Summary

Nepenthes kitanglad is a tropical pitcher plant native to the Philippines. It is known only from Mount Kitanglad in Bukidnon Province, Mindanao, where it has been recorded as an epiphyte in mossy forest at 1,800–2,100 m altitude. This species belongs to the informal "N. alata group", which also includes N. alata, N. ceciliae, N. copelandii, N. extincta, N. graciliflora, N. hamiguitanensis, N. kurata, N. leyte, N. mindanaoensis, N. negros, N. ramos, N. saranganiensis, and N. ultra. These species are united by a number of morphological characters, including winged petioles, lids with basal ridges on the lower surface, and upper pitchers that are usually broadest near the base.

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: a sharp rainy season, May to October at the habitat (not shifted); the temperature curve is flat (1.7 °C of range), so no growing season is inferred. Habitat rain 3084 mm a year, wettest September at 411 mm, driest February at 128 mm (habitat calendar, northern hemisphere). Open sky over the habitat: 25 to 37 mol/m²/day. Cold floor 9.5 °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: a sharp rainy season, May to October at the habitat (not shifted); the temperature curve is flat (1.7 °C of range), so no growing season is inferred.

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

The rain rule reads a sharp season: 70% of the year's rain (2165 mm of 3084 mm) falls in May to October. The temperature curve is flat, 1.7 °C between the warmest and coldest month, so the growing-season rule does not infer a growing season from it. 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 3084 mm a year, wettest September at 411 mm, driest February at 128 mm (habitat calendar, northern hemisphere).

3084 mm a year at the habitat, 2165 mm of it May to October. Wettest month September at 411 mm, driest February at 128 mm.

Temperature

Coldest: the 1st-percentile night over 44 years at the typical cell is 9.5 °C, the absolute minimum 7.0 °C, no frost in 44 years (NASA POWER daily minima). Warmest: the 99th-percentile day is 26.2 °C. Monthly means: coldest night 12.4 °C in February (across the envelope cells 8.9 °C to 13.1 °C), warmest day 21.3 °C in April (median year across the envelope cells, CHELSA). Cold floor: 9.5 °C, which is the 1st-percentile night over 44 years at the typical cell (NASA POWER).
