Leptobryum pyriforme in its sterile state is apparently common in green- 
houses, but is so different in appearance from the fruiting form as to be recog- 
nized only occasionally. Probably it will not be difficult to find the form bear- 
ing brood bodies in other localities. A photograph of the Miami plants (X io) 
accompanies these notes.

FONTINALIS UMBACHII CARDOT 
E. J. Hill 
This water moss was described by Cardot from material found in the Des 
Plaines River at Romeo, Illinois, by Prof. L. M. Umbach. It was published, 
together with a plate, in the Minnesota Botanical Studies under the caption 
“Two new species of Fontinalis ,” the other being F. llolzingeri Card. I have 
never seen any mention of it in the Bryologist. The name does not appear in the 
Ten-Year Index by Mrs. Smith, nor do I find it in any volume not covered by 
it. Having collected it in the type locality and since then in two more streams 
in the neighborhood, some account may be acceptable to bryologists, as it is 
said by M. Cardot to occur in localities farther north in Minnesota and Wis- 
consin, and is, therefore, likely to be met with by others. Since the Minnesota 
Botanical Studies may not be very accessible to all readers of the Bryologist, 
I will include a translation of the Latin description of Cardot. 
“Fontinalis Umbachii Cardot.* Dry plant rather rigid, dark below, lurid- 
green above. Stem denuded at base, 7-15 cm. long, irregularly pinnate, the 
branches remote, spreading or erect-spreading, the point cuspidate. Leaves 
somewhat rigid, erect-spreading, convolute-imbricate at the apex of the stem 
and branches, dimorphous; cauline large, oblong-lanceolate, gradually broadly 
and obtusely acuminate, entire, about 5 mm. long, 1. 5-1. 75 broad at base; branch 
leaves much smaller, somewhat close, a little curved and sub-homomallous at 
the apex of the branches, narrowly lanceolate, canaliculate as usual by inflexed 
margins, gradually obtusish-acuminate, entire, 3-4 mm. long, 0.5-.075 wide at 
base. Alar cells subquadrate or subhexagonal, slightly dilated, the others linear, 
subflexuose, moderately chlorophyllose, the thickish walls quite firm, the upper 
shorter. Fruiting part unknown.” 
The author adds that he recognized in his herbarium some stems of the same 
species collected in 1895 by Prof. Conway MacMillan in northern Minnesota 
near the International Boundary. He also compares it with F. Missourica 
Card., which it closely approaches, but from which “it is easily distinguished by 
its shorter and rather rigid stems, its more shortly acuminate stem leaves, which 
are narrower at base and entire at apex.” 
Though I received from Prof. Umbach a specimen from his type collection, 
the type locality was not visited till June, 1906. It is at the head of an island 
(Isle la Cache of the early French voyageurs), which, at this point, divides the 
Des Plaines, the western channel of which usually becomes almost dry in sum- 
mer. The shallow water of the river flows over a limestone bed with pieces of 
loosened rock or boulders from the bordering drift scattered over it. To these
