Hookeria  Sullivantü, Müller. Plants forming bright glossy 
green patches; stems not matted nor tomentose, prostrate at 
base, 2-4 cm. long, innovations ascending, leaves intricate, 
flattened in one place, occasionally rooting at apex, 3-5mm. 
long, ovate-lanceolate, veinless, entire, bordered by a row of 
slightly larger, clearer cells, apex acute, areolation regularly 
rhomboidal, basal cells not enlarged, base contracted. Monce- 
cious, autoicous, the antheridia few in small leafy buds near 
the base of the pedicel. Perichætial bracts few, smaller than 
the leaves, more acuminate; pedicel stout, red brown, 
8-12 mm. long, twisted and curved ; capsule pendent, not con- 
tracted below the mouth when dry, 1-5 mm. long, lid 75 mm. 
conic, calyptra not seen.  Peristome double, teeth trabe 
culate. Along Nick’s Creek, at foot of Pine Glade Mt. In 
dark, damp spring ravine, on perpendicular face of wet rock, 
alt. 2,600 ft. Only two capsules found with old fruit and one 
operculum entangled among the leaves. Differs from P#rigo- 
phyllum lucens, Brid. in the acute leaves with longer narrower 
cells, capsules shorter and broader, not contracted below the 
mouth when dry, lid not rostrate, blunt. This species has 
been confounded with the above and was distributed by Sul- 
livant in his Musci Alleghanienses as 58 Hookeria lucens, 
and by Sull. & Lesq. Musci Bor. Am. Ed. II. 401 as Heokeria 
acutifolia, also recently as Péerigophyllum lucens by Dr. Barnes, 
collected by Prof. Underwood at Tallulah Falls, Ga. It has 
also been collected in Doe River Gorge, Tenn., by me 1885, 
and in Ohio and North Carolina by Sullivant and Lesquereux, 
Bolander’s Californian specimens and those with blunt leaves 
from Idaho, Oregon, Washington, Vancouver, are all Pterigo- 
Phyllum lucens. We have seen no specimens of the lattter from 
any locality east of the Rocky Mountains. (Plate 80.)
