Summary

Drosera nidiformis is a tropical African sundew. This plant is indigenous to KwaZulu-Natal in South Africa. Its classification is ambiguous; some sources refer to it as a synonym of Drosera dielsiana whereas others treat it as a separate species. This plant was previously known as Drosera "maglisburg".

About the genus · Drosera

Drosera, which is commonly known as the sundews, is one of the largest genera of carnivorous plants, with at least 194 species. These members of the family Droseraceae lure, capture, and digest insects using stalked mucilaginous glands covering their leaf surfaces. The insects are used to supplement the poor mineral nutrition of the soil in which the plants grow. More on Wikipedia ›

Grouped as a carnivorous plant by the genus Drosera, which is reliably one kind of plant (archetype table). Rain rule: a summer growing season, March to September in the northern hemisphere (September to March at the habitat, southern). Habitat rain 1288 mm a year, wettest January at 162 mm, driest June at 45 mm (habitat calendar, southern hemisphere). Open sky over the habitat: 19 to 37 mol/m²/day. Cold floor 13.4 °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 Drosera, 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 summer growing season, March to September in the northern hemisphere (September to March at the habitat, southern).

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

The rain rule reads a summer growing season: 70% of the year's rain (1003 mm of 1288 mm) falls in September to March, warmer than the year (wet-season mean 21.0 °C against a yearly mean of 19.8 °C). Months are the habitat's, southern hemisphere; shifted six months for a northern-hemisphere collection: March to September.

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.

1288 mm a year at the habitat, 1003 mm of it September to March. Wettest month January at 162 mm, driest June at 45 mm. Across the envelope cells the year's total runs 1209 mm to 1334 mm (10th to 90th percentile of each cell's own year) (median year across the envelope cells, CHELSA; habitat calendar, southern hemisphere).

Temperature

Coldest: the 1st-percentile night over 44 years at the typical cell is 13.4 °C, the absolute minimum 10.1 °C, no frost in 44 years (NASA POWER daily minima). Warmest: the 99th-percentile day is 27.3 °C. Monthly means: coldest night 12.8 °C in July (across the envelope cells 12.4 °C to 14.1 °C), warmest day 25.1 °C in February (median year across the envelope cells, CHELSA). Cold floor: 13.4 °C, which is the 1st-percentile night over 44 years at the typical cell (NASA POWER).

Each figure is the median across the 10 grid cells holding the 16 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 2425:4198 (-31.275, 29.925). Over 44 years there: absolute minimum 10.1 °C, 1st-percentile night 13.4 °C, 99th-percentile day 27.3 °C.

Natural habitat

Native range as published by WCVP; the marker is where the records are densest and decides nothing: the climate was read across every in-range record's cell, not at the marker.
