About the genus · Begonia

Begonia is a genus of perennial flowering plants in the family Begoniaceae. The genus contains more than 2,000 different plant species, distributed primarily across tropical and subtropical regions of Africa, Asia, and Central and South America, with Africa considered the center of origin. Some species are commonly grown indoors as ornamental houseplants in cooler climates, or cultivated outside in summertime for their bright colorful flowers, which have petals but no sepals.

Cultivation

Grouped as a tropical foliage plant, listed under the genus Begonia in the archetype table, and Kew describes it as “epiphytic subshrub or shrub”, “wet tropical”.

Seasons

The rain rule reads a sharp season: 70% of the median year's rain (1,439 mm of 1,961 mm) falls in January, March to May and September to November. The temperature curve is flat, 2.4 °C between the warmest and coldest month, so the growing-season rule does not infer a growing season from it. Months are the habitat's, northern hemisphere. The habitat lies within 10° of the equator, where the shift rule does not apply, so they are not shifted for a collection elsewhere.

Rain

1,961 mm in the median year at the habitat, 1,439 mm of it January, March to May and September to November. Wettest month October at 240 mm, driest month July at 70 mm. Across the grid cells of the range the year's total runs 1,527 mm to 3,905 mm, the 10th to 90th percentile of each cell's own year. The median of the cells' own yearly totals, 1,825 mm, is the year's rain at the top of the page; the 1,961 mm here is the median year's, the twelve monthly medians added, which the rain rule reads. Habitat calendar, northern hemisphere; median year across the grid cells of the range, CHELSA.

Light

Open sky over the habitat: 32 to 35 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 22, the highest 90th-percentile month 38).

Warmth and air
Temperature

Monthly means: the coldest month's mean nightly low 20.4 °C in July and August (across the grid cells of the range 13.3 °C to 23.2 °C), the warmest month's mean daily high 26.9 °C in March (median year across the grid cells of the range, CHELSA). Cold floor: none read. The nearest figure is 20.4 °C, the coldest month's mean nightly low, July and August, in the median year (CHELSA); a month's mean of its nightly lows is warmer than the nights a floor is read from. The daily extremes were read at a weather cell that is mostly sea and are not used.

Humidity

Relative humidity at the habitat: 70 to 73% 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. CHELSA monthly means, median year across the grid cells of the range. No cold floor is read without a daily extremes series; the coldest month's mean nightly low named in its sentence is not one. Not a measured survival limit for any plant in a pot.

Humidity. CHELSA relative humidity, median year across the grid cells of the range.

Group. Listed under the genus Begonia in the archetype table, and Kew describes it as “epiphytic subshrub or shrub”, “wet tropical”. A group is taken only where Kew's description of the species agrees with the table's listing. The table gives no figure and no prose; the cold floor is the habitat's alone.

Climate across the habitat

From few records: this habitat climate is read from 10 records in 8 grid cells; a page says so under 12 records or 5 cells, and shows the figures as read.

Habitat months, northern hemisphere

The daily extremes were read at a NASA POWER cell that is 8% land: neither it nor the next candidates whose coldest month's mean nightly low is within 2 °C of the median across cells sit in a POWER cell that is mostly land, and the rule reads a cold floor only from a cell that is mostly land, so none is read for this species. Nor is the coldest month's mean nightly low taken as one: it is a mean of a month's lows, not its coldest night. What that cell gave over 44 years: absolute minimum 19.9 °C, 1st-percentile night 21.2 °C, 99th-percentile day 27.7 °C.

How this section is made
Each figure is the median across the 8 grid cells holding the 10 in-range records, with the 10th–90th percentile span across those cells after the slash where it differs. A dash is a month one or more of those cells has no figure for in the grid (a variable CHELSA does not carry there), so no median is taken rather than one over fewer cells. Extremes and elevation were read at a typical spot in the range, cell 1797:3731 (0.125, 6.575). Normals: CHELSA V2.1 1981–2010 climatology, 0.05° cells (each the mean of ~36 1 km pixels). Across the range: median and 10th–90th percentile of each month across the 8 distinct grid cells holding 10 of the 10 in-range records; extremes and elevation at the typical cell 1797:3731 (its coldest month's mean nightly low nearest the median across cells, though its NASA POWER cell is only 8% land and none of the 0 next candidates within 2 °C of the median was mostly land); its position is the cell centre. Extremes: NASA POWER (MERRA-2) daily 1981–2024, cell 0.00_6.875, lapse-corrected +168 m at 6.5 °C/km. Elevation: ETOPO 2022, 194 m (cell mean).

Evidence usedThe map marker rests on all 176 georeferenced records inside the native range; the climate across the range on the 10 of them placed to within 10 km; the map shows only the 153 openly licensed ones, which alone would put the marker 9 km away. Under a dozen records behind the climate. 166 in-range records are placed to worse than 10 km, or with no stated accuracy (admitted only as a person's observation to three decimals), and stay on the map but off the climate.
How this section is made
The map marker: the openly licensed record nearest the middle of the densest 1° population of the 176 in-range records; it decides nothing. Records outside the native range, living specimens and records marked introduced are not used; which records count.

Every source is recorded as having answered, reported nothing, refused, failed, not been asked, or answered twice where one answer is taken (“not taken: two items answered”), and, for a source asked when this page was built, when: the figures are as the source held them that day; a source read from a file (Kew's World Checklist, a GBIF download) says "as of" the file's day instead; a row carried from an earlier build of the page names that build instead. Only “nothing to report” is ever shown as an absence. Records came from 19 datasets via GBIF.org; each carries its own licence.
