N.belii is a nice lowland species from the Philippines , or more precisely from Mindanao.  Kondo described this species in 1969. This species is found  at altitudes of 250m to 800m.

Nepenthes belii will grow well in typical lowland conditions. My plant seems to appreciate LFS. In my conditions, pitchers measure 6cm to 11cm.

I recommend this species, because it stays relatively small and hence, is ideal in a terrarium
