greeable odor of any found in this region. 
Var. delicatula, A. Br. 
Wenham, Aug. 3, 1876. 
Var. ——— 
Collected in Beaver pond, Beverly, July 17, 1879. Dr. Farlow in a 
letter of Nov. 16, 1879, says, of this plant: —‘‘I hesitate between 
€. fragilis and C. tenuispora. I think it a variety of the former, 
but uncomfortably near the latter. I have compared it with Euro- 
pean forms of C. tenuispora and the specimens are a good deal 
smaller than the European forms of that species. It is, however, 
more spiny than C. fragilis in which the spines are merely rudimen- 
tary in most cases. The stipular crown has the upper whorl more 
developed than in C. fragilis and, in this respect, the species also 
approaches C. tenuispora. In spite of the differences named,I 
should consider it a form of C. fragilis, judging by the general 
habit.” 
Chara sejuncta, A. Br. 
Among other specimens from Essex county, collected in 1879. 
Determined by Nordstedt through Dr. W. G. Farlow.
