This species was originally based upon material sent to Europe 
by Schweinitz, wrongly labeled C. foléolosa Muhl., which is very 
different. A sheet so named in his handwriting, now in the her- 
barium of the New York Botanical Garden, is however a Vitella, 
while another labeled by him C. xdifica is C. Schwetnitztt. 
4. Chara crinitiformis sp. nov. 
C. excelsa Allen, Bull. Torrey Club 9: 43. 2. 20, in part. 1882. 
Probably dioecious, but only maturing sporocarps have been seen : 
about ro cm. high, without calcareous incrustation ; stems 0.7 mm. 
in diameter, regularly singly corticated ; spine-cells frequent, usually 
in pairs, rigid, 1.2-1.6 mm. long, o. 16-0. 2 mm, — very acute 
and sometimes falcate at the apex: stipulodes form a single 
whorl at each node, twice as numerous as the leaves, sie to the 
spine-cells: leaves 10-12 in each whorl, 6-8 mm. long, entirely 
ably more mature 0.63 mm. long and 0.56 mm. wide, tage 
whorl crown-cells depressed-hemispheric, 0.1—-0.13 m igh, 
0.23-0 
Tee eee at Canadaigua Lake, New York, by T. F. Allen, 
August, 1881; inthe herbarium of the New York Botanical Garden. 
Distribution: Only known from type collection. 
Exsiccatae: C. excelsa Allen was distributed in nhs Char. Am. 
Exsicc. as ~o. 75, and small quantities of this were doubtless in- 
cluded, as the specimen here described was obtained from undistrib- 
uted material of that number. C. excelsa in all the more important 
characters belongs to the coz¢rarza group, but some portions of 
the description were based on C. crénttiformis.
