slender and flexuose. They are what we have been calling OQ. 
Lexanum, without any inner cilia. Specimens collected by J. B. 
Leiberg, No. 134, sent to Dr. Venturi, were named by him 0. 
rupestre. They seem to be the form figured in the Bryologia 
Europea 7.277 as var. y. U. Sehimeyeri Hornsch. None of the 
European specimens in the Jaeger herbarium are as slender or 
branching, all are more rigid, and Iam inclined to think they show 
the same divergence from O. rupestre that O. papillosum does from 
O. Lyellit. 
It will be remembered that in the Icones, Sullivant figured O. 
Lexanum without cilia, but in the description he says they are 
Present, but more or less rudimentary. It will also be remem- 
bered that the localities cited in the mosses of the United States 
are Texas, Wright; Santa Fe, New Mexico, Fendler, and that 
later in the Icones he added California, Bolander. The specimens 
distributed as No. 187 of S. & L. Musci, Bor. Am. Ed. 2, are from 
Texas. They are rather unsatisfactory, and I find them just as im- 
Perfect both in Prof. Eaton’s set and in Sullivant’s herbarium at 
Cambridge, but the description calls for tall lax specimens like 
these of Miss Mann’s, 
II. Group oF OrTHOTRICHUM SPECIOSUM. 
This group includes those species of the genus which have 
long, cylindric, exserted capsules with very faint ridges or entirely 
Smooth. The teeth in pairs, reflexed or recurved when dry, and 
the Cilia 8. erect. Six species and § varieties are here included: 
O. speciosum, O, elegans, O. Killiasii, O. levigatum, O. Kingianum 
and O. rhabdophorum. O. Rauei and O. Hainesie have been de- 
scribed by Austin, but reduced by subsequent authors. 
8. ORTHOTRICHUM SPECIOSUM Nees. 
ie This Species occurs in the Eastern States from New Jersey to 
e 
w Hampshire, is very common in Ontario, Quebec and the 
tern Canadian provinces, extending west to Vancouver Island.
