Summary

Aloinopsis malherbei is a species of succulent plant, also known as the giant jewel plant. It is native to the Cape Provinces of South Africa, especially the area around Calvinia and Loeriesfontein. The plant produces a thick tuber and produces yellow flowers. Unlike other Aloinopsis, it only has tubercles (bumps) at the leaf tips.

Grouped as a cactus or succulent by the genus Aloinopsis, which is reliably one kind of plant (archetype table). Rain rule: a winter growing season, September to March in the northern hemisphere (March to September at the habitat, southern). Habitat rain 242 mm a year, wettest July at 32 mm, driest January at 6 mm (habitat calendar, southern hemisphere). Open sky over the habitat: 20 to 56 mol/m²/day. Cold floor -0.3 °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.

Also known as Nananthus malherbei L.Bolus.

Cultivation

Grouped as a cactus or succulent by the genus Aloinopsis, 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 winter growing season, September to March in the northern hemisphere (March to September at the habitat, southern).

This species’ habitat figures, and what two fixed rules read from them.

The rain rule reads a winter growing season: 70% of the year's rain (180 mm of 242 mm) falls in March to September, cooler than the year (wet-season mean 14.4 °C against a yearly mean of 17.0 °C). Months are the habitat's, southern hemisphere; shifted six months for a northern-hemisphere collection: September 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.

Rain Habitat rain 242 mm a year, wettest July at 32 mm, driest January at 6 mm (habitat calendar, southern hemisphere).

This species’ habitat figures, with their source.

242 mm a year at the habitat, 180 mm of it March to September. Wettest month July at 32 mm, driest January at 6 mm. Across the envelope cells the year's total runs 196 mm to 272 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.

Light Open sky over the habitat: 20 to 56 mol/m²/day.

Open sky over the habitat: 20 to 56 mol/m²/day across the year (daily light integral, median year across the envelope cells, CHELSA).

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.

Warmth and air Cold floor -0.3 °C (1st-percentile habitat night, NASA POWER).

This species’ habitat figures, with their source.

Temperature

Coldest: the 1st-percentile night over 44 years at the typical cell is -0.3 °C, the absolute minimum -3.6 °C, about 5 frost nights a year (NASA POWER daily minima). Warmest: the 99th-percentile day is 39.5 °C. Monthly means: coldest night 4.4 °C in July (across the envelope cells 4.3 °C to 4.8 °C), warmest day 31.6 °C in February (median year across the envelope cells, CHELSA). Cold floor: -0.3 °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.

Humidity

Relative humidity at the habitat: 49 to 53% 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.

Climate across the habitat

Habitat climate through the yearMean day from 17 °C in Jul to 32 °C in Feb; mean night from 4 °C in Jul to 15 °C in Feb. The cold quarter, Jun to Aug, is the three months around the coldest night. 242 mm of rain a year, most in Jul. The bands show the 10th to 90th percentile across 8 habitat cells. Over 44 years at the typical cell the absolute minimum was -3.6 °C and the 99th-percentile day 39.5 °C; neither is dated to a month.

Each figure is the median across the 8 grid cells holding the 11 in-range records, with the 10th–90th percentile span across those cells after the slash where it differs. Extremes and elevation were read at the typical cell 2417:3993 (-30.875, 19.675). Over 44 years there: absolute minimum -3.6 °C, 1st-percentile night -0.3 °C, 99th-percentile day 39.5 °C. Normals: CHELSA V2.1 1981–2010 climatology, 0.05° cells (each the mean of ~36 1 km pixels). Envelope: median and 10th–90th percentile of each month across the 8 distinct grid cells holding the 11 in-range records; extremes and elevation at the typical cell 2417:3993 (its coldest month's mean night nearest the median across cells); its position is the cell centre. Extremes: NASA POWER (MERRA-2) daily 1981–2024, cell -31.00_19.375, lapse-corrected +188 m at 6.5 °C/km. Elevation: ETOPO 2022, 901 m (cell mean).

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.
Openly licensed records inside the range, framed on where they fall.

Similar habitat climate the 6 species whose habitat climate is nearest this one's: mean day and night, month by month, and rain on a log scale, in calendar order, so a habitat with the same seasons six months out is far, not near. Nothing else counts: not range, not family.
