while in F. ta^ifolius and F. osmundoides it is of less thickened cells and but 
one or two cells wide. F exiguus can be placed in this class though not 
always so closely and uniformly defined. It has a marginal row of ceils 
lighter and more pellucid as well as more nearly square or less irregular than 
the remaining leaf-cells. I had made a note of this when first finding the 
species several years ago, and have used it since as a help in distinguishing 
the two closely allied species. It is just as apparent in the example from the 
Musci Alleghanienses. In the drawing of the leaf F exigmts in Sullivant’s 
leones Muscorum, PI. 23, Fig. 9, this feature is not clearly brought out, and 
the margin does not differ essentially from the remaining cells of the leaf, only 
slightly more uniform perhaps. The squarish and more uniform size of the 
marginal row is more apparent in the plate accompanying the original descrip- 
tion in the Memoirs of the American Academy, n. ser. iii, Tab. 11, B Fig. 2, 
though as Sullivant viewed it, it was with “ foliis im margin atis,” as com- 
pared with the “ lamina limbata ” of F minutulus figured on the same plate. 
Leaves with a border row of pellucid cells of this character, whether called 
immarginate or marginate. are readily distinguished from those with the 
margin of F. m in utulus. As remarked above on the leaf of F. Bambergeri , 
where the border with the linear type of cells was absent, there was an 
appearance of the other type. 
Comparing the two in other respects the leaves of F. exiguus are more 
shortly and abruptly pointed, maintaining their width more fully to near the 
apex, making a shortly acuminate or acute leaf. Its capsule is commonly 
thicker in proportion to its length, 'the operculum with a shorter and stouter 
beak. In both the teeth are very papillose but in minutulus they are exceed- 
ingly long and slender, more so than in any considered in this paper, and so 
deeply cleft that one or both parts, though apt to be unequal, may be four 
times the length of the basal portion. In exiguus they are about twice the 
length, appearing less deeply divided though the basal part may be as broad 
as in minutulus. The trabeculae in F. minutulus are mainly horizontal but 
vary to oblique : or the projections may even take the spiral and somewhat 
thickened forms, the latter features quite exceptional as I have found them. 
In F. exiguus the spirally thickened form becomes more obvious, but as it is 
an inconstant character in both its value is not great in distinguishing them 
from each other, though on account of its quite uniform presence in bryoides , 
inconstans and incur vus, it is useful in separating the two from these. 
In conclusion I wish to acknowledge my indebtedness to Mrs. Agnes 
Chase, of Washington, D. C., for the drawings and for copies of descriptions, 
and to Mrs. Elizabeth G. Britton and Prof. W. G. Farlow for the gift or loan 
of specimens. Chicago, 111 .

CATHARINEA CRISPA IN MAINE. 
Alice L. Crockett. 
It is a pleasure to announce the discovery of a station for Catharinea 
crisfici James, in Maine, it not having been reported before from this State, 
nor so far northeasterly as this. It was found in fruit in Camden, Maine, 
44° N. lat. 69° W. long., in a pasture near the bank of a large brook, on 
knolls where six years ago a growth of alders had been cleared away. The 
altitude is about 200 feet. For its determination I am indebted to Mr. E. B. 
Chamberlain. Prof. J. Franklin Collins, in his list of New England plants, 
Rhodora 8: 13 1, 1906, gives only Massachusetts as definitely possessing it.
