Summary
Brassia keiliana is a species of orchid. It is native to Colombia, Venezuela and Guyana.
Quoted from Wikipedia, "Brassia keiliana", CC BY-SA 4.0.
Cultivation
Grouped as an orchid, listed under the genus Brassia in the archetype table, and Kew describes it as “pseudobulbous epiphyte”.
Seasons
The rain rule reads a sharp season: 70% of the median year's rain (1,441 mm of 1,937 mm) falls in May to October. The temperature curve is flat, 1.4 °C between the warmest and coldest month, so the growing-season rule does not infer a growing season from it. Months are the habitat's, northern hemisphere. The temperature curve moves under 4 °C between the warmest and coldest month, where the shift rule does not apply, so they are not shifted for a collection elsewhere.
Rain
1,937 mm in the median year at the habitat, 1,441 mm of it May to October. Wettest month May at 286 mm, driest month January at 19 mm. Across the grid cells of the range the year's total runs 1,314 mm to 2,588 mm, the 10th to 90th percentile of each cell's own year. The median of the cells' own yearly totals, 2,201 mm, is the year's rain at the top of the page; the 1,937 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: 28 to 38 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 27, the highest 90th-percentile month 40).
Warmth and air
Monthly means: the coldest month's mean nightly low 14.8 °C in January (across the grid cells of the range 12.4 °C to 22.9 °C), the warmest month's mean daily high 20.5 °C in February (median year across the grid cells of the range, CHELSA). Cold floor: none read. The nearest figure is 14.8 °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 whose ground is too far above or below the typical spot to correct for, and are not used.
Relative humidity at the habitat: 63 to 66% 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 Brassia in the archetype table, and Kew describes it as “pseudobulbous 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 3 records in 3 grid cells; a page says so under 12 records or 5 cells, and shows the figures as read.
Habitat months, northern hemisphere
Mean daily high from 20 °C in Jan, Mar, Apr, May, Jun, Jul, Aug, Sep, Oct, Nov and Dec to 21 °C in Feb; mean nightly low from 15 °C in Jan, Feb and Dec to 16 °C in Mar, Apr, May, Jun, Jul, Aug, Sep, Oct and Nov. The cold quarter, Dec to Feb, is the three months around the coldest month's mean nightly low, centred on the 3 months in a row that tie for it. 1,937 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 3 habitat cells. Beneath: daily light integral and relative humidity through the year, each on its own scale.

The daily extremes were not used: the correction for elevation, +1305 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 11.7 °C, 1st-percentile night 13.8 °C.
