Nepenthes hamata (pronounced /nəˈpɛnθiːz həˈmɑːtə/ or /ˈhæmɑːtə/, from Latin: hamatus = hooked) is a carnivorous pitcher plant species of the genus Nepenthes. It is endemic to Central Sulawesi where it grows as an epiphyte in mossy forest.
N. hamata is famous for having possibly the most developed peristome in the genus, which consists of expanded ribs that form long, curved "teeth" at the edge of the pitcher's mouth. The upper pitchers are usually more elongated and the peristome is even more developed, with the "teeth" curving completely outwards.
N. hamata belongs to what has been called the "Hamata group", which also includes four other closely related species from Borneo and Sulawesi: N. glabrata, N. muluensis, N. murudensis, and N. tentaculata.[1]
[edit] Forms and varieties
Two distinct forms of N. hamata are known: the typical form and a "red hairy" variety. The plants pictured are examples of the former. The other, recently discovered, variety bears a thick indumentum of rusty red/brown hairs that covers its pitchers. It has yet to be formally described.
