madagascariensis need high temperatures. Around 30°/35° by day, and around 25° by night is appreciated by this plant. In winter the temperature by night can fall at around 15°. Even if the plants are growing by the sea, plants are often found in some peat areas. The sphagnum is growing only on surface. The humidity is not quite so high. One day i recorded only 37% of humidity. Night is not too high, with around 75%. Important fact i think, the wind is really important for those 2 species, pervillei and madagascariensis. Every areas where you can find those nepenthes, they are exposed to it. and sun all the day long. Shade areas for madagascariensis is quite rare.
Here is one of the most amazing view for me, a meadow of madagascariensis.
--How close to the shore does N. madagascariensis grow ?
There are many kind areas where you can find it. Close to the splits in edge of sea, in the small valleys , or simply pure peat bogs.
--but are those Strelitzia nicolai in the background? Yes it is !
--are they grasses or sedges? Both in this peat bog.
--Was the ground wet? Just humid on the surface. The sphagnum was quite dry i could say too. Humid inside in the peat. I've seen other areas where the soil was very dry ( peat and sand ), and the madagascariensis seemed sick ( Small pitchers, and leaves sheets rolled up ). but has a few meters of in humid zone, the plants were just beautiful !

It is very encouraging to see these nepenthes growing near the sea. This would also be great plants for those living in shoreline regions where growing cp's might seem impossible. Perhaps breeding of shoreline species together could produce some exotic hybrids able to withstand salt air and salt water with ease. I think what you have shown here are excellent examples of the ways that nepenthes can truly adapt to almost any conditions presented to them. Thank you for an excellent report on these two little known species. Now, the next step would be to replace the weak clones already in cultivation wih what seems to be a sturdy plant probably more robust than N. alata!
