FROM THE CAMEROONS MOUNTAIN AND RIVER NIGER, 151 
late ovatis acutis, theca in pedunculo elongato gracili pallido elongato- 
ovali cylindracea, operculo longe subulirostrato. 
Hab. Cameroons Mountain, alt. 8000 feet, on the ground, Mann. 
In size and habit like the larger states of A. estivum, Hedw., but with 
its upper leaves narrowed at the base, and a rather more dense areolation.

SYRRHOPODON, Hook. et Grev. 
S. ARMATUS, sp. nov. Dioicus, late cæspitosus, caule brevi ramoso 
radicellis purpureis tomentoso, folis e basi erecta paululo latiore 
utrinque dentibus setiformibus 3-6 ciliata lineari-lanceolatis paten- 
tibus concavis apice acutatis integerrimis, nervo angusto dorso aspero 
in mucronem excurrente, cellulis calymperoideis spatium subellipticum 
foli basis totum occupantibus, inde ad apicem minute rotundatis 
obscuris, dorso papillosis, theca in pedunculo gracili bilineari ovali, 
operculo subulato subzequilongo, peristomio dentibus brevibus. 
Hab. Bagroo River and banks of the Nunn, on dead bark, Mann. 
Very near to S. spiculosus, Hook. et Grev., and S. trachyphyllus, Mont., 
but with leaves more narrow at the base (scarcely wider than the upper 
portion), the nerve evidently excurrent, the marginal cilia at the base 
longer. 
S. LAMPROCARPUS, sp.nov. Caule elongato parce ramoso, foliis e 
basi erecta oblonga vaginante patentibus anguste subulato-lanceolatis, 
nervo pallido dorso levi percurrente, margine in parte vaginante lato 
pallido, inde ad apicem angustiore serrulato, cellulis calymperoideis 
totum partis vaginantis occupantibus inde ad apicem minutissimis ob- 
scuris, perichetialibus conformibus apicibus ad basin thece cylin- 
dracez vermicularis attingentibus, pedunculo rubro, operculo longe 
subulato, peristomio dentibus rubris angustis, calyptra fere basin 
thecee tegente. 
Hab. Fernando Po, Mann. 0. 
Stems one inch and a half high, slender, apparently not growing in a 
tufted manner. Leaves very pale green, rather remotely inserted, unal- 
tered in position when wet or dry; including the base, they are about 
three lines long. Whole plant a little more robust than S. tristichus, Nees 
ab E., with which it nearly agrees in general appearance.
