Melaleuca cajuputi Powell

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 (1134 mm of 1461 mm) falls in December to March, warmer than the year (wet-season mean 27.9 °C against a yearly mean of 27.0 °C). Months are the habitat's, southern hemisphere; shifted six months for a northern-hemisphere collection: June 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.

1461 mm a year at the habitat, 1134 mm of it December to March. Wettest month January at 325 mm, driest July at 3 mm; 3 months under 5 mm. Across the envelope cells the year's total runs 1094 mm to 2509 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.

Open sky over the habitat: 31 to 44 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 27, the highest 90th-percentile month 46).

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.

Coldest: the 1st-percentile night over 44 years at the typical cell is 19.1 °C, the absolute minimum 16.2 °C, no frost in 44 years (NASA POWER daily minima). Warmest: the 99th-percentile day is 32.4 °C. Monthly means: coldest night 20.2 °C in July (across the envelope cells 17.4 °C to 24.2 °C), warmest day 32.6 °C in November (median year across the envelope cells, CHELSA). Cold floor: 19.1 °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.

Relative humidity at the habitat: 55 to 65% 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.
