Summary

Anacis tripteris is a North American species of flowering plant in the family Asteraceae. It is widespread across much of eastern and central North America from the Florida Panhandle west as far as eastern Texas and north to Québec and Ontario. Its common names include tall tickseed, tall coreopsis, and Atlantic coreopsis.

Habitat rain 1059 mm a year, wettest May at 115 mm, driest February at 59 mm (habitat calendar, northern hemisphere). Open sky over the habitat: 11 to 41 mol/m²/day. Cold floor -19.3 °C (1st-percentile habitat night, NASA POWER).

Each sentence is one card's own one-line form, written by the same rule as the card (Its year, Rain, Light, Temperature); the note cannot say what a card does not. Months are given for the northern hemisphere (set your site in Settings to change this), and the habitat's own alongside. The cards · the figures.

Cultivation

Its year Rain rule: no season, 70% of the rain takes 8 months (April to November in the northern hemisphere).

This species’ habitat figures, and what two fixed rules read from them.

The rain rule reads no season: 70% of the year's rain (794 mm of 1059 mm) takes 8 months, April to November. Mean temperature moves 26.8 °C between the warmest and coldest month. Months are the habitat's, northern hemisphere; shifted six months for a southern-hemisphere collection: October to May.

Read from the median year of CHELSA monthly rainfall and mean temperature across the envelope cells: 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 gives a season to reverse. A reading of the curves, not an observation of the plant.

1059 mm a year at the habitat, 794 mm of it April to November. Wettest month May at 115 mm, driest February at 59 mm. Across the envelope cells the year's total runs 929 mm to 1425 mm (10th to 90th percentile of each cell's own year) (median year across the envelope cells, CHELSA; habitat calendar, northern hemisphere).

Open sky over the habitat: 11 to 41 mol/m²/day across the year (daily light integral, median year across the envelope cells, CHELSA; the lowest 10th-percentile month across the cells is 10, the highest 90th-percentile month 42).

Temperature

Coldest: the 1st-percentile night over 44 years at the typical cell is -19.3 °C, the absolute minimum -34.9 °C, about 126 frost nights a year (NASA POWER daily minima). Warmest: the 99th-percentile day is 34.5 °C. Monthly means: coldest night -6.5 °C in January (across the envelope cells -9.9 °C to 0.9 °C), warmest day 28.6 °C in July (median year across the envelope cells, CHELSA). Cold floor: -19.3 °C, which is the 1st-percentile night over 44 years at the typical cell (NASA POWER).
