only one has as yet been met with in fruit; but the presence of 
these three closely allied species in such a circumscribed area is 
interesting, for it is only in Australia, Tasmania, and New Zealand ` 
that two certainly congeneric species are known to exist. To 
these are added descriptions of a few other curious species, chiefly 
from Madeira. 
MUSCI. 
ANGOTANGIUM, Schw. 
A. ANGUSTIFOLIUM, sp. nov. Caule brevi gracili, foliis patentibus 
linearibus basi paululo angustioribus concavis apice acutis nervo per- 
currente, cellulis basi paucis quadratis pellueidis sensim in minutas 
rotundatas subleves transeuntibus, perichetialibus ovato-lanceolatis, 
theca in pedunculo gracili obovata. 
Hab. Teneriffe, “ad rupes sylvarum,” Schmidt in Herb. Hooker. no. 46. 
Less than A. compactum, Schl., and softer. The leaves are about 
ten times as long as broad, pale green, subcrispate when dry; the 
cells very minute, but distinct. 
A. compactum occurs in Teneriffe and Madeira, and grows asso- 
ciated with Zygodon curvipes, C. Müller, a moss which is found 
also on the mountains of Abyssinia and does not appear "to differ 
from Z. cyathicarpus, Mont., so widely distributed in the southern 
hemisphere. 
GLYPHOMITRIUM, Brid. 
(Ptychomitrium, Schimp.) 
G. PULVINARE, sp. nov. Monoicum, pulvinatum, foliis patentibus incur- 
vis e basi subovata lanceolatis acutis nervo excurrente marginibus in- 
tegerrimis, cellulis basi paucis quadratis rectangulatis cito in parvas 
rotundatas approximatas transeuntibus diametro circiter les uncis 
metientibus, perichztialibus conformibus, theca in pedunculo trilineari 
obovata, operculo rostro theca dimidio breviore, peristomio dentibus 
brevibus solidis. 
Hab. Madeira, on rocks, Johnson. 
Growing in small hemispherical tufts of a dull dark green colour, 
much resembling G. erispatum, Bridel= Grimmia crispata, Hook., 
but with leaves having the cells of the upper portion much larger 
and those of the base not elongated. G. polyphyllum, Dicks., is 
abundant and very fine in Madeira. 
According to M. Schimper, Ptychomitrium, to which he refers 
G.polyphyllum and some other species, differs from Glyphomitrium 
in having the teeth of its peristome not approximated in pairs and
