Rhopalanthus, (#. gen. Linps., Manip. Musc. Secundus, 1874, 
Pp. 390,) was wrongly printed “ Rhossalanthus”’ on p. 21, Vol. VI, of 
this Journal. It is very closely related to Scalia (/Jungermania) 
fookeri, Lyell. 
Anthoceros Donnellii, ~. s/.—Dioicus; frende plana subtenui 
levi indistinctissime late nervosa profunde laciniata subcrenata sub- 
tus copiosisssime tuberosa, involucro magno infundibuliformi, ore 
inciso, capsula sporis et elateribus fere ut in A, /evt. 
Banks of the Caloosahatchee River, Southwest Florida, Mar. 
1878; rare. 
Capsule and spores yellow ; the latter smooth, or nearly so. 
Fruit very rare. Has much the appearance of A. /evis ; but the 
divisions of the frond are narrower and more linear, and the invol- 
ucre is much expanded above, characters which readily distinguish it. 
The frond is somewhat channelled when dry, and often becomes 
somewhat fulvous in the herbarium. The tubers are always pres- 
ent, usually numerous, and are attached to the frond by a longish 
umbilicus. They are minute, nearly round, furnished with a few 
short radicles, at first white, but becoming brown. They are not to 
be confounded with the descending tuber-like apex of the midnerve, 
-which gives the specific name to A. tuberosus, Tayi.—a character 
which is not uncommon among the frondose Hepatice, and which 
sometimes occurs among the foliaceous ones.

Port Royal, S. Car., Apr., 1878, growing with A. /evis, var. major, 
A. punctatus, var. scariosus, and A. Ravenelit. It has also been sent 
to me during the past year from Mobile, Ala., by Dr. C. Mohr. 
Readily distinguished from the first of the above named species 
by its thicker subcristate frond, much shorter involucre not slightly 
expanded at the mouth when dry, shorter darker colored tortuous 
capsule, which ripens about one month later, smaller more papillose 
and opaque spores, and even more variable darker and broader 
elaters, &c. (Both the other species have black spores). 
Both A. /evis, L, and A. punctatus, L, are common in the South 
—the former especially so,—where they mature in March, and 
usually grow more luxuriantly than at the North (where they mature 
in Sept. and Oct.), and they frequently have the mouth of the in- 
volucre scarious, a phenomenon seldom witnessed at the North, 
and which appears to be produced by frosts while this organ is in a 
young stage of growth. A. /evis, var. major, Aust. (A. Caro- 
linianus, Mx ; A. Yaciniatus, SCHWEINITZ), is especially abundant on 
the Caloosa River. This and A. Donnellii were the only species 
found there. 4. punctatus, var. Eatoni, Ausv., was found on the ee
