Heteranthera limosa (Sw.) Wllld.
Warren County: T77N R22W Section 27 NE4 NE4 SW4 SE4
A corn field occurs on Red Rock Reservoir property, which is owned by the
United States Army Corps of Engineers (this portion is managed by the Iowa
DNR). It is approximately 1.7 miles southeast of Hartford. There were heavy
spring rains and so corn did not grow in low areas within the field. This site is
on the Southern Iowa Drift Plain.
2000+ Heteranthera limosa occur in an open, shallow, moist basin in the corn
field. Most plants have light purple/blue corollas, while a few have white
corollas. There are bare soil areas between plants. Heteranthera limosa is
associated with Ammannia coccinea. Heteranthera limosa has been
previously collected from these Iowa counties: Fremont (1888), Lyon (1954)
and Muscatine (1894).
