recurvos atque costam prominentem velut biplicata ; circa 4 cm. 
longa, e basi latiore concava sensim in laminam lingulato-lanceolatam 
subfalcatam angustata, acuta vel subobtusa, integerrima; costa per-

optime seriatse, parietibus firmis, parum incrassatis, marginales ssepius

apicem ramorum et ramulorum plures, saepe binatae, brevissimae, 
2-3 mm. longae, laeves. Galyptra parcissime pilosa. Theca ovato- 
globosa, laevis vel siccitate leniter plicata, microstoma; operculum 
longe aciculatum; penstomium externum e dentibus breviusculis

Sogere, 2000 ft., epidendric, 515 a. 
A tine and distinct species, near perhaps to 31. Leratii Broth. & 
Par., and 31. longicaule C. M., but very marked in its straight, erect, 
rigid branches, the distinctly spiral arrangement of the crowded 
leaves, with their tips, when moist, often falcate and homomallous; 
and when dry closely incurved with the tips strongly enrolled, fre¬ 
quently showing their spiral arrangement rather distinctly ; and also 
in the extremely short seta. 
31. crinale Broth. & Geh. has among other differences the nerve 
longly excurrent and the upper cells elongate. 
Macromitrium ( Gometium ) papuanum Dixon, sp. n. 31. hispi- 
dalo Mitt, affine, paullo robustius, ramis erectis, perstrictis, 2 cm. 
vel paullo ultra longis, fusco-rufis, apice brevissime fastigiate ramu- 
losis. Polia erecto-patentia, haud patentia, sicca arete spiraliter 
contorta, quam ea 31. hispiduti paullo latiora, brevius, latius acumi¬ 
nata ; areolatio per totum folium fere homogenea, cellulae basilares 
vix elongatse ; omnes obscurse. Phyllautoicum. Fructu Cometii. 
Sogere, 2000 ft., epidendric, 515 h. With the last species. 
No species of the small and very distinct subgenus Cometium 
has hitherto been recorded from New Guinea. It is confined to the 
Malayan and Oceanic tropical regions, the nine or ten species being 
very closely related to one another; 31. orthostichum Nees may be 
considered the type of the group. Most of the species, including 
31. hispidulum Mitt., which in size and habit is the nearest to the 
present plant, have at least a few of the basal cells elongate and more 
or less pellucid (the drawing of the basal cells of 31. orthostichum in 
the Bry. jav. Tab. evii. fig. 11, is quite incorrect, and is probably 
drawn from a different species). This character, together with the 
erecto-patent, not horizontally spreading leaves, the straight erect 
branches, and the short seta, will separate it from any of the other 
species of the subgenus. 
Polytriciium juniperinum Willd. (Without number.) New, 
I believe, to New Guinea. Its distribution is almost universal in the 
colder and temperate regions of the world, rare in the tropics.
