var. ADPRESSA Dismier, Rev. Bryol. 34 : 68. (1897). 
Ph. adpressa Limpr., Laubm. 2 : 574, (1893), (desc. only). 
Stems about 5 cm., laxly coherent, scarcely radiculose, slender, 
simple, without subverticillate branches, leaves dimorphous, — some 
like the typical form, others distant, erect, strongly appressed broadly 
ovate, shortly acuminate. — {Essai, 399,) 
Range:— N. H., N. J., N. C. 
var. HETEROPHYLLA Dismier. 
Leaves of two forms: — the lower normal, the upper distant, ap- 
pressed, short, broader, with strongly chlorophyllose cells. 
Range: — Conn., Colo. 
A frequent species in America but greatly misunderstood. For 
certain identification the direction, form and structure of the leaves 
from the lower portion of a stem, not those of the innovations should 
be studied. The typical leaves are plane, with a thin costa. The 
lower cells are quadrate and the upper ones elongate rectangular. The 
species is found exclusively upon a silicious substratum. 
11. *PhilonOTIS FALLAX. Dismier. 
Dioicous; cushions yellowish to brownish green, interwoven with 
brownish radicles below. Stems upright, 3-6 cm. high, simple or 
with verticillate branches beneath the inflorescence. Leaves closely 
set, secund, narrowly oblong-lanceolate, falcate, slenderly acuminate, 
revolute to the middle, the margins dentate throughout with paired 
teeth; the costa slender, excurrent into a dentate hair; areolation of 
rectangular cells, papillae over the lower end. Male inflorencence 
discoid, surrounded by 6-8 patent bracts which are oval-lanceolate, 
concave, obtuse, denticulate, gradually narrowed from a concave base, 
with a thin costa which vanishes below the apex. Seta dark red, 
erect, flexuose, 5-7 cm. long. Capsule subglobose, with a small, 
short-conic, acute operculum. Teeth of peristome of medium 
length; processes of endostome deeply divided, cilia 2-3; spores large, 
brown, papillose.
