at the apex: seta yellowish, about 1.5 cm. long: capsule oblong-cylindric, 3 mm. long, smooth, 
with 2 rows of stomata near ihe base; peristome-teeth densely papillose, reddish-brown below, 
pale above, attached well below the rim and proj ecting above it about 150 u, irregularly divided, 
more or less perforate below, the apex often blunt; lid with a subulate beak about one half 
as long as the capsule: spores not quite smooth, 12-14 » in diameter. 
TYPE LocaLity: Cuba. 
DisTRIBUTION: Known only from the type locality. 
7. Holomitrium Maxoni R.S. Williams, Bull. Torrey 
Club 34: 572. 1908. 
Pseudautoicous: male plants minute, attached by radicles to the older ‘perichaetial buds, 
the outer antheridial leaves ovate-lanceolate, very acute, entire, 0.5-0.65 mm. long, faintly 
costate to ecostate, the inner much shorter, concave, brownish, enclosing apparently only 1 or 2 
well developed antheridia 0.2 mm. long and 2 or 3 paraphyses: fertile plants in rather dark- 
green tufts, with stems bearing few radicles up to 8 mm. high: leaves when dry incurved- 
imbricate with margins above rolled in, when moist spreading-recurved, oblong to linear, up 
to 2.5 mm. long and 0.4 mm. wide, at the apex mostly broadly rounded or somewhat truncate, 
with excurrent costa forming a stout apiculus, and a few coarse teeth on either side; costa 
a little above the base about 40 « wide, in cross-section near the middle mostly showing about 
2 guide-cells with 2 rather large cells on the upper side and no stereid-band, on the under side 
a stereid-band of somewhat variable size with the outer cells usually well differentiated; upper 
leaf-cells more or less hexagonal to oblong, about 12 » wide by 20-30 uw long, gradually becoming 
morerectangular in the middle of the leaf and toward the base longer and narrower next the costa, 
toward the margin paler and rectangular to square, the alar either forming a distinct brownish 
cluster or scarcely different from the cells just above: seta up to 18 mnt. long: capsule oblong- 
cylindric, erect, 3 mm. long, red at the slightly contracted mouth; peristome-teeth attached 
about one fourth their length below the mouth, red below, distinctly articulate, papillose on 
both sides and more or less divided along the median line either above or below or sometimes 
throughout; lid and calyptra not seen: spores nearly smooth, up to 12 » in diameter. 
TYPE Locality: Posesion de Starck, Zateras, Oriente, Cuba, 500 meters. 
DistRIBuTION: Known only from thé type locality. 
This species is evidently nearest to H. proliferum Mitt. of Brazil, but is a rather smaller plant 
with the lower leaf-cells narrower and not so lax as in that species.

VI. 3: 189. 1876. 
Eucamptodon piliferus Mitt. Jour. Linn. Soc. 12: 69. 1869. 
Pseudautoicous: male plants minute, growing on tomentum of the stem a little below 
the perichaetial buds, the antheridial leaves from lanceolate to broadly ovate, one third to 
nearly 1 mm. long, ecostate, with a very acute entire or nearly entire point; antheridia few, 
oblong, with few paraphyses: fertile plants in rather loose, glossy, yellowish-brown to dark- 
brown tufts, with robust stems up to 4cm. high and 0.28 mm. in diameter: stem-leaves 7—8 mm. 
long, rather crowded, inflated, loosely imbricate, ovate-lanceolate with involute entire borders, 
terminating in a pale, flexuous, smooth hair-point about 1 mm. long; costa weak, about 30 u 
wide below, indistinct above, in cross-section showing usually 2 large thick-walled cells on the 
upper side and a row of 5 or 6 small stereid-cells on the under side; alar cells short and broad, 
forming a distinct, brownish cluster, the other cells quite uniform throughout the leaf, elongate, 
with much thickened and pitted walls, the median cells 40-80 » long and about 12 uw wide; 
inner perichaetial leaves with a convolute base about 1 cm. long, gradually narrowed to a 
smooth point about one half as long: seta 15-18 mm. long: capsule oblong-cylindric, 3.5 mm. 
long, with stomata in 1 or 2 rows near the base; annulus none; peristome-teeth extending about 
300 pabove the mouth, entire, narrowly lanceolate, very slender and pale above, reddish below, 
papillose throughout: calyptra smooth, about 5 mm. long, split on one side far above the 
middle: spores rough, about 12 » in diameter.
