Summary
Bulbophyllum ericssonii is a species of orchid in the genus Bulbophyllum that grows from Malesia to New Guinea.
Quoted from Wikipedia, "Bulbophyllum ericssonii", CC BY-SA 4.0.
Cultivation
Grouped as an orchid, listed under the genus Bulbophyllum in the archetype table, and Kew describes it as “pseudobulbous geophyte or epiphyte”.
Seasons
The rain rule reads no short rainy season: 70% of the median year's rain (2,752 mm of 3,910 mm) takes 8 months, September to January and April to June. Mean temperature moves 0.9 °C between the warmest and coldest month. 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
3,910 mm in the median year at the habitat, 2,752 mm of it September to January and April to June. Wettest month May at 358 mm, driest month February at 266 mm. Across the grid cells of the range the year's total runs 3,180 mm to 5,435 mm, the 10th to 90th percentile of each cell's own year. The median of the cells' own yearly totals, 3,892 mm, is the year's rain at the top of the page; the 3,910 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: 31 to 34 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 26, the highest 90th-percentile month 37).
Warmth and air
Coldest: the 1st-percentile night over 44 years at a typical spot in the range is 14.5 °C, the absolute minimum 12.6 °C, no frost in 44 years (NASA POWER daily minima). Warmest: the 99th-percentile day is 26.2 °C. Monthly means: the coldest month's mean nightly low 17.3 °C in August (across the grid cells of the range 16.9 °C to 19.3 °C), the warmest month's mean daily high 24.8 °C in May (median year across the grid cells of the range, CHELSA). Cold floor: 14.5 °C, which is the 1st-percentile night over 44 years at a typical spot in the range (NASA POWER).
Relative humidity at the habitat: 68 to 71% 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 +42 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 Bulbophyllum in the archetype table, and Kew describes it as “pseudobulbous geophyte or epiphyte”. 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 4 records in 4 grid cells; a page says so under 12 records or 5 cells, and shows the figures as read.
Habitat months, northern hemisphere
A flat year: mean daily high about 25 °C and mean nightly low about 17 °C in every month, so the cold quarter is shaded by rounding only. 3,910 mm of rain in the median year (the twelve monthly medians added), the wettest month May. The bands show the 10th to 90th percentile across 4 habitat cells. Over 44 years at a typical spot in the range (NASA POWER) the absolute minimum was 12.6 °C and the 99th-percentile day 26.2 °C; neither is dated to a month. Beneath: daily light integral and relative humidity through the year, each on its own scale.
