of Quito and Weddell’s from Peru, we have thought it best to 
enumerate them under this species. 
POLYTRICHUM ANGUSTICAULE C.M., n. sp. Near Yungas, 4000 ft., 
1885 (3155). 
Plants large, 8-ro cm. high; stems simple, 2-4 cm. high; leaves 
6-8 mm. long, the clasping base oblong, brown or slightly scari- 
Ous on the margins, tapering into a slightly longer apex, with in- 
curved entire margins; vein rough on back, with two or three 
rows of sharp teeth, excurrent into a smooth or only slightly rough- 
ened awn; lamellae covering almost all of the blade, of 6-7 rows 
of cells, the last row elongated, conical and smooth. Dioecious ; 
male plants proliferous ; perichetial leaves with a long smooth 
Point; seta 6-8 cm. long, stout, glossy, curved at apex; capsules 
large, 5 mm. long, cubic, with a short wrinkled apophysis; lid 
dark red, beak long; teeth white, 64. 
Closely allied to P. aristifiorum Mitt., and compared with speci- 
mens sent us by Wm. Mitten, collected in Venezuela by Funk and 
Schlim, no, 472. Differs in the longer, scarcely roughened awn of 
the leaves, which are more closely appressed when dry, and in the 
larger capsules. 
PLEUROCARPI. 
All the specimens of the pleurocarpous mosses as well as the 
acrocarpous ones were carefully studied and separated before du- 
Plicates were sent to Dr. Miiller, yet in two cases in the genus 
ffookeria, there was evidently a mixture of species growing to- 
gether, which in one instance seems to have misled Dr. Miiller. 
Hooxeria Baxert E. G. Britton, n. sp. Near Yungas, 4000 ft. 
1885 (3163). 
Plants yellowish-green, large and coarse; stems 2~3 cm. long; 
branches 1 cm., leaves curled and crisped when dry, more or less 
undulate with long subulate tips 2 mm. long, veins prominent 
when dry, ending just inside the margin, which is entire below, - 
Serrulate along the tapering apex and bordered by 3 rows of nar- 
Tow, elongated cells; those of the blade very large and clear, not 
Papillose. Pedicel 20-25 mm. long, bright, glossy brown; cap- 
‘Sules ovoid, 2 mm., brown, walls thick; lid conic-rostrate ; teeth : 
long, slender, brown and incurved in pairs, and papillose; endo- 
stome yellow, erect, carinate segments closed. 
Compared with H. marginata to which it is related, but differs 
in the lighter green leaves, broader and less acuminate, the cells — 
more lax and hyaline. — :
