5. ANDREXEA mutabilis, Hook. fil. et Wils., vid. Part 1. p. 119. pl. lvii. f. ii. 
Var. y, subsecunda ; foliis laxioribus inferioribus secundis. 
Var. 9. uncinata ; folis dissitis falcato-secundis. 
Has. Falkland Islands; both varieties, abundant. 
The var. 8. of this species is a Lord Auckland's group and Campbell Island plant. 
6. AxpREXA laxifolia, Hook. fil. et Wils.; caulibus laxe ceespitosis parce ramosis, foliis lanceolato- 
subulatis obtusiusculis concavis enerviis ramulinis falcato-secundis caulinis erectis subsecundis laxe imbri- 
catis, pericheetialibus elongatis ovato-lanceolatis convolutis, theca exserta ovato-oblonga. (Tas. CLI. fig. IV.) 
Var. B. minor ; theca subexserta. 
Has. Hermite Island, Cape Horn; not rare, on moist rocks in the higher parts of the Island. Var. ۰ 
on rocks near the sea. 
Caulis vix uncialis. Folia ramulorum conferta, falcato-secunda, luteo-viridia; caulina dissita, majora, vix 
secunda, subamplexicaulia. Florescentia monoica : flos masculus primo terminalis, folia perigonialia rotundo-ovata, 
acutiuscula, concava. Antheridia 6. Paraphyses numerose, duplo longiores. Theca siccitate turbinata, basi pallida.

7. ANDREAA subulata, Harvey; vid. Part 1. p. 119. pl. lvii. f. i. 
Var. B. rigida; folis minus falcatis crassioribus luridis. 
Has. Hermite Island, Cape Horn, and the Falkland Islands; not uncommon. 
The Auckland and Campbell Island variety differs slightly from the above. 
Subgen. Acroscuisma, Hook. fil. et Wils. (Theca cylindracea, e basi ad medium et ultra indehiscens, apicem 
versus tantum in valvulis 4 vel 8 fissa ;—an genus proprium ?) 
8. ANDREASA (Acroschisma) Wilsoni, Hook. fil.; caule laxe ceespitoso elongato ramoso, foliis ramulorum 
undique patentibus squarrosis spathulato-lanceolatis obtusiusculis caulinis erectis laxe imbricatis ovato- ' 
lanceolatis basi angustatis amplexicaulibus omnibus enervibus concavis marginibus inflexis, pericheetialibus 
elongatis elliptico-oblongis convolutis, theca exserta cylindracea apicem versus fissa. (Tas. CLI. fig. IIT.) 
Has. Hermite Island, Cape Horn; on maritime rocks near the spray of rivulets, rare. 
Caules sesquiunciales, graciles, erecti, per intervallos breves innovantes, subdichotomi, steriles vage ramosi, 
rami patentes. Folia ramulorum lanceolata, basi subamplexicaulia, erecta, deinde patula, squarrosa, apice subin- 
curva, obtusiuscula, lateribus inflexis, luteo-viridia, caulina majora, erecta, infra medium repente angustata, flaves- 
centia, enervia, areolis majusculis elongatis. Florescentia monoica: antheridia circiter 11, paraphysibus numerosis 
longissimis. Zheca elongata, maxima, inferne integra, badia, apice in valvulis 4 vel 8 fissa. 
Allied to Andreea laxifolia, but differing in the remarkable capsule and also in the form of the leaves, which 
do not taper gradually from the base, but are widened near the middle. ,

In addition to the former remarks on the structure of Sphagnum, we would observe, that the spirally lined 
cellules of the leaves do not constitute the proper parenchyma. The cellules, which contain the chlorophyll, are
