With knife-sharp hooks for a peristome, Nepenthes hamata is, hands-down, the most vicious looking tropical pitcher plant. If I were an insect or small mammal, I’d refer to this as a Nope-enthes. The name, hamata, comes from the Latin word hamatus, meaning “hooked.” Appropriate. It’s a highland variety from Sulawesi, growing at elevations between 4600-8300 feet (1400-2500 m) above sea level where it strikes fear into the hearts of insects and small animals.
Dutch botanist Pierre Joseph Eyma collected the Nepenthes hamata samples in 1938 that were later used to anchor the type specimen (typical version of the plant used to define the species). However, it wasn’t until 1984 that two formal descriptions of N. hamata were published almost simultaneously by Shigeo Kurata and John R. Turnbull and Anne T. Middleton. Turnbull and Middleton named it N. hamatus in the journal Reinwardtia, while Kurata named the plant N. dentata (respect the teeth) in The Garden’s Bulletin. Kurata first witnessed the plant in 1972 on a trip to Herbarium Bogoriense:
During my stay at the Herbarium Bogoriense in 1972, for the study of their Nepenthes collection, I was able to examine much undetermined material from several Indonesian islands. While going through those collected by P. J. Eyma in Sulawesi, I came across a very interesting Nepenthes. After subsequent study, I am now able to conclude that it should be described as a new species.
Kurata’s name, N. dentata, was first published in his 1976 book, Nepenthes of Mount Kinabalu, where he acknowledged its existence and yet noted it as “not yet established.” In the end, a feminized name (to reflect the female plant described) closer to Middleton and Turnbull’s N. hamatus won out, but let’s be honest – they’re both appropriate for this toothy monster of a tropical pitcher plant.
