About the genus · Prosthechea
Prosthechea is a genus of flowering plants in the orchid family (Orchidaceae). The name is derived from the Greek word prostheke (appendix), referring to the appendage on the back of the column. Appendage orchid is a common name for this genus. More on Wikipedia ›

Cultivation
Seasons
The rain rule reads a summer growing season: 70% of the median year's rain (1,366 mm of 1,716 mm) falls in June to October, warmer than the year (wet-season mean 16.0 °C against a yearly mean of 15.1 °C). Months are the habitat's, northern hemisphere; shifted six months for a southern-hemisphere collection: December to April.
Rain
1,716 mm in the median year at the habitat, 1,366 mm of it June to October. Wettest month June at 320 mm, driest month February at 23 mm. Across the grid cells of the range the year's total runs 1,086 mm to 3,433 mm, the 10th to 90th percentile of each cell's own year. The median of the cells' own yearly totals, 1,742 mm, is the year's rain at the top of the page; the 1,716 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: 30 to 43 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 24, the highest 90th-percentile month 46).
Warmth and air
Monthly means: the coldest month's mean nightly low 7.3 °C in January (across the grid cells of the range 3.9 °C to 12.1 °C), the warmest month's mean daily high 22.6 °C in April (median year across the grid cells of the range, CHELSA). Cold floor: none read. The nearest figure is 7.3 °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: 57 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.
Climate across the habitat
Habitat months, northern hemisphere
Mean daily high from 18 °C in Jan, Nov and Dec to 23 °C in Apr; mean nightly low from 7 °C in Jan to 12 °C in May, Jun, Jul, Aug and Sep. The cold quarter, Dec to Feb, is the three months around the coldest month's mean nightly low. 1,716 mm of rain in the median year (the twelve monthly medians added), the wettest month Jun. The bands show the 10th to 90th percentile across 171 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, +1289 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 -2.9 °C, 1st-percentile night 3.1 °C.
