Tetraplodon australis Sulliv. & Lesq. Some specimens of this species 
sent me from Thomasville, Ga., by Mrs. A. P. Taylor, were so unlike any of 
the descriptions, that I at first thought they must belong to a different 
species and perhaps a different genus. The leaves were entire and as long, 
and slenderly acuminate as in T. angustatus ; the columella was distinctly 
exserted, the teeth reflexed, and the hypophysis so reduced as to make only 
a moderate sized neck. An examination of Sullivant & Lesq. Musci Boreali- 
Americani, Edition i, No. 15 1, in the Columbia University Herbarium revealed 
at least one capsule with an exserted columella and at least one capsule in 
which the hypophysis is as reduced as in the Thomasville specimens. No. 227 of 
the Second Edition has many exserted columellae and many capsules with 
small hypophyses, but has leaves as strongly serrate as those figured in the 
leones. An examination of the other specimens in the combined collections 
of Columbia University and the New York Botanical Gardens showed that 
the small hypophysis and exserted columella are common variations found in- 
termingled with plants like those figured by Sullivant. The presence of 
nearly entire leaves in rare cases is noted in the Manual. The teeth seem to 
be normally reflexed in perfectly ripened capsules. These observations indi- 
cate that the speices is an exceedingly variable one, intermediate between 
Tetraplodon and Tayloria, and suggest that it may perhaps be better referred 
to the latter. More exhaustive knowledge of the two genera than I at 
present possess is needed to decide this. 
Anacamptodon splachnoides (Frol.) Brid. Specimens of Anacamptodon 
sent by Mrs. A. P. Taylor, from Thomasville, Ga., have the costa somewhat 
thinner and almost percurrent ; the seta longer and the capsule slightly larger 
than in the ordinary run of specimens : the operculum is scarcely more than 
conic in most of the specimens. Dr. Best suggests that it may be a ;trans- 
ition form between A. splachnoides and A . Cubensis Sulliv. which is based 
on Wright’s No. 66. A. Cubensis is said to be closely related to A. splach- 
noides , but smaller with a percurrent costa and a conic-acute operculum. 
(See Jour. Linn. Soc. 12:540). I should not be surprised to find that the 
Georgia moss is identical with A. Cubensis. Until this can be definitely 
settled, I propose that this form be known as Anacamptodon splachnoides 
Tylorsae. 
Brachythecium Noveboracense Grout. A continued study of this 
species in the field has shown that this species is a derivative of B. rivulare, 
and is common in Long Island swamps. The gametophyte characters given 
in the original description (Bryologist 3: 36. 1900) are generally characteristic 
of the species but the capsules figured there were abnormally straight, and 
the seta is less papillose than in most specimens. 
Burnettia fabrofolia n. sp. 
Closely resembling B. subcapillata, but with branch leaves broadly 
lanceolate to ovate-lanceolate, much more gradually narrowed to a longer 
and more slender acumination: median leaf cells about 1/5 larger, 60-80 x Sju, 
quadrate alar cells fewer and larger, about 16 ju wide; capsule less gibbous 
and less plainly narrowed at the mouth.
