98 MR. W. MITTEN ON THE MOSSES OF 
Great confusion exists amongst the species of this group, whose cap- 
sules are inclined, bi-angular, plane or concave above and convex below, 
like those of Lyellia and Burbaumia. The figure in “ Hedwig Sp. 
Musc." fairly represents this moss, so far as relates to the entire plant; 
in the figure in “ Crypt. Antarct.” the capsules are not depicted with the 
two angles, and the outline of the leaf is not quite correct. M. C. 
Müller describes the capsule as “irregulariter 4-5 angulata,” but Moss- 
man's specimens are precisely like those from New Zealand and Fuegia. 
Bridel and Müller describe the perichztial leaves as cordate, but these 
appear to be not different iu form from the cauline. 
P. croceus (Mitten). Habitu staturaque P. Magellanici, caule sub- 
simplici foliis siccitate erectis appressis humidis e basi erecta convoluta 
oblongo-ovata inferne -cellulis elongatis teneris pallidis superne in 
maculani obcordatam basin fere dimidiam occupante intense croceo 
tinctis inde subito in minutas depressas incrassatas pallide fuscas trans- 
euntibus angustatis lanceolatis erecto-patentibus apice crassiusculo 
acutis lamellis obtectis margine superne dorsoque apice dentatis, peri- . 
chetialibus basi longiore tenerioreque convolutis parte angustata 
breviore vaginula filis fuscis emergentibus pilosa, theca in pedunculo 
elongato inclinata oblonga bi-angulata plano convexo, operculo ros- 
trato, calyptra glabra. 
Hab. Brazil, common on clayey banks, Gardner, no. 12. 
Leaves, when dry, more erect and appressed, and gradually narrowed 
from an ovate base in which the saffron-coloured spot appears to be 
uniformly present. 
P. HorRiDus (Mitten). Habitu formis communibus P. formosi, caule 
simplici, foliis rigidis siccitate vix mutatis e basi subovata erecta, 
convoluta, cellulis elongatis angustis subpellucidis subito superne in 
parvas depressas transeuntibus angustatis divaricatis lanceolatis apice 
sensim angustatis acutis lamellis obtectis marginibus e basi partis an- 
gustate dentatis erectis dorso apice parce subindistincte dentato, peri- 
chztialibus caulinis conformibus paululo angustioribus, theca in 
pedunculo elongato oblonga horizontali bi-angulata plano-convexa. 
P. Magellanicum, Hedw. Sp. Musc. t. xx. fig. 2. 
Hab. Hermite Island, Cape Horn, Dr. J. D. Hooker. Sandy Point, 
Magellan, Lechler, 1163. Falkland Islands, Dr. J. D. Hooker and 
Lechler, 97. 
Young leaves glaucous green, the older and nearly the whole plants 
ferruginous, stiff, and scarcely at all altered by drying, gradually narrowed 
at the apex into a bristly point, not obtusish as in P. Magellanicus, nor 
so abruptly narrowed from the dilated base, but gradually narrowed from 
a base of a subovate form,  Hedwig's fig. 2, J. c. excellently represents 
the leaves of this species; but the figure of the whole plant (fig. 1) is 
very different, and equally well depicts the species here understood as 
P. Magellanicus; and as both inhabit the same region, it may not be
