| Nepenthes macrovulgaris Turnbull & Middleton (1988) |
Nepenthes macrovulgaris (Latin: macro = large, vulgaris = common) is a species of pitcher plant. It is a lowland plant and grows at altitudes ranging from 500 to 800 m in sub-montane forest clearings and mossy forest. Its range is restricted to three mountains: Mount Kinabalu, Mount Tambuyukon 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 being the most common.[1][2]
[edit] Taxonomy
N. macrovulgaris is most closely related to N. hirsuta and N. hispida, and may be difficult to distinguish from them.
| 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 |
[edit] Etymology
Turnbull and Middleton, who described the species in 1988, explain that they chose the specific epithet macrovulgaris to:[3]
[...] indicate a relatively large plant and to indicate that no single characteristic uniquely distinguishes this taxon from all others. The suffix vulgaris does not indicate that this species is either common or ordinary. On the contrary, it is quite striking. The epithet is an irregular combination of Greek and Latin. The name was used in the field to identify living material which was distributed to growers and this informal name is now commonly used by collectors. We feel that to change the name now would create unnecessary confusion.
