Polystichum orbiculatum (Desv.) Gay

The rain rule reads no short rainy season: 70% of the median year's rain (1,683 mm of 2,212 mm) takes 8 months, October to May. Mean temperature moves 0.9 °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.

2,212 mm in the median year at the habitat, 1,683 mm of it October to May. Wettest month April at 263 mm, driest months (2 at 114 mm). Across the grid cells of the range the year's total runs 1,568 mm to 3,828 mm, the 10th to 90th percentile of each cell's own year. The median of the cells' own yearly totals, 2,197 mm, is the year's rain at the top of the page; the 2,212 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.

Open sky over the habitat: 26 to 33 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 37).

Monthly means: the coldest month's mean nightly low 3.2 °C in July (across the grid cells of the range -2.4 °C to 8.2 °C), the warmest month's mean daily high 12.1 °C in September and October (median year across the grid cells of the range, CHELSA). Cold floor: none read. The nearest figure is 3.2 °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.

Relative humidity at the habitat: 65 to 69% 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.
