Neolamarckia cadamba (Roxb.) Bosser

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 (979 mm of 1345 mm) falls in June to September, warmer than the year (wet-season mean 27.2 °C against a yearly mean of 25.5 °C). Months are the habitat's, northern hemisphere; shifted six months for a southern-hemisphere collection: December to March.

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.

This species’ habitat figures, with their source.

1345 mm a year at the habitat, 979 mm of it June to September. Wettest month July at 303 mm, driest December at 12 mm. Across the envelope cells the year's total runs 834 mm to 3174 mm (10th to 90th percentile of each cell's own year) (median year across the envelope cells, CHELSA; habitat calendar, northern 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: 27 to 43 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 22, the highest 90th-percentile month 47).

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 10.4 °C, the absolute minimum 6.1 °C, no frost in 44 years (NASA POWER daily minima). Warmest: the 99th-percentile day is 44.7 °C. Monthly means: coldest night 15.1 °C in January (across the envelope cells 8.3 °C to 22.8 °C), warmest day 33.3 °C in April (median year across the envelope cells, CHELSA). Cold floor: 10.4 °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: 54 to 67% 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.
