as high as the teeth, finely papillose and with sometimes 
broad, often rounded appendages above; no intermediate 
cilia; spores smooth, up to 16 p. 
Apolo, 1500 meters elevation on sandy soil, Feb. 19, 1902 
(1882). This species has a superficial resemblance to small 
forms of Alntobryum albrcans. 
Brachymenium dimorphum sp. nov. 
Dioicous; male plants very small, 3 or 4 mm. high, with 
solitary, terminal flowers and radicles at base attaching it to 
fertile plant; antheridial leaves ovate, acute, serrulate above 
and costa scarcely percurrent, with marginal cells scarcely 
forming a distinct border: fertile plants with stems tomentose 
and leafless below, up to 2.5 cm. high, with leaves when dr 
more or less appressed and twisted about stems; leaves ovate 
or ovate-lanceolate to elongate-oblong, acute, the upper and 
perichaetial, 2 mm. long, serrulate above, with stout costa 
excurrent into a short point; margins flat and bordered with 
one or two rows of greatly elongated, narrow, thick-walled, 
golden-brown cells; median leaf-cells elongate-hexagonal, 
about 20 x 4oys below cells more or less rectangular and 
nearly square at basal angles; cell ae excepting border, 
thin but somewhat pitted throughout: ee erect, ovate- 
cylindrical to nearly cylindrical, “with lid up to 4.5 mm 
on a seta up to 2 cm. high; lid narrowly coca its height 
about twice basal diameter ; annulus large; peristome of 
slender, red, papillose teeth about o.7 mm. long and 25 # wide 
at base with 12 or 14 lamellae on inner face and median line 
indistinct; the inner, a papillose red membrane extending 
above the mouth about one fifth the height of teeth, with an 
irregular, slightly incised margin; smooth, pale spores up to 
New Brazil, upper Mapiri region, 1500 meters elevation, 
on trees, June 15, 1902 (1803). In habit this species is like 
B. Regnelli: but leaf margin different.
