124 BRYOLOGY OF NEW ZEALAND. 
the same thing, but might possibly be 7. rubripes, the “ pedunculo flavo ” 
being the only character at variance with that species, but the description 
is not sufficiently detailed for certainty. 
The plant is widely distributed, and occurs in Tasmania and Australia. 
2. Tortella rubripes (Mitt.) Broth., op. et loc. cit. 
Syn. Trichostomum rubripes Mitt. in Handb. N.Z. Fl., p. 417 (1867). 
I judge this to be a rare species; Mitten described it from specimens 
collected by Kerr in an unspecified locality in New Zealand ; otherwise the 
only specimens I know are som reat Barrier Island, Hutton and Kirk, 
No. 151, in Mitten’s herbariu 
t is very distinct, the bates are oblong-lingulate from a wider, pale 
base, obtuse and cucullate at apex, with the nerve excurrent in a short 
mucro, the margins incurved above ; ; the hyaline basal cells ascend very 
markedly higher at rae ; the capsule is erect and symmetrical, not 
curved as in T. Knightii 
3. Tortella calycina (Schwaegr.) Dixon comb. nov. 
Syn. Barbula calycina mpgs ae Suppl. ii, Pt. 1, p. 63 ade 
Tortula calycina Hook. & Grev. in Brewster Edinb. Journ., 1, 
291 (1824); Handb. N.Z. Fl., p. 420. Tortula Walkeri R. Br. 
ter. in Trans. N.Z. Inst., vol. 30, p. 406. 
I think the proper place of this species is in Tortella ; the general habit 
either side of the stout, brown nerve aye ts a few rows of equally 
elongate but bright-golden — and these are marked with seriate papillae 
for some distance lower than they occur on the cells of the rest of the 
leaf-base, the papillae, in fact, fee reaching very near to the insertion 
of the leaf. The back of the nerve also is covered for the greater part o 
its length with fine and evenly distributed papillae 
e leaves are wide, concave, often involute, variable in the acuteness 
of the Soe but nearly aways having t the nerve excurrent in a longer or 
nee ee mucro. The seta is much longer Liat in the other species of the 
genu 
it is distributed throughout both Islands, and, indeed, has a wide 
ite throughout Australia, and also in Chile. 
vi is certainly, from Brown’s specimen, this species. 
A eg also gathered by Mr. James Murray in the Waitakarei Hills 
(Auckland), and referred by me to Trichostomum mutabile Bruch. (v. Journ. 
Linn. Soc. (Bot.), xl, 444), also belongs here. 
Dipymopon Hedw. 
As now understood this genus includes species having the general habit 
and foliation of Barbula, with margins usually recurved, never incurved, 
but differing in the peristome-teeth, which are short, erect, or slightly
