Summary

Viburnum recognitum, variously called the northern arrowwood, southern arrowwood, and smooth arrow-wood, is a species of flowering plant in the family Viburnaceae. It is native to eastern Canada, and the central and eastern United States. A shrub or small shrubby tree, they are typically found in wetter habitats such as stream banks, bottomlands, swamps, and mesic woodlands. It is closely related to, and may be a subtaxon of, Viburnum dentatum, the southern arrowwood or roughish arrowwood.

Rain rule: no season, 70% of the rain takes 8 months (March to October in the northern hemisphere). Habitat rain 1205 mm a year, wettest July at 114 mm, driest February at 78 mm (habitat calendar, northern hemisphere). Open sky over the habitat: 11 to 39 mol/m²/day. Cold floor -14.3 °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 (March to October 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 (846 mm of 1205 mm) takes 8 months, March to October. Mean temperature moves 25.1 °C between the warmest and coldest month. Months are the habitat's, northern hemisphere; shifted six months for a southern-hemisphere collection: September to April.

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.

1205 mm a year at the habitat, 846 mm of it March to October. Wettest month July at 114 mm, driest February at 78 mm. Across the envelope cells the year's total runs 1001 mm to 1395 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 39 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 9, the highest 90th-percentile month 41).

Temperature

Coldest: the 1st-percentile night over 44 years at the typical cell is -14.3 °C, the absolute minimum -23.3 °C, about 119 frost nights a year (NASA POWER daily minima). Warmest: the 99th-percentile day is 30.0 °C. Monthly means: coldest night -6.5 °C in January (across the envelope cells -11.5 °C to -2.2 °C), warmest day 27.2 °C in July (median year across the envelope cells, CHELSA). Cold floor: -14.3 °C, which is the 1st-percentile night over 44 years at the typical cell (NASA POWER).

Each figure is the median across the 1384 grid cells holding the 1687 in-range records, with the 10th–90th percentile span across those cells after the slash where it differs. Extremes and elevation were read at the typical cell 942:2016 (42.875, -79.175). Over 44 years there: absolute minimum -23.3 °C, 1st-percentile night -14.3 °C, 99th-percentile day 30.0 °C.

Evidence usedThe map marker and the climate envelope rest on all 1835 georeferenced records inside the native range; the map shows only the 603 openly licensed ones, which alone would put the marker 13 km away. 10 records outside the range (gardens, roadsides, misidentifications) ignored. 148 in-range records are placed to worse than 10 km and stay on the map but off the climate.
