B. sUBERECTUM, sp. nov. Monoicum, B. Nipalensi simillimum, foliis 
e basi angustiore elliptico-spathulatis acuminatis, nervo in mucronem 
excurrente, marginibus ubique late cartilagineis a basi ad medium 
revolutis inde ad apicem remote serratis, cellulis parvis late oblongis, 
theca in pedunculo elongato inclinata pyriformi sub ore parvo con- 
stricta, operculo conico acuminato, peristomio Brachymenii. 
Hab. Fernando Po, Mann. 
Closely resembling B. Nipalense, but with leaves more narrowed at the 
base, more broadly marginate. The operculum acuminate, not hemi- 
spheric. 
B. SUBULIFERUM, sp.nov. Monoicum, laxe cespitosum, caule sub- 
simplici, foliis laxe dispositis patentibus elliptico-lanceolatis nervo ex- 
currente longe subulatis, marginibus a medio remote serratis, cellulis 
elongatis ad margines seriebus pluribus angustioribus limbum tenuem 
concolorem formantibus, theca in pedunculo elongato gracili suberecta 
pyriformi, peristomio Brachymenii. 
Hab. Island of St. Thomas, lat. 0, Mann. 
More nearly allied to Brachymenium lanceolatum, Hook. fil. et Wils, 
than to any yet known African or American species, and agreeing with it in 
size and general appearance; its leaves are, however, of a different form, 
having their widest part just above the middle, and thence gradually 
narrowing into the hair-like point. 
HYPNACEX, Mitten. 
Fasronis, Raddi. 
F. Persoonil, Schwegr. 
Hab. Island of St. Thomas, lat. 0, Mann. 
Growing on a species of Physcia similar or perhaps identical with P. 
speciosa. 
Hypnvum, Dill. 
(Brachythecium, Schimp.) 
H. vELLEREUM, sp.nov. Dioicum, czspitosum, caule procumbente 
ramoso, foliis sericeo-nitentibus teretiuscule imbricatis late ovatis con- 
cavis subulato-acuminatis, acumine semitorto, nervo tenui medio eva- 
nido, marginibus apicem versus minute serrulatis, cellulis elongatis 
basi ad angulos parvis concoloribus quadratis, pericheetialibus erectis 
ovato-lanceolatis, theca in pedunculo levi cylindracea erecta eequali, 
operculo conico acuminato, peristomio interno processibus angustis 
perforatis in membrana ad tertiam partem dentium longitudinis ex- 
serta, ciliis nullis. 
Hab. Cameroons Mountain, alt. 8000 feet, Mann. Abyssinia, near An- 
kober, Dr. Roler. 
Habit and size similar to that of the more robust states of H. salebro- 
sum, Hoffm., but leaves more turgid and faintly plicate. In the erect cap-
