Ericameria cuneata McClatchie

The rain rule reads a winter growing season: 70% of the median year's rain (215 mm of 298 mm) falls in November to March, cooler than the year (wet-season mean 7.2 °C against a yearly mean of 14.2 °C). Months are the habitat's, northern hemisphere; shifted six months for a southern-hemisphere collection: May to September.

298 mm in the median year at the habitat, 215 mm of it November to March. Wettest month February at 52 mm, driest month June at 3 mm; 1 month under 5 mm. Across the grid cells of the range the year's total runs 141 mm to 957 mm, the 10th to 90th percentile of each cell's own year. The median of the cells' own yearly totals, 350 mm, is the year's rain at the top of the page; the 298 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.

Open sky over the habitat: 19 to 55 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 16, the highest 90th-percentile month 56).

Coldest: the 1st-percentile night over 44 years at a typical spot in the range is -6.2 °C, the absolute minimum -10.1 °C, 3,618 frost nights in 44 years, 82.2 a year (NASA POWER daily minima). Warmest: the 99th-percentile day is 34.0 °C. Monthly means: the coldest month's mean nightly low 0.4 °C in January and December (across the grid cells of the range -6.3 °C to 3.9 °C), the warmest month's mean daily high 31.4 °C in July (median year across the grid cells of the range, CHELSA). Cold floor: -6.2 °C, which is the 1st-percentile night over 44 years at a typical spot in the range (NASA POWER).

Relative humidity at the habitat: 39 to 49% 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.
