HYPNUM BIFARIUM.
Hypnum caule erecto subpinnatim ramoso, foliis distantibus
bifariis lanceolatis marginatis serratis, nervo ad
apicem attingente, capsula ovata borlzontali, operculo
rostrato curvato. ( T a b . LVII.)
H ab . In sinu Dusky Bay dicto, apud Novam Zeelandiam.
f l . Menzies, 1791.
Radix e fibvis numerosis ferrugineo-fuscis dense tomentosis.
Caulis pollicaris, erectus, flexuosus, pleiùmque pinnatim ra-
inosus, ramis patentibus. Folia flavo-viridia, bifaria, disticha,
erecto-patula, distantia, lanceolata, paululum concava, marginata,
serrata, basi in caulem decurrentia, nervo ad summum
apicem attingente instructa. Ferichætialia acuminata, integerrima,
immarginata, nervosa, fusco-viridia. Seta sesquiuncialis
et ultra, rubra, flexuosa, prope medium caulis inserta.
Capsula ovata, horizontaliter inclinata, subapophysata. Operculum
hemisphæricum, rostratum, rostro curvato. Peristomium
ut in plurimis Hypnis.
This very elegant species of Hypnum ranks naturally near
Leskea Novcs Hollandice, and Hypnum distichum of Swartz, in
Schrad. Diar. Bot. v. iv. i. 3. Both these species, however,
have simple stems, and their fruitstalks inserted at the very base
of the stems. H . lifarium has the leaves decidedly thickened at
the margin, and the back of the nerve, upward, under a high
magnifying power, is also slightly toothed.
