concave, not carinate, long acuminate-tubulose, rigid, erect- 
spreading, 3-4 mm. long, 1-14 mm. broad, in three very dis- 
tinct ranks. Cells of the areolation long linear, rather firm, 
those of the angles more or less enlarged and generally 
brownish or ferruginous. Perichztial leaves rounded-obtuse 
and lacerate at the apex. Capsule entirely concealed in the 
perichetium, 2 mm. long, 4-? mm. broad; lid unknown; 
teeth about 1 mm. long, narrow, linear-acuminate, slightly 
papillose, often connected in pairs at the apex, with 20-25 
lamella on the inside, not perforated on the dorsal line; lat- 
tice-cone of the inner peristome strongly papillose, the lower 
transverse bars appendiculate. 
Tegon: on old logs in swamps (Zh. Howell). 
Already in 1881 Mr. Lesquereux communicated to us 
this plant ; but the specimen was poor and sterile. Recentl 
we have received from Mr. Th. Howell good fertile speci- 
mens of this very fine moss, which is at first sight distin- 
guished from all congeners by its strikingly rigid aspect, 
the arcuate branches and the dimorphous leaves, the branch- 
leaves being narrow and tubulose in the upper part. 
Fontinalis flaccida.— Plant very soft, yellowish. Stems slen- 
der, naked below, 25-35 cm. long; branches subpinnately 
ramulose ; branchlets spreading, slender, distant. Leaves 
Soft, distant, open, but convolute-imbricate at the top of the 
tamuli, elongated, narrowly lanceolate, plane or nearly so, 
obtuse or truncate, and slightly denticulate at the apex; 5-7
