width, or entirely wanting: antheridia 0.25-0.55 mm. in diameter ; 
sporocarps 0.75-1.1 mm. long, 0.45-0.6 mm. wide; odspores light- 
brown to black, 0.42-0.63 mm. long, 0.28-o0. fail mm. wide, with 
10-14 striae; whotl of crown-cells 0.1-0.2 mm. high, 0.21-0.28 
mm. wide at base, the individual cells oblong, pans 
Type locality : Europe. 
Distribution : Very widely distributed throughout North America, 
though with a more southern range than C. fragzlzs, and apparently 
not in the West Indies. Nearly cosmopolitan; the commonest of 
all species of Chara

The American representatives of this species seem to have larger 
antheridia and sporocarps than the European. The minimum 
dimensions for these organs given above were taken from Migula. 
16, Chara Morongii sp. nov. 
Monoecio 4-5 cm. high, yellowish- -green to dull-green, seed 
slightly rene stems 0.26-0.38 mm. in diameter, with ve 
irregular cortication, the primary cortical node- cells usually fornine 
secondary cells formed; the cortex usually appearing double, or 
more rarely triple or single ; ae -cells linear-lanceolate, lanceolate, 
or triangular, 0.1-0.35 mm. long, 0,05-0.08 mm. wide, mostly 
acute at the apex: stipulodes pee a single whorl at each node, 
twice as many as the leaves, 0.6-1 ss ong, 0.1-0.12 mm. wide, 
linear-lanceolate, acute at the apex : s 6 or 7 in each whorl, 2-4 
mm, long, contain ning 2-4 areas fe cee the terminal cell, en- 
tirely uncorticated, about o.15-0.25 mm. in diameter ; pee nearly 
equal, very similar to the stipulodes, 0.7-0.9 mm, long, 0.12-0.14 
mm. wide, acute or rarely obtuse at the apex, as bractoles nearly 
twice the length of the sporocarps : antheridia 0.23~0.26 in diameter ; 
sporocarps, probably immature, nearly spherical fee from the 
crown-cells, the largest 0.42 mm. long, 0.39 mm. wide; odspores 
0.32 mm. long, 0.33 pe wide, with 8 or 9 striae; whorl of crown- 
high, about 0.12 mm. wide at the base, the 
individual cells lanceolate- oblong, spreading
