Radix repens, tomento fusco densissime obsita. Caules digitales
fere ad palmarem, simplices (vel rarius divisi. Labili.), inferne
nudi, nigri, nitidi. FoUa flavo-viridia, bifaria, disticha, verti-
calia, hixe imbricata, horizontalia, ovato-lanceolata, inæquila-
tera, subpellucida, tenuissime reticulata, serrulata, basi obsolete
uninèrvia. Stipulæ foliis triplo minores, orbiculatæ,
cauli appressae, denticulato-serrulatæ, enerves, apice mucro-
nulatæ. Perichætialia lanceolato-subulata, enervia. Perichætium
in axillis stipiilaruin, magnum, ovatum, fuscum, cor-
poribus pistilliformibus obsitum. Seta stipula duplo triplove
longior, curvata, basi incrassata. Capsula ovata, fusco-fer-
ruginea, minute reticulata, erecta, vel ob setæ curvaturam paulo
inclinata. Calyptra campanulata, inferne ventricosa, margine
integerrima, apice stylo terminata. Operculum e basi
conico acuminatum, acutissimum. Peristomium Hypni.
Scarcely any two authors are agreed as to the genus to which
this noble moss belongs. Those who have referred it to Leskea
have done so without understanding the true structure of the
peristome, which is most decidedly that of a Hypnum, in which
genus it would therefore be placed by those who do not regard
the calyptra as forming an essential generic character. To me
it appears rightly arranged with Hookeria, having all the marks
of that genus ; and so Bridel seems to think, for his Pterigophyl-
lum is precisely our Hookeria under another name.
After the fruitstalks have fallen, the bulbous perichætium remains
in the axil of the stipule, and may at first sight be mistaken
for the male flowers.
