Nepenthes hamata is a tropical pitcher plant endemic to Sulawesi, where it grows at elevations of 1,400–2,500 m above sea level. The specific epithet hamata is derived from the Latin word hamatus, meaning "hooked". It describes the appearance of the highly developed peristome teeth of this species.

Nepenthes glabrata is a tropical pitcher plant endemic to Sulawesi. The species grows in open, high forest at elevations of 1,600 to 2,100 m. It produces dainty, colourful pitchers reaching only a few centimetres in height. These traps are red speckled on a yellowish background, giving them a "hand painted" appearance. The specific epithet glabrata is derived from the Latin word glaber, meaning "hairless", and refers to the mostly glabrous nature of this species.

Nepenthes macrovulgaris (; from Greek macro- "large" and Latin vulgaris "common, usual"), or the serpentine pitcher-plant, is a tropical pitcher plant endemic to Borneo. It is a lowland plant that typically grows at altitudes ranging from 300 to 1,200 m in sub-montane forest clearings and mossy forest. Its range is restricted to ultramafic habitats, including Mount Kinabalu, Mount Tambuyukon, the Danum Valley, the Tawai Range, the Meliau Range and Mount Silam, all in Sabah, Malaysian Borneo. Pitchers grow to around 25 cm high and range in colour from green to brown, with the speckled form
