Summary

Eugenia rhombea, the red stopper, is a species of flowering plant in the family Myrtaceae. It is native to southern Florida, Mexico, Central America, the Caribbean, and northern Venezuela. A shrub or tree reaching 12 ft (3.7 m) with white flowers, it is typically found in rockland hammocks.

About the genus · Eugenia

Eugenia is a genus of flowering plants in the myrtle family Myrtaceae. It has a worldwide, although highly uneven, distribution in tropical and subtropical regions. The bulk of the approximately 1,100 species occur in the New World tropics, especially in the eastern Brazil's northern Andes, the Caribbean, and the Atlantic Forest. More on Wikipedia ›

Cultivation

Seasons

The rain rule reads a summer growing season: 70% of the median year's rain (966 mm of 1,281 mm) falls in May to October, warmer than the year (wet-season mean 26.8 °C against a yearly mean of 25.5 °C). Months are the habitat's, northern hemisphere; shifted six months for a southern-hemisphere collection: November to April.

Rain

1,281 mm in the median year at the habitat, 966 mm of it May to October. Wettest month September at 211 mm, driest month February at 41 mm. Across the grid cells of the range the year's total runs 1,032 mm to 1,961 mm, the 10th to 90th percentile of each cell's own year. The median of the cells' own yearly totals, 1,246 mm, is the year's rain at the top of the page; the 1,281 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: 26 to 42 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 44).

Warmth and air
Temperature

Coldest: the 1st-percentile night over 44 years at a typical spot in the range is 14.9 °C, the absolute minimum 10.1 °C, no frost in 44 years (NASA POWER daily minima). Warmest: the 99th-percentile day is 36.7 °C. Monthly means: the coldest month's mean nightly low 19.8 °C in January (across the grid cells of the range 14.7 °C to 24.1 °C), the warmest month's mean daily high 29.0 °C in May, July and August (median year across the grid cells of the range, CHELSA). Cold floor: 14.9 °C, which is the 1st-percentile night over 44 years at a typical spot in the range (NASA POWER).

Humidity

Relative humidity at the habitat: 60 to 64% 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. NASA POWER daily minima and maxima over 44 years at a typical spot in the range, lapse-corrected -11 m to its elevation; CHELSA monthly means, median year across the grid cells of the range. The cold floor is the 1st-percentile night named in its sentence. Not a measured survival limit for any plant in a pot.

Humidity. CHELSA relative humidity, median year across the grid cells of the range.

How this section is made
Each figure is the median across the 121 grid cells on land that hold in-range records (149 records in those cells; 2 more cells hold records but no land by the elevation layer, so those records sit at sea and the cells are left out), 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 1407:1841 (19.625, -87.925). Over 44 years there: absolute minimum 10.1 °C, 1st-percentile night 14.9 °C, 99th-percentile day 36.7 °C. 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 121 distinct grid cells holding 149 of the 151 in-range records (2 further cells with records at sea, by the elevation layer, left out); extremes and elevation at the typical cell 1407:1841 (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 19.50_-88.125, lapse-corrected -11 m at 6.5 °C/km. Elevation: ETOPO 2022, 10 m (cell mean).

Evidence usedThe map marker rests on all 369 georeferenced records inside the native range; the climate across the range on the 149 of them in the land cells it reads, of 151 placed to within 10 km; the map shows only the 304 openly licensed ones, which alone would put the marker 2676 km away. 10 records outside the WCVP native range not used. 218 in-range records are placed to worse than 10 km, or with no stated accuracy (admitted only as a person's observation to three decimals), and stay on the map but off the climate.
How this section is made
The map marker: the openly licensed record nearest the middle of the densest 1° population inside the densest 4° block of the 369 in-range records; it decides nothing. Records outside the native range, living specimens and records marked introduced are not used; which records count.

Every source is recorded as having answered, reported nothing, refused, failed, not been asked, or answered twice where one answer is taken (“not taken: two items answered”), and, for a source asked when this page was built, when: the figures are as the source held them that day; a source read from a file (Kew's World Checklist, a GBIF download) says "as of" the file's day instead; a row carried from an earlier build of the page names that build instead. Only “nothing to report” is ever shown as an absence. Records came from 56 datasets via GBIF.org; each carries its own licence.
