Part 2, 1913] DICRANACEAE 93 
TYPE LocaLity: Naguala, Guatemala. 
DisTRIBuTION: Mexico and Guatemala. 
he only specimens in the herbarium of the New Vork Botanical Garden under this name 
were collected at Alta Verapaz (Turckheim 6653), and at Orizaba (Smith). ‘The fouuier are Histly 
not Dicranella; the few plants of Dicranella present have erect, appressed leaves, leaf-cells narrow 
with somewhat thickened walls even in the base of the perichaetial leaves, a broad annulus, peristome- 
teeth about 100 @ high, red and papillose, and spores rather coarsely papillose, up to 18 4 in diameter. 
he Mexican specimens are in fine condiiton, rather taller than those from Guatemala, but showing| 
no essential differences. \ 
26. Dicranella remotifolia Besch. Ann. Sci. Nat. VI. 3: 185. 1876. 
Plants in compact, deep tufts, brownish below, yellowish-green above, the slender, some- 
what branching stems up to 6 cm. high with rather distant leaves nearly uniform in size through- 
out, and spreading-crispate when dry, widely spreading and somewhat incurved when moist: 
leaves 2-2.5 mm. long, from a broad base gradually narrowed to a nearly linear, grooved, rather 
broad limb, with margins slightly revolute, the apex rounded-obtuse, somewhat cucullate and 
nearly or quite entire; costa stout, at base 80 » wide, about one fifth the width of the leaf-base, 
not quite percurrent: leaf-cells short-rectangular below, mostly one and one half to three times 
as long as wide, gradually smaller above, from nearly square to about twice as long as wide: 
fruit unknown. 
TYPE LocaLity: Guadeloupe. 
DISTRIBUTION: Known only from the type locality. 
Specimens in the Mitten collection from Guadeloupe (Marie 148) seem to consist entirely of 
male plants; they are about 1.5 cm. high with abundant, axillary, scattered flowers. 
27. Dicranella Miilleri Schimp.; Besch. Mém. Soc. Sci. Nat. 
Cherbourg 16: 163. 1872. 
Dioicous: plants laxly cespitose, brownish-yellow with minute stems: older stem-leaves 
erect-spreading, flexuous, distant, long-cuspidate from an ovate-lanceolate base, with margin 
very entire and everywhere revolute, the younger leaves exactly linear-lanceolate and flat; 
costa vanishing below the apex: male plant slender with the flower growing from the base of 
the stem: capsule, on a flexuous, reddish seta, oblong-ovate, erect or pendulous; lid with a short 
straight subula (according to Bescherelle). 
Type Locality: Cordoba, Vera Cruz. 
DISTRIBUTION: Known only from the type locality. : 
The specimens in the herbarium of the New York Botanical Garden are evidently part of the 
type collection; they are too immature to show any characters of the peristome; the filiform stems 
are 5-6 mm. high and; with the spreading leaves, scarcely 1 mm. across; the leaves at apex are 
mostly narrowly obtuse and crenate or denticulate and the costa vanishes 2 or 3 cells below the 
apex: leaf-cells rather pale, irregular and laxly rectangular throughout, the upper about 6 « by 25 pn, 
the lower up to 104% by 404.

3. CAMPYLOPODIUM (C. Miill.) Besch. Ann. Sci. Nat. 
V. 18: 189. 1873. 
Angstroemia § Campylopodium C. Miill. Syn. 1: 429, 1848. 
Small mosses growing on earth; American species dioicous. Stems erect, simple, with 
radicles at the base. Upper leaves from a more or less clasping base abruptly narrowed to a 
spreading-flexuous subula; leaf-cells mostly rectangular with scarcely thickened, not pitted 
walls and alar cells not differentiated. Seta stout, twisted and sinuous when dry, regularly 
recurved, sigmoid, or geniculate above the middle when moist. Capsule symmetric, smooth 
or sometimes appearing slightly ribbed, with an annulus and a conic, obliquely rostrate lid;
