0.47-0.5 mm. long, 0.28-0.35 mm. wide; leaflets at sterile nodes 
greatly reduced, 0.05-0.16 mm. long, or almost obsolete at the upper 
nodes, lanceolate to ovate, sometimes ventricose, those on the node 
between the uncorticated basal and the lowest of the corticated 
internodes 0.16-0.26 mm. long, ovate, mostly ventricose, usually 
spreading or even reflexed, as bracteoles the anterior 0.56-0.77 mm 
long : antheridia 0.28-0.37 n diameter; the doubfully mature 
sporocarps examined 0.84-0.9. I mm long, 56- wide; 
odspores 0.63-0 mm. long, 0.4-0 m as with 12-14 
m. wide, with 14 or 15 striae); whorl of crown-cells 
high, 0.16-0.21 mm. wide, the individual cells Paneer es 
Type locality: Main canal or Comanche Creek, southwestern 
Texas. 
Distribution: Texas to South Carolina and Florida, according to 
Braun and en. Several plants referred here by them, how- 
ever, belong to C. sejuncra, others are young stages of C. folzolosa. 
47. Chara Brittonii Allen, sp. nov. (Britton, Cat. Pl. N. J. 356. 
1889 ; without description) 
Monoecious, but the antheridia and odgonia usually though not 
aes at different leaf-nodes: possibly allied to C. sejuncta A. 
Br. ; cm 
mm. in diameter, different internodes varying greatly, entirely 
without cortex and spine-cells: stipulodes forming a ee whorl 
at each node, usually of nearly equal size, 0.9-1.2 mm. long, 0.04— 
0.06 mm. wide, or those in the upper row oo much longer, 
attaining a maximum length of 2 mm., sometimes also very short: 
leaves 7-9 in a whorl, 5-8 mm. long (the whorls overlapping), 0. 16— 
m. wide, containing 4 or § per Enee the node-cells small 
and apparently sometimes absent; lowest leaf- internode often oval, 
broader than the rest, resembling ‘that of many species of the gym- 
nopus group; leaflets at sterile nodes usually unequal, 0.3-1.2 mm. 
long, or like the bracteoles, the latter o.7-1.8 mm. long, 0.035-0.06 
mm. wide, far exceeding the sporocarps: antheridia 0.25-0.28 mm. 
in diameter ; mature ade se 0.85-0.93 mm. long, 0.6-0.65 mm. 
wide; odspores 0.6-0.65 mm. long, 0.4-0.47 mm. wide, with 1 
striae; crown-cells ovate, o. en ees rr mm. high, closely connivent. 
Type collected 2 miles southwest of Sparta, Sussex County, 
New Jersey, by N. L. Britton, September 16, 1887; in the her- 
barium of the New York Botanical Garden. 
Distribution: Only known from original collection.
