Photographs by Alexandre Antoine showing Nepenthes madagascariensis in habitat.

"All the plants grew in a very wet acidic sandy soil with peat moss and sphagnum (1/2 quartz sand, 1/2 peat moss), completely covered by 2 to 5 cm of water. In this area, the sun always is very strong and day temperature can often be up to 35°C all over the year. At night, it falls down to a minimum of 18°C. Moreover, I noticed air humidity could be very low during the day (down to an average of 35-40%) but it becomes always much higher (75-90%) once the twighlight comes. It may be the reason why the digestive liquid inside the pitchers was so concentrated..." (Alexandre Antoine)

"All plants of N. madagascariensis I found there were well developped adults (till 2 meters high) with lots of yellow-green upper pitchers (the biggest pitcher I've seen mesured 19 cm) or young adults of at least 30-40 cm high with only 1 to 3 deep red lower pitchers of 8-12 cm." (Alexandre Antoine)
