Summary
Heliodendron basalticum is a species of tree native to the dry rainforests of Queensland, Australia.
Quoted from Wikipedia, "Heliodendron basalticum", CC BY-SA 4.0.
Cultivation
Seasons
The rain rule reads a summer growing season: 70% of the median year's rain (427 mm of 578 mm) falls in November to April, warmer than the year (wet-season mean 26.0 °C against a yearly mean of 22.3 °C). Months are the habitat's, southern hemisphere; shifted six months for a northern-hemisphere collection: May to October.
Rain
578 mm in the median year at the habitat, 427 mm of it November to April. Wettest month January at 98 mm, driest month September at 16 mm. Across the grid cells of the range the year's total runs 470 mm to 730 mm, the 10th to 90th percentile of each cell's own year. The median of the cells' own yearly totals, 596 mm, is the year's rain at the top of the page; the 578 mm here is the median year's, the twelve monthly medians added, which the rain rule reads. Habitat calendar, southern hemisphere; median year across the grid cells of the range, CHELSA.
Light
Open sky over the habitat: 25 to 45 mol/m²/day across the year (daily light integral, median year across the grid cells of the range, CHELSA; the lowest 10th-percentile month across the cells is 23, the highest 90th-percentile month 48).
Warmth and air
Coldest: the 1st-percentile night over 44 years at a typical spot in the range is 3.2 °C, the absolute minimum 0.2 °C, no frost in 44 years (NASA POWER daily minima). Warmest: the 99th-percentile day is 44.4 °C. Monthly means: the coldest month's mean nightly low 9.4 °C in July (across the grid cells of the range 7.4 °C to 11.6 °C), the warmest month's mean daily high 33.2 °C in December (median year across the grid cells of the range, CHELSA). Cold floor: 3.2 °C, which is the 1st-percentile night over 44 years at a typical spot in the range (NASA POWER).
Relative humidity at the habitat: 47 to 55% across the year (monthly means, median year across the grid cells of the range, CHELSA). A figure about the air, saying nothing about how the plant takes water.
How this section is made
Each card states this species' habitat figures with their sources, and what two fixed rules read from them; nothing here says what the plant does, wants or tolerates. The rules · the terms.
Seasons. Read from the median year of CHELSA monthly rainfall and mean temperature across the grid cells of the range: 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 moves 4 °C or more and the habitat lies 10° or more from the equator. A reading of the curves, not an observation of the plant.
Rain. CHELSA monthly precipitation, median year across the grid cells of the range. The rain that falls where the species is recorded; nothing about how the plant takes water.
Light. 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.
Temperature. NASA POWER daily minima and maxima over 44 years at a typical spot in the range, lapse-corrected -11 m to its elevation; CHELSA monthly means, median year across the grid cells of the range. The cold floor is the 1st-percentile night named in its sentence. Not a measured survival limit for any plant in a pot.
Humidity. CHELSA relative humidity, median year across the grid cells of the range.
Climate across the habitat
Habitat months, southern hemisphere
Mean daily high from 21 °C in Jun and Jul to 33 °C in Jan and Dec; mean nightly low from 9 °C in Jul to 22 °C in Jan, Feb and Dec. The cold quarter, Jun to Aug, is the three months around the coldest month's mean nightly low. 578 mm of rain in the median year (the twelve monthly medians added), the wettest month Jan. The bands show the 10th to 90th percentile across 238 habitat cells. Over 44 years at a typical spot in the range (NASA POWER) the absolute minimum was 0.2 °C and the 99th-percentile day 44.4 °C; neither is dated to a month. Beneath: daily light integral and relative humidity through the year, each on its own scale.
