Identify these two plants

 Please take a look and tell me what these are. Located at a lake outside
Portland Oregon. I believe one is wapato... but which? And what is the
other? They are growing in the same area, are similar in size and have
similar flowers.

Thanks in advance.

 You definitely have two species of Sagittaria (= wapato = water potato)
there.

Cannot determine exactly which species because the diagnostic floral
characters are not visible in the pictures.

Both probably have tuberous rootstocks.

Look them up in a flora of the Pacific Northwest.

 Taking a wild guess, the broad leafed plants is probably Sagittaria
latifolia and the narrow leafed one is probably Sagittaria cuneata. Both are
called "wapato"!!!

 Could be latifolia and cuneata, but the purple color on the narrow leaved
variety throws me. Here are links to pictures of the flowers from both
kinds.
These are from the type I think is S. latifolia:

This is the flower from the purple striped one, and you see how purple the
stem is:

Thanks for any opinions.
