Leaves of the lower sterile verticils often simple, somewhat ab- 
ruptly pointed; of the upper, once or even twice divided. First 
segment of the leaves 680 in diam., second 500, the terminals 320 
to 340. The first segment nine-tenths the entire length of the 
leaf, the second segments usually terminal in sterile leaves, three to 
Six, quite short (one tenth the length of the first segment). 
Fertile verticils ave usually somewhat condensed in small heads, 
quite similar to N. stellaris A. The leaves are usually twice 
divided, the terminal segments, three to four in number, are quite 
unequal, generally with one, scarcely longer than broad, others 
SIX Or more times as long, seeming to be somewhat inflated 
and not always very acuminate, often somewhat apwulate. An- 
theridia 240 in diam. Odgonia, one or two at a node, with 
Oospores 295 to 306 long and 272 broad, with seven prominent 
ridges. Membrane of the spore reddish, gwite smooth. (Plate 286.) 
This interesting species is similar to the American swb-glomerata 
in its general aspect, though apparently much smaller; its ‘ capi- 
tulae” are much smaller and consist of small fertile verticils aris- 
ing within the sterile verticils. It differs from swdglomerata, also, 
by its more inflated terminals, which are usually quite short and 
unequal, as well as by the character of the odspore. From 
Bellangeri (acumunata var. Bellangeri A. Br.) it is clearly distinct, 
though approaching that form in which the short terminal leaflets 
are described by Braun as “ ventricosis, longe et acutissime acu- 
Minatis ;” finally from all others of the acuminatae group except 
the preceding s¢e//aris A. by the smooth membrane of the 06- 
spore. From J. sze/lans it differs by its more diffuse habit, its 
smaller stems and much larger and differently shaped terminals ; 
its larger antheridia and odgonia. From J. subspicata A. it dif- 
fers especially in its much smaller capitulae, the shape of terminal 
segments of the leaves and by its larger odspores. 
This plant was collected in Japan in 1895. 
The “acuminatae” group as above amplified by these new 
Species, may be classified as follows: 
Monarthrodactylae, furcatae, homoeophyllae, gymnocarpae, 
monoicae, acuminatae.
