Among the 100 or more types of plant noted along a walk along the local
canal.

An orchid

I find the spotted/marsh orchids a confusing group, but my best guess on
this one is Dactylorhiza praetermissa. (The leaves of this plant were
unspotted.)

And a blue-flowered iris

Possibly Iris foetidissima, but I'm not sure that it's this and not Iris
spuria or Iris versicolor. (The books all refer to the fruits for
identification, which isn't helpful at this time of year.) I found then
same species elsewhere last year, but it disappeared before I could
check the fruits.

Any views
