Summary

Philodendron pastazanum is a species of flowering plant in the family Araceae. It is native to Ecuador and Peru. It has cordate leaves, somewhat similar to Philodendron mamei and Philodendron sodiroi, but with deep green foliage and light venation.

About the genus · Philodendron

Philodendron is a large genus of flowering plants in the family Araceae. As of September 2025, the Plants of the World Online accepted 625 species; other sources accept different numbers. Regardless of number of species, the genus is the second-largest member of the family Araceae, after genus Anthurium. More on Wikipedia ›

Cultivation

Grouped as a tropical foliage plant, listed under the genus Philodendron in the archetype table, and Kew describes it as “climber”, “wet tropical”.

Seasons

The rain rule reads no short rainy season: 70% of the median year's rain (3,155 mm of 4,388 mm) takes 8 months, March to July and October to December. Mean temperature moves 2.0 °C between the warmest and coldest month. 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

4,388 mm in the median year at the habitat, 3,155 mm of it March to July and October to December. Wettest month April at 455 mm, driest month August at 293 mm. Across the grid cells of the range the year's total runs 1,511 mm to 5,102 mm, the 10th to 90th percentile of each cell's own year. The median of the cells' own yearly totals, 4,532 mm, is the year's rain at the top of the page; the 4,388 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: 25 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 23, the highest 90th-percentile month 36).

Warmth and air
Temperature

Monthly means: the coldest month's mean nightly low 18.5 °C in July (across the grid cells of the range 16.2 °C to 19.9 °C), the warmest month's mean daily high 27.3 °C in October (median year across the grid cells of the range, CHELSA). Cold floor: none read. The nearest figure is 18.5 °C, the coldest month's mean nightly low, July, 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 whose ground is too far above or below the typical spot to correct for, and are not used.

Humidity

Relative humidity at the habitat: 64 to 67% 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 Philodendron in the archetype table, and Kew describes it as “climber”, “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.

The daily extremes were not used: the correction for elevation, -1861 m, is beyond the 1,000 m either way that a lapse rate is applied over, so the weather cell's ground is other terrain than the typical spot's. So no cold floor is read for this species, and the coldest month's mean nightly low is not taken as one. What that cell gave, so corrected, over 44 years: absolute minimum 14.6 °C, 1st-percentile night 18.1 °C.

How this section is made
Each figure is the median across the 39 grid cells holding the 64 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 1824:2042 (-1.225, -77.875). 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 39 distinct grid cells holding 64 of the 64 in-range records; extremes and elevation at the typical cell 1824:2042 (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 -1.00_-78.125, lapse-corrected -1861 m at 6.5 °C/km. Elevation: ETOPO 2022, 634 m (cell mean).

Evidence usedThe map marker rests on all 93 georeferenced records inside the native range; the climate across the range on the 64 of them placed to within 10 km; the map shows only the 37 openly licensed ones, which alone would put the marker 1 km away. 2 records outside the WCVP native range not used. 29 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 93 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 7 datasets via GBIF.org; each carries its own licence.
