Summary

Berberis napaulensis (syn. B. duclouxiana; Nepali: जमाने मान्द्रो, Chinese: 尼泊尔十大功劳) is a shrub in the family Berberidaceae described as a species in 1821. It is native to the Himalayas (northwestern India, Nepal, Bhutan, Sikkim, Assam), and into the mountains of southwestern China (Tibet, Yunnan, Guangxi, and Sichuan), Myanmar, Thailand, and Vietnam, growing at altitudes of 1,200-3,000 metres. This species is used medicinally throughout the Sikkim Eastern Himalayas.

About the genus · Berberis

Berberis, commonly known as barberry, is a large genus of deciduous and evergreen shrubs from 1–5 m tall, found throughout temperate and subtropical regions of the world. Species diversity is greatest in South America and Asia, but native species also appear in Europe, Africa, and North America.

Cultivation

Seasons

The rain rule reads a summer growing season: 70% of the median year's rain (2,129 mm of 2,723 mm) falls in June to September, warmer than the year (wet-season mean 17.3 °C against a yearly mean of 12.2 °C). Months are the habitat's, northern hemisphere; shifted six months for a southern-hemisphere collection: December to March.

Rain

2,723 mm in the median year at the habitat, 2,129 mm of it June to September. Wettest month July at 716 mm, driest month December at 19 mm. Across the grid cells of the range the year's total runs 1,437 mm to 4,040 mm, the 10th to 90th percentile of each cell's own year. The median of the cells' own yearly totals, 2,800 mm, is the year's rain at the top of the page; the 2,723 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: 23 to 41 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 18, the highest 90th-percentile month 44).

Warmth and air
Temperature

Monthly means: the coldest month's mean nightly low -0.5 °C in January (across the grid cells of the range -6.6 °C to 4.6 °C), the warmest month's mean daily high 20.0 °C in June (median year across the grid cells of the range, CHELSA). Cold floor: none read. The nearest figure is -0.5 °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.

Humidity

Relative humidity at the habitat: 56 to 75% 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.

The daily extremes were not used: the correction for elevation, -1113 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 -10.5 °C, 1st-percentile night -1.1 °C.

How this section is made
Each figure is the median across the 83 grid cells holding the 114 in-range records, with the 10th–90th percentile span across those cells after the slash where it differs. A dash is a month one or more of those cells has no figure for in the grid (a variable CHELSA does not carry there), so no median is taken rather than one over fewer cells. Extremes and elevation were read at a typical spot in the range, cell 1232:5276 (28.375, 83.825). Normals: CHELSA V2.1 1981–2010 climatology, 0.05° cells (each the mean of ~36 1 km pixels). Across the range: median and 10th–90th percentile of each month across the 83 distinct grid cells holding 114 of the 114 in-range records; extremes and elevation at the typical cell 1232:5276 (its coldest month's mean nightly low nearest the median across cells); its position is the cell centre. Extremes: NASA POWER (MERRA-2) daily 1981–2024, cell 28.50_83.750, lapse-corrected -1113 m at 6.5 °C/km. Elevation: ETOPO 2022, 1929 m (cell mean).

Natural habitat

Native range as published by WCVP; the marker is where the records are densest and decides nothing: the climate was read across the cells of the in-range records placed well enough to read one, not at the marker.
Openly licensed records inside the range, framed on where they fall.

This species has no GBIF key of its own. Its records are GBIF's under the key of the name Kew's World Checklist holds as this plant: 3981498 (Mahonia napaulensis DC., 260 records). No name was matched to GBIF; the keys are read from Kew's synonymy. How.
