numerous, equidistant, 1' - 1 |' long, at right angles to tho stem ; leaves (tho
cauline twice as large as the ramuline) ercct-patent, rather distant or loosely

Our specimens are sterile, except those received from Mr. James since the
foregoing pages were printed. F . Novæ-Anglioe is a rather large species,
quite distinct from any before described, excepting F. biformis, the vernal state
of which it very closely resembles, and to which some sterile specimens collected
near New Haven, Connecticut, by Mr. Eaton, were erroneously referred
on page 54. The two species differ from each other as follows. In numerous
specimens of F . Novæ-Angliæ (those from Mr. James collected in August),
there is no indication of a second growth of differently shaped leaves, snch as
repeated observations during several years have shown to exist in F . biformis.
The first species has a pinnate, the second a fasciculate, ramification, with leaves
(in the venial state) one half larger ; their subflexuous areolæ have a length only
twice or thi'ice their width, and, being very obtuse at each end, are suggestive
of the name sphugnifolium, given to one of the forms of the species by Muller.
F . Novæ-Angliæ appears to be a more prolific species ; some of the specimens
exliibiting fructification in all stages of growth, from the minute flower-huds,
cuspidate by the exserted styles of their two archegonia, and lodged in the axils
of nearly every leaf on the upper portion of the plant, to the mature capsules
of the present and the decayed ones of the preceding season. In the otlier
species the capsules are very rare, and found only near the base of the stem :
besides their opérenla are longer. The peristome, usually supplying good disADDITIONS

tinctive marks in this genus, is (as with F. antipyrctica and F. squamosa) of no
account in distinguishing the two species under notice.
In all tho North American species of Fontinalis, and also in F. squamosa,
L. (which has not yet been satisfactorily ascertained to be a native of this
country), the leaves have auricles at their base, with an enlarged peUucid
areolation. The sporules in all are of about the same diameter, namely 555 of
a line.

Mr. James in Saco River, Crawford Notch, of the Wliite Mountains, New
Hampshire, and sterile specimens found in Rhode Island by Mr. Olney, indicate
for this species (heretofore deemed peculiarly southern) an unexpected
northern range.
