Sagittata trifolia is
a perennial herb inhabiting shallow marshes or wetlands, extending
runners underground to make small corms at the ends. Leaves are
rooted; young plants' leaves are linear and in the water; generally,
however, they have long pedicles and are erect to get out of water.
Blades are sagittate, with bases split into two lobes, 7-15cm in
length; either of the two lobes is longer than the terminal ones and
tips sharply pointed. Flower stems grow to 20-80cm tall and set
three white flowers, 1.5-2cm across, in a whorl on each node; male
flowers come on the upper parts of the flower stalks, and females on
lower portions. Bloom time: August-October. |
