Wet summers: the rain comes May to October (the habitat's months, not shifted), read as a summer growing season. rain rule, CHELSA
Not shifted: the shift rule does not apply to this habitat. The chart is in the habitat's months.

From few records: 7 records in 6 grid cells. The records.

Cultivation

Grouped as a fern or moss, listed under the family Dryopteridaceae in the archetype table, and Kew describes it as “perennial or rhizomatous geophyte”.

Seasons

The rain rule reads a summer growing season: 70% of the median year's rain (2,360 mm of 3,151 mm) falls in May to October, warmer than the year (wet-season mean 24.8 °C against a yearly mean of 22.6 °C). Months are the habitat's, southern 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

3,151 mm in the median year at the habitat, 2,360 mm of it May to October. Wettest month August at 485 mm, driest month December at 80 mm. Across the grid cells of the range the year's total runs 2,682 mm to 3,972 mm, the 10th to 90th percentile of each cell's own year. The median of the cells' own yearly totals, 3,037 mm, is the year's rain at the top of the page; the 3,151 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: 21 to 36 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 12, the highest 90th-percentile month 40).

Warmth and air
Temperature

Monthly means: the coldest month's mean nightly low 16.7 °C in January (across the grid cells of the range 10.2 °C to 22.3 °C), the warmest month's mean daily high 28.1 °C in July (median year across the grid cells of the range, CHELSA). Cold floor: none read. The nearest figure is 16.7 °C, the coldest month's mean nightly low, January, 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: 67 to 70% 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 family Dryopteridaceae in the archetype table, and Kew describes it as “perennial or rhizomatous geophyte”. 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 7 records in 6 grid cells; a page says so under 12 records or 5 cells, and shows the figures as read.

The daily extremes were read at a NASA POWER cell that is 24% 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 14.5 °C, 1st-percentile night 18.0 °C, 99th-percentile day 30.0 °C.

How this section is made
Each figure is the median across the 6 grid cells on land that hold in-range records (7 records in those cells; 1 more cell holds records but no land by the elevation layer, so those records sit at sea and the cell is left out), 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 1357:6017 (22.125, 120.875). 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 6 distinct grid cells holding 7 of the 8 in-range records (1 further cell with records at sea, by the elevation layer, left out); extremes and elevation at the typical cell 1357:6017 (its coldest month's mean nightly low nearest the median across cells, though its NASA POWER cell is only 24% 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 22.00_120.625, lapse-corrected +88 m at 6.5 °C/km. Elevation: ETOPO 2022, 112 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.

Evidence usedThe map marker rests on all 91 georeferenced records inside the native range; the climate across the range on the 7 of them in the land cells it reads, of 8 placed to within 10 km; the map shows only the 72 openly licensed ones, which alone would put the marker in the same place. 16 records outside the WCVP native range not used. Under a dozen records behind the climate. 83 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 4° block of the 91 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 21 datasets via GBIF.org; each carries its own licence.
