colour; the fruitstalks are about 2 inches long. In the areola- 
tion of its leaves it is intermediate between H. serpens and H.

N. sUBRECTA, sp. nov. Habitu N. trichomanoidis simillima, foliis 
patentibus obovatis basi angustatis apice rotundatis crenulatis apiculo 
brevi, nervo distincto ad Z evanido, cellulis minoribus, perichetialibus 
ovatis acuminatis apicibus denticulatis, theca in pedunculo elongato 
brevi ovali inclinata, operculo conico-acuminato, peristomio interno 
processibus perforatis cilis brevibus rudimentariis interpositis in 
membrana fere ad dentium medium exserta. ` 
Hab. Madeira, Santa Luzia Levada, about the roots of Thamnium alo- 
pecurum, Johnson. 
Very closely resembling N. trichomanoides ; but its leaves are 
scarcely at all curved, the nerve stouter and longer, and the lower 
portions of the leaves narrowed, so that their figure is uniformly 
obovate.

(Sciaromium.) 
Caulis primarius repens, radicans ; rami erecti, inferne simplices, 
superne pinnati pendulive prolixique, ramosi. Folia rigida, 
opaca, sublevia, uninervia. Cellule parvze, rotundate. Phyl- 
lidia nulla. Peristomium normale. 
L. SPINOSA, sp. nov. Caule primario repente radicante, ramis erectis 
rigidis superne ramosis frondem stipitatem formantibus, foliis obscure 
viridibus rigidis patentibus e basi ovata sensim longe subulatis, nervo 
crasso concolore in apice evanido, marginibus apice parce remote den- 
tatis alibi integerrimis, cellulis minutis rotundatis longitudine e, 
latitudine 3555 unciz circiter metientibus lzevibus. 
Hab. Madeira, Johnson and Mason ; Azores, Hunt, from Watson. 
In all respects very similar to Hypnum hispidum, Hook. f. et 
Wils. Crypt. Antarct. t. 61, but more robust, and with leaves having 
the nerve when closely examined not excurrent but vanishing in 
the upper portion of the points, which too are dentate. The cells 
are also rather smaller. 
Judging from the specimens, it would appear that well-deve- 
loped stems would be from 4 to 6 inches high, and less curved than 
is usual in H. hispidum. 
L. PROLIXA, sp. nov. Habitu L. spinose sed graciliore mollioreque, 
foliis patenti-erectis ovatis acuminatis leniter biplicatis, nervo lato 
erasso sub apice evanido, marginibus superne indistincte serrulatis,
