other two American species, L. julaceus and L. brachypus, in their 
more narrowly acuminate, longer-celled and nearly entire apices. 
On this continent L. sciuroides appears to be occasional through 
eastern Canada, while it has been reported from New York and Penn- 
sylvania and from all of the New England States but Rhode Island. 
It is a common European moss and is also known from Asia and 
Africa. 
Eropium Braxpowrn (Web. & Mohr) Broth. In a calcareous 
swamp, altitude 750 feet, Salisbury (A. W. Evans, 1911). The larger 
size, more ascending habit, and regularly pinnate branching give 
to this handsome moss a quite different appearance in the field from 
the common and closely related E. paludosum, the only other American 
representative of the genus. When dry the plants bear a superficial 
resemblance to Thuidium abietinum, but the different habitats of the 
two, together with the softer texture of the present species, preclude 
any possibility of confusion. Fruit is usually borne in more or less 
abundance, the spores maturing in May or June. According to 
Best ! the American distribution is as follows: Greenland; Labrador; 
Canada and British Columbia; southward to Idaho; Colorado; 
New York; Vermont. It has now been reported from all of the New 
England States but Rhode Island. Native to Europe and Asia. 
DREPANOCLADUS PSEUDOFLUITANS (San.) Warnst. At the margin 
of Twin Lakes, altitude 750 feet, Salisbury (G. E. N., 1911). De- 
termined by Warnstorf. This is one of those variable and intergrad- 
ing forms which group themselves so closely about D. subaduncus 
(L.) Warnst. (= D. aduncus of most authors). Whether or not it 
has justifiable claim to specific rank seems open to question. Renauld,? 
Mónkemeyer,? and Loeske,* after a critical study of numerous speci- 
mens both in the field and in herbaria, are of the opinion that this 
and similar forms, such as D. Kneiffii and D. gracilescens, represent 
merely varieties of D. subaduncus which are due largely to seasonal 
changes and ecological factors. Dixon, Grout, and Brotherus support 
this same view. But on the other hand equally careful students, 
prominent among whom are Limpricht and Warnstorf, regard many 
of these forms as distinct species. In its typical form D. pseudo-
