Campbell’s Islands. | CRYPTOGAMIA ANTARCTICA. 15 
lity, and indeed throughout the three islands of New Zealand, they abound. Wherever they grow they invariably 
affect shade and shelter. The European genus Orthotrichum, on the other hand, of which there are several Tasma- 
nian examples, is very rare in New Zealand ; and in Lord Auckland’s group and Campbell’s Island, as in the Falk- 
land and other Antarctic Islands, the species court exposure, growing on black and exposed rocks, enduring the full 
power of such solar heat as those regions afford during the day, and of the frost, wind, and nocturnal radiation at 
other times. Under these circumstances, their foliage is of a peculiarly hard and almost horny consistence, espe- 
cially when dry. 
Prare LVIII. Fig. I.—1 and 2, tufts of the natural size; 3, cauline leaf; 4, upper leaf from near the peri- 
chætium; 5, theca; 6, peristome; 7, a tooth; 8, calyptra; 9, calyptra, in a very young state, adherent with the 
vaginula, split open, exposing the enclosed seta, which is erroneously represented as bulbous; 10, the same, entire, 
surrounded by pistilla ; 11 and 12,calyptra, showing the base inflexed and attached to the summit of the vaginula :— 
magnified.

Has. Campbell’s Island; on exposed rocks from 600-1200 feet above the level of the sea, abundant. 
After a very careful comparison of the Campbell’s Island plant with specimens of W. crispula from Snowdon, 
we are at length satisfied of the specific identity of the two. It is still uncertain whether the W. erispula of Hooker 
and Taylor be the same as that of Hedwig. The characters of the latter and of W. cirrata, as given by Schwaegrichen 
(Supp. vol.i. pt. 1. p. 75.), differ very slightly. Of 77. cirrata both Hedwig and Bridel remark, “ folia marginibus reflexis 
aut inflexis,” the former we find constantly to be the case, in which respect the plant differs essentially from erispula. 
It is more than probable that the Moss from Snowdon, figured by Dillenius (Hist. Musc. t. 47. f. 38.), and quoted 
by Bridel as a synonym of his Dicranum interruptum, is the JF. crispula of Hooker and Taylor, which may well be 
considered by Bridel, a Dicranum, having the habit of that genus, and the peristome being unknown to him.
