convolutis, seta 

 brevi, tbeca subrotunda, opereulo rostrato. (Tab. CLII. fig. V.) 



Hab. Kerguelen's Land, common on gravelly banks, from the sea to 1,000 feet. 



Caules subunciales, dense casspitosi, ramosi. Folia patentia, varie flexuosa, siccitate crispata vel tortuosa, nervo 

 gracdi excurrente instructa, lutescenti-viridia, inferiora fuscescentia ; perichastialia breviora, ovata, acuminata, con- 

 voluta. Seta vix 2-hnearis, crassiuscula, fusco-brunnea. Theca erecta, subrotunda, rufo-brunnea, verrucosa, demum 

 indurata. Peristoma dentes 16, pyramidati, conniventes. Operculum conico-rostratum, eapsulae longitudine, rostro 

 obliquo. Calyptra cucullata, capsulam sequans illamquc obtegens, brunnea. Floresceutia monoica. 



Very closely allied to Weissia striata (nobis), but differing in the crisped widely spreading leaves, which are 

 only half as long as in that species.
