N. rhombicaulis lower pitcher
This species is a good terrarium candidate, due to its small size.  However, one should try to keep it cool at night, in keeping with its highland origins.  Pitchers are colorful, and relatively long-lived.  Rate of growth is fairly rapid.  Produces basal shoots readily.
