17. Notes on Vallisneria. 
By L. A. Kenoyver, Px.D., Allahabad School of Agriculture. 
While collecting ee: plants at Allahabad two years 
ago, the author’s attention was drawn to a miniature Vallis- 
neria which grows near the age of several of our lakes. It 
has leaves 2 to 4 inches long, a pistillate scape 6 to 12 inches 
long, and grows at a depth of less than a foot. After flower- 
ing the capsule very rapidly elongates, ultimately becoming 
about 60 by 2 mm. There also commonly occurs a much 
larger form in water 4 to 8 feet in depth. This has leaves 2 to 
4 feet long, a pistillate blossom twice as thick and somewhat 
longer than that of the former, a much longer and thicker 
pistillate scape and a capsule about 40x 6mm. In all other 
characters they are similar. Vallisneria spiralis, L., is des- 
cribed as a cosmopolitan and very variable species. One 
would think these two plants represent the extreme size forms 
mediate forms in the same waters. and that whereas some lakes 
contain both forms, others contain only the one or the other. 
In one of the lakes near Gwalior the larger of the above 
forms was seen. But in the flowing water of the Morar River 
are two other forms. So far as size of the plant is concerned, 
both these forms are intermediate to the first described. One

while the basal portion remained alive to mature its seeds. 
The other form has pods thicker. slightly curved, and some- 
what enlarged toward the t 
Material of the indian "Vallionarta forms has been sent to 
Dr. Robert B. Wylie of the Iowa State University, U.S.A. In 
a recent paper (The Pollination of Vallisneria spiralis. The 
Botanical Gazette 63:2, February 1917) he points out Te 
differences from either. Those differences may be summed up 
in the accompanying table.
