ORTHOTRICHUM -ANOMALUM, Hedw. Musc. Frond. II. 192, t. 37 
(1788). 
I have not seen the type of this species, but it would be de- 
sirable to know whether it has the teeth united in pairs, and 
whether the cilia are present, as Limpricht maintains O. savatile, 
Brid., on these characters. Braithwaite recognizes it only as O. 
anomalum, var. cylindricum, Sch., claiming that though Bridel’s 
name is the older it should be rejected because it was used to in- 
clude both O. anomalum and O. saxatile, forgetting that according, 
to the Paris code the enlargement or restriction of a species does 
not warrant a change of name. Venturi also considers it only a 
variety of O. anomalum, but calls it var. saxatile, 
We have found that No. 177 S. & L. Musci bor. Am., Ed. II., 
distributed as O. anomalum, agrees with the description of O. 
saxatile given by Limpricht, in having the teeth united in pairs, 
and eight cilia alternating with them; also the ridges of the cap- 
sule are only 8, with occasionally only a trace of the intermediate 
ones; the capsules are much exserted, cylindric, and longer than 
in O. anomalum. The leaves also have the walls of the lower cells 
thickened nodosely, and ‘the perichetial leaves are 4 mm. long. 
The specimens were collected at Niagara Falls, and we have not 
seen this species from any other locality, though it may be looked 
for among those labelled O. anomalum, and has probably been 
mistaken for that species. 
ORTHOTRICHUM CuPULATUM, Hoff. Deutsch. fl. ii. 26 (1796). 
O. strangulatum, P. Beauv. Prod. 81 (1805), fide Braithwaite. 
O. strangulatum, Schwaegr. Suppl. I. ii. 53, t. 34 (1816). 
I have not verified the synonymy of this species, though the 
types are probably at Geneva. O. strangulatum, Sull., of the 
Manual, however, is doubly debarred, as Venturi says it is the 
same as O. Braunit, Br. & Sch. As is well-known, O. cupulatum 
forms a marked group of closely allied forms or species, and 
hence has been variously treated by different authors. Braith- 
waite describes it as a polymorphous species with one variety, 
nudum (O. nudum, Dicks). Venturi recognizes O. nudum as & 
species, besides separating off O. urnigerum, Myrin, O. Sardagna- _
