Campbell’s Islands. | CRYPTOGAMIA ANTARCTICA. 37 
laxe imbricatis erecto-patentibus obovatis obtusiusculis apices versus parce crenato-dentatis basi angustatis, 
margine anteriore recurvo decurrente, calyce elongato-obovato basi nudo 4-5-alato ore contracto denticulato. 
(Tas. LXIII. Fig. IV.) 
Has. Lord Auckland's group; on moist rocks, near the summits of the hills. 
Cespites subdensi, 2-3 unc. diametro, pallide straminei v. virescentes. Caules 3 unc. longi, subrigidi, simpli- 
ciusculi. Folia inferiora integra v. interdum unidentata, superiora apices versus plus minusve irregulariter crenato- 
dentata, omnia conformia, basi angustata antice decurrentia, apices versus rotundata, cellulis distinctis. Calya ter- 
minalis, subpedicellatus, erectus, basi attenuatus, foliis caulinis vix duplo longior, alis 4-5 angustis planis v. rugosis, 
duobus oppositis interdum opacis, ore subtubuloso, crenato v. 4-fido, tandem fisso, foliis pericheetii propriis nullis. 
In external appearance this species very closely resembles the former, the leaves are, however, more loosely 
cellular, and in the structure of the calyx it widely differs. The Peruvian Pl. gymnocalycina, Lind., (Spec. Hep. 
p. 48. t. 10) has the calyx equally naked below and of a similar outline, but it is smooth and furnished with only 
two very obscure ribs, its foliage also is perfectly dissimilar and the whole plant is much larger. The wings of the 
calyx are formed out of deep folds of its membrane.

16. JUNGERMANNIA fuscella, Hook. fil. et Tayl.; caule subceespitoso ascendente curvato vage ramoso, 
foliis laxe imbricatis patulis late oblongo-rotundatis basi obliquis subdeflexis siccitate verticalibus v. sub- 
crispatis, margine anteriore recurvo subdecurrente, posteriore in lobulum latum producto denticulato, calyce 
terminali obovato truncato deflexo foliis pericheetialibus breviore. (Tas. LXIII. Fig. V.) 
Has. Lord Auckland's group; in moist boggy places. 
Cespites late diffusi, 3-4 uncias diametro, luride olivacei v. fusco-atri. Caules 11—92 unciales, superne cur- 
vati, subgraciles, seepe reflexi, siccitate una cum foliis subcrispatis subsquarrosis rigidi. Folia latiuscula, dense 
cellulosa, opaca, areolis subpunctiformibus, luce transmissa pallide fusco-olivacea, marginibus integris v. plerumque 
margine posteriore denticulato, supremis interdum omnino sub lente denticulatis. 
In many respects this species resembles Montagne's P. pusilla (Voy. au Pole Sud, Bot. Crypt. tab. 16. f. 3), 
a species, judging from the plate, founded upon a young and imperfect specimen, and which we think exists in 
the Herbarium of the Expedition of a larger size. It differs from this in the deep serratures of the leaves, in the 
habit and colour and above all, in belonging (according to the figure) to a section having the leaves coadunate at 
the base, In the form of the foliage our plant more nearly resembles the P. hemicardia, nobis, but is very different 
in the disposition of the leaves on the stem. A few calyces were observed ; they are very uniform, shorter than the 
pericheetial leaves and concealed by them ; some are proliferous, the stem being produced through their axis and ex- 
serted : this abnormal state has been observed in J. Lyoni, Tayl., and in several species of mosses, as in Conomitrium 
Berterii, Montagne (Cryptog. Boliv. t. 3. f. 4).

tops, abundant.
