Re: CULT: Black Spots in Pseudacorus

leaves. >>

The "black spots" John refers to are the "water marks" that William R. Dykes
noted distinguish the foliage of all true water irises. They are apparent when
the leaf is held against the light and look like very small dashes running
perpendicular to the veins.

John, I see no water marks in the foliage of I. ensata, but it does have a
midrib.

I. pseudacorus has no midrib, although it is thicker at the center in section,
but it does have watermarks.
