short involucre, for the large black~papillose spores, and for the very 
short elaters, 
There are mixed with and adhering more or less to the spores 
and elaters, a great many short geniculate slender pale jagged fila- 
ments. These are, doubtless, of the same nature as the filaments 
which adhere to the columella in some species (e. g., A. Ravenelii). 
Probably they are the remains of the effete cellules matricales.

Remarkable for the large black globular tuberculated granules 
just beneath the surface of the frond, which give it a strikingly 
warted appearance, for the large minutely papillose spores, and for 
the short-jointed flat elaters. About the size of small forms of A. 
punctatus; from which it is readily distinguished by the different 
texture of both the frond and involucre, as well as by the much 
larger neither angled nor muriculate spores, and by the jointed 
elaters. The joints of the elaters are nearly or quite as broad as 
long, very flat, roundish (variable in shape and size) and placed 
end to end or often here and there two of themside by side. The 
fronds are (in my specimen) cxspitose and mostly erect. The gran- 
ules under the epidermis are easily separated from the frond by 
maceration. (A. glandulesus,L & Lg., has somewhat similar granules 
’ in the upper surface of the frond, but they are much smaller, not 
so exactly globose, and of a pale color.) 
* 13. Anthoceros Joorii, ». sp. ?—Size of the plant about as in 
the three last described species; in texture intermediate between 
the first two of them. Spores and elaters much as in A. Leseurit, 
but there are no jagged filaments mixed with them as in that species, 
nor is the columella fibrillose as in A. Ravenelii., However, 1 am 
inclined to believe it will prove to be a more mature state of the 
last-named species.
