Summary

Nepenthes izumiae is a tropical pitcher plant endemic to Sumatra, where it grows in montane forest at 1,700–1,900 m above sea level. It appears to be most closely related to N. lingulata and N. singalana.

About the genus · Nepenthes

Nepenthes is a genus of carnivorous plants, also known as tropical pitcher plants, or monkey cups, in the monotypic family Nepenthaceae. The genus includes about 170 species, and numerous natural and many cultivated hybrids. They are mostly liana-forming plants of the Old World tropics, ranging from South China, Indonesia, Malaysia, and the Philippines; westward to Madagascar and the Seychelles (one); southward to Australia (four) and New Caledonia (one); and northward to India (one) and Sri Lanka (one).

Cultivation

Grouped as a carnivorous plant by the genus Nepenthes, which is reliably one kind of plant (archetype table). The table holds no figure for this group, which spans too much for one minimum, and no habitat climate is derived yet; no cold floor is given, and no prose comes from the table.

Nothing derived: no habitat climate for this species, and the archetype table has no figure for its genus or family.

Climate across the habitat

No habitat climate can be derived: Only 2 distinct land cells of the climate grid hold an in-range record; three are needed for an envelope.

Natural habitat

Native range as published by WCVP; the marker is where the records are densest and decides nothing.
No openly licensed record to show inside the range.

Kew's description“liana” · “wet tropical”· quoted from WCVP, RBG Kew (CC BY 4.0); not derived here
Map marker0.05, 100.15 · in the densest population, 5 records (100% of those in range)
Evidence usedThe map marker rests on all 5 georeferenced records inside the native range; none carries a licence permitting republication, so the map shows no points. Under a dozen records: treat the map as indicative. No climate envelope is derived for this species. 3 in-range records are placed to worse than 10 km and stay on the map but off the climate.
The map markerthe map marker: the centre of the tenth-degree cell nearest the middle (no openly licensed record lies in the population, so no record's coordinates are published) of the densest 1° population of the 5 in-range records; it decides nothing.
