Nepenthes hirsuta (/nɪˈpɛnθiːz hərˈsjuːtə/; from Latin: hirsūtus "hairy, bristly"), the hairy pitcher-plant,[3] is a tropical pitcher plant endemic to Borneo. It is characterised by an indumentum of thick brown hairs, which is even present on the inflorescence. Pitchers are mostly green throughout with some having red blotches on the inside surfaces.[4]
N. hirsuta grows at an elevation of 200–1100 m.[5] It is present in a wide range of habitats, including kerangas forest, mossy banks in lower montane forest, open areas, and disturbed vegetation on lower ridges. It grows mostly on sandstone substrates.[4]
Taxonomy
N. hirsuta is most closely related to N. hispida and N. macrovulgaris. Botanists Matthew Jebb and Martin Cheek suggest that N. hirsuta is also related to N. philippinensis, a species endemic to Palawan in the Philippines .[6][7]
Morphological differences between N. macrovulgaris, N. hirsuta and N. hispida (Steiner, 2002 after Clarke, 1997) N. macrovulgaris N. hirsuta N. hispida leaves charteous ≤30 cm, oblong to linear leaves coriaceous ≤20 cm, canaliculate-spathulate or obovate leaves coriaceous sessile ≤28 cm, oblanceolate-oblongate apex acute to obtuse apex acute or roundish apex acuminate-obtuse, often unequal base attenuate into a winged petiole, wings wider towards the base, clasping stem for about half its diameter, not decurrent base attenuate, forming laterally flattened, semi-amplexicaul sheath base attenuate, amplexicaul and often decurrent onto the internode longitudinal veins: 2-3 on each side longitudinal veins not prominent longitudinal veins: 3 on each side adult pitchers and stem glabrous, young pitchers with short, thin hairs stem densely covered with long brown hairs, not as bristle-like as those of N. hispida stem very densely covered with bristle-like purple-grey hairs
In his Carnivorous Plant Database, taxonomist Jan Schlauer treats N. hispida as a heterotypic synonym of N. hirsuta.[8]
