About the genus · Aristolochia

Aristolochia is a large plant genus with over 500 species that is the type genus of the family Aristolochiaceae. Its members are commonly known as birthwort, pipevine or Dutchman's pipe and are widespread and occur in diverse climates. Some species, like A. utriformis and A. westlandii, are threatened with extinction.

Cultivation

Seasons

The rain rule reads a summer growing season: 70% of the median year's rain (1,235 mm of 1,669 mm) falls in May to September, warmer than the year (wet-season mean 18.6 °C against a yearly mean of 8.9 °C). Months are the habitat's, northern hemisphere; shifted six months for a southern-hemisphere collection: November to March.

Rain

1,669 mm in the median year at the habitat, 1,235 mm of it May to September. Wettest month July at 349 mm, driest month December at 32 mm. Across the grid cells of the range the year's total runs 1,294 mm to 2,041 mm, the 10th to 90th percentile of each cell's own year. The median of the cells' own yearly totals, 1,688 mm, is the year's rain at the top of the page; the 1,669 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: 16 to 37 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 14, the highest 90th-percentile month 38).

Warmth and air
Temperature

Coldest: the 1st-percentile night over 44 years at a typical spot in the range is -20.4 °C, the absolute minimum -28.1 °C, 6,964 frost nights in 44 years, 158.3 a year (NASA POWER daily minima). Warmest: the 99th-percentile day is 28.2 °C. Monthly means: the coldest month's mean nightly low -12.4 °C in January (across the grid cells of the range -15.0 °C to -5.7 °C), the warmest month's mean daily high 24.5 °C in August (median year across the grid cells of the range, CHELSA). Cold floor: -20.4 °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: 54 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 +274 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.

How this section is made
Each figure is the median across the 150 grid cells holding the 339 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 1048:6176 (37.575, 128.825). Over 44 years there: absolute minimum -28.1 °C, 1st-percentile night -20.4 °C, 99th-percentile day 28.2 °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 150 distinct grid cells holding 339 of the 339 in-range records; extremes and elevation at the typical cell 1048:6176 (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 37.50_128.750, lapse-corrected +274 m at 6.5 °C/km. Elevation: ETOPO 2022, 804 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 the cells of the in-range records placed well enough to read one, not at the marker.
Openly licensed records inside the range, framed on where they fall.
NativePrimorye, China South-Central, Manchuria, China North-Central, China Southeast, Korea · regions are the level-3 units of the World Geographical Scheme for Recording Plant Distributions, as Kew's World Checklist records ranges, some under historical names such as Yugoslavia or Czechoslovakia (how).

Evidence usedThe map marker rests on all 399 georeferenced records inside the native range; the climate across the range on the 339 of them placed to within 10 km; the map shows only the 46 openly licensed ones, which alone would put the marker 9 km away. 1 record outside the WCVP native range not used. 60 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.

Only “nothing to report” is ever shown as an absence. Records came from 33 datasets via GBIF.org; each carries its own licence.
