Nepenthes Macrovulgaris - Taxonomy

Taxonomy

Nepenthes macrovulgaris is most closely related to N. hirsuta and N. hispida, and may be difficult to distinguish from them. Botanists Matthew Jebb and Martin Cheek suggest that N. macrovulgaris is also related to N. philippinensis, a species endemic to Palawan in the Philippines.

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 ½ 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
