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 ›

In short condensed by rule from the cultivation cards · not written by a person

Grouped as a carnivorous plant by the genus Drosera, which is reliably one kind of plant (archetype table). Rain rule: a sharp rainy season, December to January and April to August at the habitat (not shifted); the temperature curve is flat (2.1 °C of range), so no growing season is inferred. Habitat rain 2551 mm a year, wettest June at 368 mm, driest October at 130 mm (habitat calendar, northern hemisphere). Open sky over the habitat: 27 to 37 mol/m²/day. Cold floor 17.6 °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 sharp rainy season, December to January and April to August at the habitat (not shifted); the temperature curve is flat (2.1 °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 (1854 mm of 2551 mm) falls in December to January and April to August. The temperature curve is flat, 2.1 °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 2551 mm a year, wettest June at 368 mm, driest October at 130 mm (habitat calendar, northern hemisphere).

2551 mm a year at the habitat, 1854 mm of it December to January and April to August. Wettest month June at 368 mm, driest October at 130 mm. Across the envelope cells the year's total runs 2066 mm to 3607 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: 27 to 37 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 24, the highest 90th-percentile month 38).

Temperature

Coldest: the 1st-percentile night over 44 years at the typical cell is 17.6 °C, the absolute minimum 14.4 °C, no frost in 44 years (NASA POWER daily minima). Warmest: the 99th-percentile day is 36.6 °C. Monthly means: coldest night 18.8 °C in January (across the envelope cells 15.5 °C to 21.0 °C), warmest day 28.1 °C in October (median year across the envelope cells, CHELSA). Cold floor: 17.6 °C, which is the 1st-percentile night over 44 years at the typical cell (NASA POWER).

Each figure is the median across the 49 grid cells holding the 77 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 1681:2355 (5.925, -62.225). Over 44 years there: absolute minimum 14.4 °C, 1st-percentile night 17.6 °C, 99th-percentile day 36.6 °C. Normals: CHELSA V2.1 1981–2010 climatology, 0.05° cells (each the mean of ~36 1 km pixels). Envelope: median and 10th–90th percentile of each month across the 49 distinct grid cells holding the 77 in-range records; extremes and elevation at the typical cell 1681:2355 (its coldest month's mean night nearest the median across cells); its position is the cell centre. Extremes: NASA POWER (MERRA-2) daily 1981–2024, cell 6.00_-62.500, lapse-corrected -317 m at 6.5 °C/km. Elevation: ETOPO 2022, 558 m (cell mean).

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.
