Summary

Drosera pygmaea is a carnivorous, rosette-forming biennial or annual species of herb native to Australia and New Zealand. The specific epithet, which translates as "dwarf" from Latin, is a reference to the very small size of this plant, which grows to between 8 and 18 mm in diameter. Small, pale flowers are produced at the ends of 1- to 3-inch stems. It is perhaps the most well-known of the pygmy sundews. More on Wikipedia ›

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: no season, 70% of the rain takes 8 months (October to May in the northern hemisphere). Habitat rain 839 mm a year, wettest June at 93 mm, driest February at 44 mm (habitat calendar, southern hemisphere). Open sky over the habitat: 12 to 45 mol/m²/day. Cold floor 4.0 °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: no season, 70% of the rain takes 8 months (October to May in the northern hemisphere).

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

The rain rule reads no season: 70% of the year's rain (617 mm of 839 mm) takes 8 months, April to November. Mean temperature moves 8.7 °C between the warmest and coldest month. Months are the habitat's, southern hemisphere; shifted six months for a northern-hemisphere collection: October to May.

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 839 mm a year, wettest June at 93 mm, driest February at 44 mm (habitat calendar, southern hemisphere).

This species’ habitat figures, with their source.

839 mm a year at the habitat, 617 mm of it April to November. Wettest month June at 93 mm, driest February at 44 mm. Across the envelope cells the year's total runs 599 mm to 1543 mm (10th to 90th percentile of each cell's own year) (median year across the envelope cells, CHELSA; habitat calendar, southern hemisphere).

CHELSA monthly precipitation, median year across the envelope cells. The rain that falls where the species is recorded; nothing about how the plant takes water.

Light Open sky over the habitat: 12 to 45 mol/m²/day.

This species’ habitat figures, with their source.

Open sky over the habitat: 12 to 45 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 9, the highest 90th-percentile month 49).

CHELSA shortwave radiation at each envelope cell, a daily-mean flux taken to a daily total and converted at 2.07 mol of PAR per MJ. The sky over the habitat, measured; what reaches a plant under a rock, a shrub or a shade cloth is not.

Warmth and air Cold floor 4.0 °C (1st-percentile habitat night, NASA POWER).

Temperature

Coldest: the 1st-percentile night over 44 years at the typical cell is 4.0 °C, the absolute minimum 0.5 °C, no frost in 44 years (NASA POWER daily minima). Warmest: the 99th-percentile day is 34.7 °C. Monthly means: coldest night 7.1 °C in July (across the envelope cells 3.3 °C to 10.6 °C), warmest day 22.7 °C in February (median year across the envelope cells, CHELSA). Cold floor: 4.0 °C, which is the 1st-percentile night over 44 years at the typical cell (NASA POWER).

NASA POWER daily minima and maxima 1981–2024 at the typical cell, lapse-corrected to its elevation; CHELSA monthly means, median year across the envelope cells, CHELSA. The cold floor is the figure named in its sentence. Not a measured survival limit for any plant in a pot.

Humidity

Relative humidity at the habitat: 59 to 62% across the year (monthly means, median year across the envelope cells, CHELSA). A figure about the air, saying nothing about how the plant takes water.

Climate across the habitat

Habitat climate through the yearMean day from 12 °C in Jul to 23 °C in Feb; mean night from 7 °C in Jul to 15 °C in Feb. The cold quarter, Jun to Aug, is the three months around the coldest night. 839 mm of rain a year, most in Jun. The bands show the 10th to 90th percentile across 985 habitat cells. Over 44 years at the typical cell the absolute minimum was 0.5 °C and the 99th-percentile day 34.7 °C; neither is dated to a month.

Each figure is the median across the 985 grid cells holding the 1726 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 2561:6428 (-38.075, 141.425). Over 44 years there: absolute minimum 0.5 °C, 1st-percentile night 4.0 °C, 99th-percentile day 34.7 °C.
