Summary

Drosera scorpioides, commonly called the shaggy sundew, is a pygmy sundew native to the Jarrah Forest region and southern coasts of Southwest Australia. Notable for its unusually large size relative to other pygmy sundews, D. scorpioides can produce rosettes measuring up to two inches in diameter and specimens may attain a height of up to 100 millimeters. The species is found on white sand and clay, near swamps, on sand ridges, and is associated with laterite. The flowers are pink and white, appearing sometime between August and October.

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 winter growing season, October to April in the northern hemisphere (April to October at the habitat, southern). Habitat rain 524 mm a year, wettest July at 71 mm, driest February at 20 mm (habitat calendar, southern hemisphere). Open sky over the habitat: 15 to 47 mol/m²/day. Cold floor 3.7 °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 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 winter growing season, October to April in the northern hemisphere (April to October at the habitat, southern).

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

The rain rule reads a winter growing season: 70% of the year's rain (392 mm of 524 mm) falls in April to October, cooler than the year (wet-season mean 13.3 °C against a yearly mean of 15.5 °C). Months are the habitat's, southern hemisphere; shifted six months for a northern-hemisphere collection: October to April.

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 524 mm a year, wettest July at 71 mm, driest February at 20 mm (habitat calendar, southern hemisphere).

524 mm a year at the habitat, 392 mm of it April to October. Wettest month July at 71 mm, driest February at 20 mm. Across the envelope cells the year's total runs 432 mm to 792 mm (10th to 90th percentile of each cell's own year) (median year across the envelope cells, CHELSA; habitat calendar, southern hemisphere).

Open sky over the habitat: 15 to 47 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 14, the highest 90th-percentile month 52).

Temperature

Coldest: the 1st-percentile night over 44 years at the typical cell is 3.7 °C, the absolute minimum 0.8 °C, no frost in 44 years (NASA POWER daily minima). Warmest: the 99th-percentile day is 40.3 °C. Monthly means: coldest night 7.5 °C in July (across the envelope cells 5.4 °C to 10.2 °C), warmest day 25.7 °C in February (median year across the envelope cells, CHELSA). Cold floor: 3.7 °C, which is the 1st-percentile night over 44 years at the typical cell (NASA POWER).
