the two species eae as new by C. Mueller in Hedwig., 1898, but from 
the eee there can be no shadow of doubt that they belong here. 
rispulum is ssatleipislied from R. ptychophyllum at once by the 
leaves, ert ie are not plicate, though when dry the strong carinate nerve 
may sometimes give this appearance; in any case they have not the 
numerous deep and narrow plicae of that species 
. crispulum is widely distributed throughout the Subantarctic regions 
of both ee I have lately recorded it from several localities in 
South Afri 
The va t.ergpan is recorded in the Handb. N.Z. Fl. from the North 
Island, coll. Colen ut I have seen no specimens which I should refer 
to it in the pe ened te at Kew and the British Museum. The Stewart 
Island plant referred to above is ts nearest approach I have seen; but 
I suspect it may be found on some of the higher mountains. There is, 
however, a specimen in Hooker’s herb. “ Bryum ater, New Zealand, 
a 2646,’ determined by Mitten as pic aegrte rupestris H. f. & W., and I 
esume collected by Hooker, which is no doubt correct, even showing the 
chormobemaisn transverse cell ssablatidnd: But the data as to locality are 
vague.

A fine species, like the most robust, yellowish forms of R. crispulum, 
but known at once by the numerous Ago sharp plicae of the leaves, which 
are only shortly diaphanous at the t

spinulose-serrate hair-points, is the only form found in New Zealand; i

however, occur at the Cape of Good Hope, so that the eeaphical

of this, as well as New Zealand specimens named R. fasciculare Brid., in
