Contributions to Japanese Characeae.—II. 
By T. F. Allen. 
11. Chara coronata Ziz., collected in Province Ise, differs in 
no essential point from the forms of Nos. 2 and 3. 
12. Nitella Japonica Allen, from a new locality in Province 
Ise, namely Yamagami ; distributed with No. 14, under the ex- 
siccatae number 9. 
13. Nitella pulchella sp. nov. 
Nitella polyarthrodactyla, monoica, gloeocarpa. 
Stems about 460 in diameter. Verticils consist of eight or 
nine leaves (with an occasional simple, undivided leaf, but not 
heterophyllus). Leaves about 150 in diam., thrice divided, 
primary segment much longer, (2680) ; first node bears 6—7 
secondary segments, 68 diam., 600 long ; second node bears 5 
tertiary segments, 34 in diam., 175 to 200 long ; occasionally 
one of these divisions is undivided like a simple terminal with 
three cells; the third node bears four to six (usually four) two- 
celled terminals, 25 diam., 170 to 240 long. The terminals are 
two (rarely 3) celled, the cells about equal in length ; the ter¬ 
minal cell is not mucroniform, but terminates, rather abruptly, 
in a sharp point (some collections more elongated and slender) ; 
other specimens, terminals very short, forma brachyteles. The 
fertile verticils are somewhat compact, and borne upon pedicels 
arising from the stem within the primary verticils ; the entire 
fertile verticil becomes a globular, gelatinous mass. The leaves 
of the fertile verticil are usually twice divided, the antheridia 
borne on the second node are about 225 in diam., and decidedly 
stipitate, the stipes 200 long and 54 in diam. The oogonia are 
borne on both nodes of the leaf, single ; usually on the terminal 
node, sessile, the cononula minute. 
The oospore, dark reddish, is 250 long, 200 broad, with 7—8 
prominent ridges, the surface is strongly reticulated, the reticulae 
5“ 12 in diameter. 
The relationship of this beautiful species is not clear; in some 
features it may be related to N. trichotoma A. Br., but it is clearly 
separated from it as well as from the subspecies Zeyheri and 
Lechleri. 
It may be considered remotely similar to N. gelatinosa A. Br.
