(Br. & Sch.) Limpr., in the presence of cilia, and its habit of grow- 
ing on trees in shade. 
This is another of the cases so frequent in this genus, where 
the macroscopic differences are more distinct than the microscopic. 
We also have specimens collected at Raquette Lake, in the Adi- 
rondack Mountains N. Y.,which at first sight resemble W. curvifolia : 
more than W. Americana, but when compared with the normal 
form of the latter agree in the less papillose leaves, though having — 
the brown color, slender stems and short capsules like the former. — 
The leaves however are not as curved. Prof. Macoun has col- — 
lected specimens “on trees at Goulay’s Point, Lake Superior,” 
which also differ quite markedly from the dense black form with 
elongated capsules of our Eastern States. i 
In Sullivant’s herbarium there are also duplicates of these — 
specimens labelled « UJ. Hutchinsig,’ with the following note. — 
“Macoun’s No. 33 from Goulay’s Point, Aug. 5, 1869. Capsule — 
and pedicel not as figured in Br. Eu. Looks like U. Barclayi, 
Mitt.—See slide—_W. S. S.”

Orthotrichum coarctatum Beauv. Prod. 80 (180 5). 
Ulota Ludwigii Brid. Mant. 112 (1819). 
Lindberg and Braithwaite cite the above synonymy. — Lim- 
pricht doubts whether it is correct, cites O. coarctatum with a ? 
and says that the plant figured by Schwzegrichen (Suppl. I. ii. 26, 
t. 52) is a different species. He cites this plate under U. Bruchit. 
The original description reads as follows: 
Orth. coarctatum ; ap 
foliis linearibus, siccitate crispis, costa integra notatis; py! 
ibus erectis, pyriformibus ; orificio striato, coarctato; calyptra pal 
lida, hirta. 
J’ai rapporté cette espéce de PAmérique septentrionale. Elle a quelque rapporte- 
avec P Orth. crispum ; mais elle en difére par la forme de l’urne et son orifice 5 
et rétréci, i 
It will be noted that the leaves are described as crisped, am 
that the plants are compared to O. crispum; but, on the other 
hand, the description of the capsules ageees with that of U. Lud- 
wigit.
