Nepenthes hamata is renown for having the most fearsome teeth of any Nepenthes species. It is a highland plant requiring warm days and cool nights with good light and humidity. The Tambusisi form may have the darkest and most sinister-looking lower pitchers of any of the hamata forms. Horticultural seed was produced at Borneo Exotics and then put into tissue culture and these are the resulting plants. Plants have red leaves when young.
