About the genus · Commiphora

Commiphora is the most species-rich genus of flowering plants in the frankincense and myrrh family, Burseraceae. The genus contains approximately 190 species of shrubs and trees, which are distributed throughout the (sub-) tropical regions of Africa, the western Indian Ocean islands, the Arabian Peninsula, India, and South America. The genus is drought-tolerant and common throughout the xerophytic scrub, seasonally dry tropical forests, and woodlands of these regions.

Grouped as a cactus or succulent by the genus Commiphora, which is reliably one kind of plant (archetype table). Rain rule: a summer growing season, June to September in the northern hemisphere (December to March at the habitat, southern). Habitat rain 1072 mm a year, wettest January at 306 mm, driest July at 6 mm (habitat calendar, southern hemisphere). Open sky over the habitat: 30 to 45 mol/m²/day. Cold floor 15.1 °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 Commiphora, 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 summer growing season, June to September in the northern hemisphere (December to March at the habitat, southern).

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 (893 mm of 1072 mm) falls in December to March, warmer than the year (wet-season mean 26.9 °C against a yearly mean of 25.5 °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.

Rain Habitat rain 1072 mm a year, wettest January at 306 mm, driest July at 6 mm (habitat calendar, southern hemisphere).

1072 mm a year at the habitat, 893 mm of it December to March. Wettest month January at 306 mm, driest July at 6 mm. Across the envelope cells the year's total runs 710 mm to 1557 mm (10th to 90th percentile of each cell's own year) (median year across the envelope cells, CHELSA; habitat calendar, southern hemisphere).

Light Open sky over the habitat: 30 to 45 mol/m²/day.

This species’ habitat figures, with their source.

Open sky over the habitat: 30 to 45 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 28, 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.

Temperature

Coldest: the 1st-percentile night over 44 years at the typical cell is 15.1 °C, the absolute minimum 12.4 °C, no frost in 44 years (NASA POWER daily minima). Warmest: the 99th-percentile day is 38.7 °C. Monthly means: coldest night 19.2 °C in July (across the envelope cells 15.5 °C to 24.1 °C), warmest day 30.6 °C in November (median year across the envelope cells, CHELSA). Cold floor: 15.1 °C, which is the 1st-percentile night over 44 years at the typical cell (NASA POWER).

Natural habitat

Native range as published by WCVP; the marker is where the records are densest and decides nothing: the climate was read across every in-range record's cell, not at the marker.
