66 MR. W. MITTEN ON THE MOSSES OF 
Plants very minute, brownish, considerably smaller than B. brevipes. 
Leaves, when dry, appressed. In appearance, it resembles the smallest 
states of Pleuridium nitidum. 
3. LerrorRICHUM, Hampe. 
L. PRzALTUM (Mitten). Dioicum, dense cespitosum, robustum, caule 
elato subsimplici radiculis fuscis albidisve tomentoso, folis patulis 
siccitate incurvis recurvisve subcrispatis e basi ovali sensim ad apicem 
angustatis lanceolatis concavis nervo lato sed tenui partem lanceo- 
latam fere totam occupante, margine superne minute subserrulato, 
cellulis inferioribus oblongis ovoideis in rotundatas transeuntibus ala- 
ribus nullis, perichetialibus convolutis vaginatisque externis acumi- 
natis internis subito in acumen setaceum contractis, theca in pedun- 
culo elongato flavo cylindrica erecta, operculo subulato squilongo 
subrecto, peristomio parvo dentibus rubris dimidio superiore irregu- 
lari modo bi- trifidis annulo angusto, flore masculo parvo in caule gra- 
cillimo innovante e tomento in axillis foliorum plant: fertilis oriente. 
Hab. Magellan, in woods, Sandy Point, Lechler, 1022. 
In size and appearance not unlike Dicranum Drummondii, B. & S., 
but in the structure of its leaves closely allied to those species of Lepto- 
trichum in which the nerve occupies nearly the whole of the upper por- 
tion of the leaf. 
L. AUSTRALE (Mitten). Monoicum! caule elongato ramoso cespitoso, 
foliis erecto-patentibus elongato-ovalibus ellipticisve, cellulis elon- 
gatis areolatis, nervo in subulam setaceam apice parce denticulatam 
longe excurrente, perichetialibus elongatis convolutis apice abruptis 
nervo longo capillari excurrente, theca in pedunculo circiter semi- 
unciali pallide fusco ovali erecta fusca, flore masculo in ramo ex infe- 
riori parte caulis fertili egrediente terminali.—Lophiodon strictus, 
Hook. fil. et Wils. in Fl. Antarct. Crypt. p. 18. t. lix. f. 2. Didymodon 
longifolius, var. 3. penicillatus, eorund. l. c. p. 102. D. longifolius 
et Distichium capillaceum in Flora Nove Zelandize enumerati etiam 
huic speciei péttinent.

This most distinct moss has been wrongly described with dioicous 
inflorescence and striated leaves. In the specimens collected by Mr. 
Archer the stems are four inehes high, but the seta is not longer than in 
the shorter states of the plant. The capsules in all the specimens are 
too old to afford an idea of the perfect peristome; but in every other 
particular the structure is similar to that observable in the species of 
Leptotrichum, and not at all different from that of Weissia stricta, Hook. 
fil. et Wils. Flora Antarct. Crypt. p. 98, t. clii. f. 4, which is also refer- 
able to the same genus.
