Re: Philo's and wet feet

From: "Eduardo Goncalves" edggon at hotmail.com> on 2002.05.24 at 04:08:22(8864) Hi, Yes, many Philos are real aquatic plants. In subgenus Meconostigma (self heading philos), many species are exclusively aquatic emergents (P. uliginosum, P. brasiliense, P. tweedianum, P. dardanianum and a new species I am describing from Espirito Santo state). However, some hemiepiphytes are also known to occur occasionally in standing water like P. undulatum, P. lundii, P. goeldii and P. bipinnatifidum. In the other subgenera, aquatic species are not proportionally so common, but they do occur. Philodendron muricatum is quite common in flooded portions of the Amazonas river, as well as P. brevispathum is common in Mauritia swamps. There is a small species, P. flumineum, that is the only species of Philodendron known to be a true rheophyte, i.e., growing in rocks along fast flowing rivers in Central Brazil. An extreme exemple of the weird habitats used by Philos is the occurrence of P. martianum and P. crassinervium in rocks, very close to the sea water. They do not send roots to the water (surely), but usually their leaves have whitish spots cause by evaporated drops of salty water... Philos are weird plants! +More Very best wishes, Eduardo. >From: "Sheralee & Iain McGregor" >Reply-To: aroid-l@mobot.org >To: Multiple recipients of list AROID-L >Subject: Philo's and wet feet >Date: Thu, 23 May 2002 10:47:21 -0500 (CDT) > >I have seen situations when philos(climbers&self headers)have grown roots >into nearby ponds and aquariums and change from seeking roots into feeding >roots . >I've grown philos with the pot standing in water with good results. >Finaly I see philos growing semi aquatic in Eliovson's book >on the gardens of Burle-marx. >The question is can some philos grow with the complete root zone >underwater? > > > >_________________________________________________________________ >Get your FREE download of MSN Explorer at http://explorer.msn.com/intl.asp. > Eduardo G.
