Yellowish- ог lurid-green, densely caespitose or creeping 
among mosses: stems 6-15 mm. long, .12-.3 mm. thick, pros- 
trate or ascending, sparingly ramose, the Ф commonly continued 
through the development of an innovation from underneath the 
perianth, the median innovation sometimes accompanied by one of 
two lateral; root-hairs numerous, long, colorless : leaves close or 
approximate, obliquely inserted, patent or sometimes subvertica 
toward the stem-apex, usually firm in texture, rarely somewhat 
soft and flaccid, not decurrent, orbicular-ovate or subquadrate- 
elliptical, .36-г mm. х.35-.8 mm., the superior usually somewhat 
concave dorsally, the inferior more or less arcuate-convex, al 
emarginate-bilobed 1-1 their length, the acute or obtuse sinus 
commonly gibbous-recurved, the lobes obtuse, rarely subtr 
angular-acutate, those of the inferior leaves often slightly arc 
uate-recurved; marginal and superior leaf-cells 16-32 м (mostly 
20-25 и), trigones well developed (6-11 p), the cuticle with 
very obscure hyaline roughenings: underleaves small, lanceo- 
late-subulate and subentire or bifid and sometimes sparingly 
dentate at base: gemmae frequent, brown, subglobose-ellipsoidal, = 
uniseptate, 24—30 их 16-24 и, borne оп the apices of much mo" 
ed, larger-celled, 3-ranked leaves, these erect-imbricate ша тоге 
or less elongated terminal spike: dioicous: 4 bracts unidentate 
on dorsal margin ; antheridia paired, on very short stalks: % brac 
gradually a little larger than the leaves and sometimes with repand 
margins, otherwise similar: perianth ovoid to obovoid-oblons; 
1.5-2 mm. Х.0-1.2 mm., often apparently dorsal owing to ra 
early development of a strong hypogynous innovation, somewha 
laterally compressed in the upper half when young, the sm 
mouth minutely denticulate. 
In ditches, Mt. Dana, alt. about 3100 m. (Dr. H. N. Bolasi |
