Waterhyacinth (
Eichhornia crassipes
(Mart.) Solms), is a serious
problem in the Sacramento/San Joaquin Delta, California.
There is little published information on its phenology or
seasonal growth in this system. Waterhyacinths were sampled
at 2 to 3 week intervals from November, 1995 to July, 1997
and the following measurements were made on individual
plants: dry weight, height, number of living leaves, number of
dead leaves, and the width of the largest lamina. (PDF has 4 pages.
