ELEOCHARIS, R.Br. Spike-Rush. 
1092. E. capitata, R.Br. 
“Found in a single locality in a slough south of Whiting, Ind., Au-. 
gust 29th, 1881, and described in Botanical Gazette, VII, 3 (1882), 
as E. dispar. 
Elsewhere in the United States, E. capitata ranges, as far as re- 
ported, throughout the Gulf States from Florida to Texas, New 
Mexico, Oregon and the borders of Colorado Desert. It is found 
in Mexico and several of the West India islands. As far as I have 
ever seen in examining many of the plants at Whiting, they 
have but two stamens, though the number of stamens in species 
of Eleocharis is not constant, and is not regarded as reliable in 
characterization. It is an annual plant in our district, without 
rhizomes to perpetuate it. Having observed it for several years, 
I find that the seeds germinate in the latter part of June, in the 
water or mud. 
On looking for the plant the present season, (1889) the stems were 
about ^ inch high, the first of July, thickly covering the ground 
in spots. On examining the plants about the middle of October, all 
were dead, root and stem, although dried stalks were plentiful. 
Its season, therefore, is from three and one-half to four months,”
