Hi again..recently i visited another rafflesiana site,a heath forest. During rainy season this area will be flooded.The ground here is very soft. I use my machete ( 14" long ) easily trust deep down to reveal the water level and soil substrates.On top are very thin layer of rotting leaves and beneath are loose sand and clay. Conditions is strictly lowland with day temp ranging 28°C - 30°C. RH 80%
In the book "National parks of Sarawak' by Drs Hans Hazebroek, a trained geologist, he described the geological structure of this part as alluvium:sand,silt deposits,and clay. Land elevation above sea level 0 - 75m
On slightly higher groung,moss grows over it,ground is dryer as water seeps through the substrates with ease.
As silt,clay and sand are loose and easily erode thus revealing the more sandy lower part of the ground.
Rafflesianas here are very diversified with a variety of variation ,included those i posted some months ago, the not very common nigropurpurea,and nivea with dark red peristome.
