Summary

Nepenthes sanguinea is a large and vigorous Nepenthes pitcher plant species, native to Peninsular Malaysia and southernmost Thailand, where it grows at 300–1,800 metres altitude. It is primarily a terrestrial species, but can grow as an epiphyte in the wet biome of upper montane forests. The pitchers are variable in size, from 10–30 cm tall, and range from green and yellow to orange and red. The insides of the pitchers are usually speckled with its two main colors.

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).

Grouped as a carnivorous plant by the genus Nepenthes, which is reliably one kind of plant (archetype table). Rain rule: no season, 70% of the rain takes 8 months (March to May and August to December at the habitat (not shifted)). Habitat rain 3304 mm a year, wettest November at 382 mm, driest February at 179 mm (habitat calendar, northern hemisphere). Open sky over the habitat: 24 to 34 mol/m²/day. Cold floor 14.7 °C (1st-percentile habitat night, NASA POWER).

Each sentence is one card's own one-line form, written by the same rule as the card (Its year, Rain, Light, Temperature); the note cannot say what a card does not. Months are given for the northern hemisphere (set your site in Settings to change this), and the habitat's own alongside. The cards · the figures.

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; the cold floor is the habitat's alone, and no prose comes from the table.

Its year Rain rule: no season, 70% of the rain takes 8 months (March to May and August to December at the habitat (not shifted)).

This species’ habitat figures, and what two fixed rules read from them.

The rain rule reads no season: 70% of the year's rain (2501 mm of 3304 mm) takes 8 months, March to May and August to December. Mean temperature moves 1.7 °C between the warmest and coldest month. Months are the habitat's, northern hemisphere, within 10° of the equator; with no thermal season there there is no season to reverse, so they are not shifted for a collection elsewhere.

Read from the median year of CHELSA monthly rainfall and mean temperature across the envelope cells: the rain rule takes the smallest set of months carrying 70% of the rain and calls it winter when its mean is more than half a degree below the year's, summer when more than that above, and neither in between; the temperature rule, used only under 120 mm, names the cooler six months when they are at least a degree cooler than the other six. Months are shifted for the other hemisphere only where the temperature curve gives a season to reverse. A reading of the curves, not an observation of the plant.

Rain Habitat rain 3304 mm a year, wettest November at 382 mm, driest February at 179 mm (habitat calendar, northern hemisphere).

3304 mm a year at the habitat, 2501 mm of it March to May and August to December. Wettest month November at 382 mm, driest February at 179 mm. Across the envelope cells the year's total runs 2966 mm to 3962 mm (10th to 90th percentile of each cell's own year) (median year across the envelope cells, CHELSA; habitat calendar, northern hemisphere).

Open sky over the habitat: 24 to 34 mol/m²/day across the year (daily light integral, median year across the envelope cells, CHELSA; the lowest 10th-percentile month across the cells is 20, the highest 90th-percentile month 35).

Temperature

Coldest: the 1st-percentile night over 44 years at the typical cell is 14.7 °C, the absolute minimum 12.2 °C, no frost in 44 years (NASA POWER daily minima). Warmest: the 99th-percentile day is 27.2 °C. Monthly means: coldest night 16.9 °C in January (across the envelope cells 13.2 °C to 20.9 °C), warmest day 25.9 °C in April (median year across the envelope cells, CHELSA). Cold floor: 14.7 °C, which is the 1st-percentile night over 44 years at the typical cell (NASA POWER).

Each figure is the median across the 18 grid cells holding the 27 in-range records, with the 10th–90th percentile span across those cells after the slash where it differs. Extremes and elevation were read at the typical cell 1726:5635 (3.675, 101.775). Over 44 years there: absolute minimum 12.2 °C, 1st-percentile night 14.7 °C, 99th-percentile day 27.2 °C.
