It is characterized by having a peculiar brownish green color, the 
tips of branches lighter; very short turgid branches which are 
largest in the middle and at the largest part bear leaves as large as 
the stem leaves; capsule and seta much shorter and teeth more 
perforate than ‘is typical. E. Transylvanicus Demeter and E£. 
minutipes Kindb. are said by Limpricht, l. c. to be identical, and 
only slightly divergent forms of Æ. cladorrhizans. I have ‘been 
unable to see specimens of either.

Gametophyte in wide glossy yellowish-green mats; stems 
about 5 cm. long, more or less complanate-foliate ; branches nearly 
terete, 5-10 mm. long, often giving off short secondary branches ; 
branch leaves imbricate-appressed, oblong-elliptical to ovate, 
about 1.2 by 0.7 mm., short-apiculate, entire or slightly denticulate 
above ; costa short and double, median cells linear; quadrate alar 
cells numerous; stem leaves ovate, larger, with rather broader. 
cells; monoicous; male branches abundant, short-stipitate ; an- 
theridia comparatively. few, large, oblong; perigonial leaves obo- 
vate, apiculate, entire, bordered with a row of narrow cells, ecos- 
tate; paraphyses large: perichaetium about 2.5 mm. long, loosely 
sheathing; the inner leaves oblong-acuminate, serrulate at 
middle. Sporophyte 1.3—1.6 cm. high; capsule reddish brown, 
cylindric, 3-3.5 mm. long, 5-6: 1; operculum conic-rostrate ; an- 
nulus of two to three rows of small cells, obscured by base of teeth ; 
teeth of peristome subulate, short, 0.3 mm. long, very deeply in- 
serted, about 1 below the mouth of capsule, dark reddish brown be- 
low, much lighter above, bordered by a lighter margin, with a very 
distinct median line throughout the entire length ; articulations
