Re: aquatic spathiphyllum

From: "Ron Iles" roniles at eircom.net> on 2002.05.26 at 18:54:04(8883) Spathiphyllum cannifolium seems often reported as an emersed or intermittently submerged aquatic. Could its growth in full sunlight be made possible by the thick leathery leaves? Surely the thin leaves of Section Spathiphyllum species would not tolerate full sunlight? I have just re-read Deni Bown's magnificent Book & note the aquatic aroid genera. ANY supplementary observations would be hugely interesting & help me to find out how those aroids adapt to being fully emersed.. Below is a provisional list of Spathiphyllum species. Does anyone have ANY habitat & environmental observations please? SPATHIPHYLLUM SPECIES Section Massowia (K.

Goodwill to All Ron +More ----- Original Message ----- To: "Multiple recipients of list AROID-L" Sent: Friday, May 24, 2002 12:34 AM Subject: Re: aquatic spathiphyllum Dear Petra and Ron, Just to remember: Spathiphyllum gardneri (from Central Brazil) grows in river banks and most plants are usually flooded during the rainy season. I am not meaning a wet foot, but I am talking about completely submerged plants (sometimes only infructescences out of the water) for a month or two. In Amazonas state (Brazil), as well as in Venezuela, Spathiphyllum cannifolium grows in full sunlight in swamps, together with Urospatha and some Montrichardia. I have also collected Spathiphyllum humboldtii growing submerged up to the middle of its petioles close to French Guiana. The same situation in a potential new species of Spathiphyllum in Acre (I think Tom is describing this one) that was growing in a completely swampy area. I have never collected in Costa Rica or Colombia, but all Brazilian species of Spathiphyllum I have seem are helophytes or rheophytes. In fact, I have never seen a truly terrestrial Spathiphyllum in Brazil!
