422 FLORA ANTARCTICA. \Fuegia, the 



Hab. Falkland Islands; on shady clay-banks near the sea, at Port Louis (barren). Hermite Island; 

 common on mossy banks and on the trunks of old trees in the woods of evergreen beech, abundant in fruit. 



Very closely allied to Hookeria pulchella, nobis (part 1. p. 142. t. lxii) ; but the leaves are more erect, less 

 crowded, acuminated, with larger reticulations, thecae larger and decidedly cernuous. The calyptra in both these 

 species is fringed at the base. 



3. Hookeria flaccida, Hook. fil. et Wils. ; caule debili elongato erecto subramoso, foliis hnbricatis 

 erecto-patentibus ellipticis concavis obtusis subapiculatis integerrimis anguste marginatis evanidinerviis, seta 

 elongata lasvi, theca erecta obovato-oblonga, operculo rostrato, calyptra basi fimbriata. (Tab. CLV. fig. V.) 



Hab. Hermite Island ; in wet bogs on the hills, amongst other mosses and grass, very rare in fruit. 



Caules unciales ad triunciales, graciles, debiles, parce subpinnatim ramosi, rufo-fusci, ramis compressiuscuhs. 

 Folia laxe imbricata, erecto-patentia, flaccida, elliptico-oblonga, concava, obtusa, brevissime apiculata, inferiora sub- 

 obovata, omnia integerrima, margine tenui cartilagineo nervoque tenuissuno sub apice evanido instructa, sordide ac 

 palbde vii'idia, siccitate crispata, areobs parvulis rotundatis ; perichastiaba triplo minora, ovata, enervia. Seta 

 unciabs, vix tortilis, rubra. Theca erecta, obovato-oblonga, brunnea, subapophysata, ore subpatido. Peristoma 

 extend dentes lutei, incui'vi, trabeculati, linea media notati, intend processus albidi. Sporce minimae, luteo-virides. 

 Operculum comco-acuminatum, theca paulo brevius. Calyptra elongato-conica, acuminata, basi fimbriata, fusca, 

 capsulae dimidiam partem obtegens. 



A remarkably soft and debcate species, bearing much the same analogy to its congeners that Hypnnm strami- 

 nemn does to other Hypna.

4. Hookeria Magettanica, P. Beauv. ; caule ramoso erecto, foliis ovato-oblougis acuminatis marginatis 

 evanidinerviis, calyptra basi fimbriata. 



Hypnuji MageUanicum, P. Beauv. jEtheog. p. 66. 

 Hab. Strait of Magalhaens. 



An authentic specimen in Professor Arnott's Herbarium is closely allied to Hookeria flaccida, nobis. It differs 

 in having narrower acuminated leaves, which do not fully recover their shape after long immersion in water. 



c. Foliis emarginatis. 



5. Hookeria denticulata, nobis; vid. Pt. I. I. c. 145. tab. Lxii. f. 2. 



Hab. Falkland Islands ; in tufts of Riccia and Jungermamiia, on rocks near the sea, frequent (barren) . 

 Hermite Island, Cape Horn ; on the wet ground in woods, not uncommon (also barren). 



6. Hookeria cristata, Hedw. ; Sp. Muse. p. 211. t. 49. Schvaegr. Suppl. t. 278. A.B. 

 Hab. Hermite Island, Cape Horn. 



A solitary barren stem of this occurs in the collection of Hermite Island plants. 



31. HYPOPTEEYGIUM, Bridel. 



Our reasons for not having previously admitted this genus will be found in the former portion of this work. 

 We have seen since, that the male flowers are occasionally, though rarely, inserted beneath the accessory leaves, and
