Summary

Begonia fischeri, commonly called Fischer's begonia, is a species of flowering plant in the family Begoniaceae, native to Mexico, Central America and much of South America. It is a hardy perennial herb with a shrub-like growth habit.

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 “subshrub or shrub”, “seasonally dry tropical”.

Seasons

The rain rule reads no short rainy season: 70% of the median year's rain (1,596 mm of 2,130 mm) takes 8 months, October to May. Mean temperature moves 4.4 °C between the warmest and coldest month. Months are the habitat's, southern hemisphere; shifted six months for a northern-hemisphere collection: April to November.

Rain

2,130 mm in the median year at the habitat, 1,596 mm of it October to May. Wettest month March at 217 mm, driest month August at 105 mm. Across the grid cells of the range the year's total runs 1,549 mm to 4,408 mm, the 10th to 90th percentile of each cell's own year. The median of the cells' own yearly totals, 2,304 mm, is the year's rain at the top of the page; the 2,130 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: 23 to 33 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 17, the highest 90th-percentile month 37).

Warmth and air
Temperature

Coldest: the 1st-percentile night over 44 years at a typical spot in the range is 6.8 °C, the absolute minimum 2.0 °C, no frost in 44 years (NASA POWER daily minima). Warmest: the 99th-percentile day is 33.5 °C. Monthly means: the coldest month's mean nightly low 13.1 °C in July (across the grid cells of the range 9.6 °C to 19.2 °C), the warmest month's mean daily high 24.9 °C in February (median year across the grid cells of the range, CHELSA). Cold floor: 6.8 °C, which is the 1st-percentile night over 44 years at a typical spot in the range (NASA POWER).

Humidity

Relative humidity at the habitat: 65 to 68% 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 -4 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.

Group. Listed under the genus Begonia in the archetype table, and Kew describes it as “subshrub or shrub”, “seasonally dry 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.

Records on both sides of the equator: the 50 cells at least 10° north of it have seasons six months apart and are left out, not combined into a year no place has. These figures are across the 298 cells that remain: the 124 at least 10° south and the 174 within 10° of the equator, which stay in either way.

How this section is made
Each figure is the median across the 298 grid cells holding the 369 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 2336:2623 (-26.825, -48.825). Over 44 years there: absolute minimum 2.0 °C, 1st-percentile night 6.8 °C, 99th-percentile day 33.5 °C. 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 298 distinct grid cells holding 369 of the 436 in-range records on the southern side of the equator (50 cells poleward of 10° north, 124 poleward of 10° south: the two sides' seasons are not combined, and cells within 10° of the equator stay in); extremes and elevation at the typical cell 2336:2623 (its coldest month's mean nightly low nearest the median across cells); its position is the cell centre. Extremes: NASA POWER (MERRA-2) daily 1981–2024, cell -27.00_-48.750, lapse-corrected -4 m at 6.5 °C/km. Elevation: ETOPO 2022, 82 m (cell mean).

Evidence usedThe map marker rests on all 1175 georeferenced records inside the native range; the climate across the range on the 369 of them in the land cells it reads, of 436 placed to within 10 km; the map shows only the 867 openly licensed ones, which alone would put the marker 69 km away. 7 records outside the WCVP native range not used. 739 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 inside the densest 2° block of the 1175 in-range records; it decides nothing. Records outside the native range, living specimens and records marked introduced are not used; which records count.
