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

Grouped as a cactus or succulent by the genus Dorstenia, which is reliably one kind of plant (archetype table). Rain rule: a sharp rainy season, March to June and September to October at the habitat (not shifted); the temperature curve is flat (2.4 °C of range), so no growing season is inferred. Habitat rain 2362 mm a year, wettest October at 429 mm, driest January at 47 mm (habitat calendar, northern hemisphere). Open sky over the habitat: 23 to 32 mol/m²/day. Cold floor 18.6 °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 cactus or succulent by the genus Dorstenia, 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, March to June and September to October at the habitat (not shifted); the temperature curve is flat (2.4 °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 (1680 mm of 2362 mm) falls in March to June and September to October. The temperature curve is flat, 2.4 °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.

2362 mm a year at the habitat, 1680 mm of it March to June and September to October. Wettest month October at 429 mm, driest January at 47 mm. Across the envelope cells the year's total runs 1716 mm to 3632 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: 23 to 32 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 19, the highest 90th-percentile month 35).

Temperature

Coldest: the 1st-percentile night over 44 years at the typical cell is 18.6 °C, the absolute minimum 14.4 °C, no frost in 44 years (NASA POWER daily minima). Warmest: the 99th-percentile day is 37.1 °C. Monthly means: coldest night 21.1 °C in July (across the envelope cells 19.0 °C to 23.0 °C), warmest day 29.2 °C in February (median year across the envelope cells, CHELSA). Cold floor: 18.6 °C, which is the 1st-percentile night over 44 years at the typical cell (NASA POWER).
