Summary

Melaleuca paludicola, commonly known as river bottlebrush, is a plant in the myrtle family Myrtaceae, and is endemic to eastern Australia. (Some Australian state herbaria continue to use the names Callistemon sieberi or Callistemon paludosus.) It is a shrub or small tree with flexible, often drooping branches, pinkish new growth and spikes of cream, pale yellow, or sometimes pink flowers in summer.

About the genus · Melaleuca

Melaleuca is a genus of nearly 300 species of plants in the myrtle family, Myrtaceae, commonly known as paperbarks, honey-myrtles, bottlebrushes or tea-trees. They range in size from small shrubs that rarely grow to more than 1 m high, to trees up to 35 m (115 ft). Their flowers generally occur in groups, forming a "head" or "spike" resembling a brush used for cleaning bottles, containing up to 80 individual flowers.

Cultivation

Seasons

The rain rule reads no short rainy season: 70% of the median year's rain (501 mm of 705 mm) takes 8 months, February and June to December. Mean temperature moves 12.3 °C between the warmest and coldest month. Months are the habitat's, southern hemisphere; shifted six months for a northern-hemisphere collection: December to June and August.

Rain

705 mm in the median year at the habitat, 501 mm of it February and June to December. Wettest month November at 73 mm, driest month April at 47 mm. Across the grid cells of the range the year's total runs 562 mm to 1,013 mm, the 10th to 90th percentile of each cell's own year. The median of the cells' own yearly totals, 731 mm, is the year's rain at the top of the page; the 705 mm here is the median year's, the twelve monthly medians added, which the rain rule reads. Habitat calendar, southern hemisphere; median year across the grid cells of the range, CHELSA.

Light

Open sky over the habitat: 14 to 46 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 12, the highest 90th-percentile month 49).

Warmth and air
Temperature

Coldest: the 1st-percentile night over 44 years at a typical spot in the range is -0.6 °C, the absolute minimum -3.8 °C, 295 frost nights in 44 years, 6.7 a year (NASA POWER daily minima). Warmest: the 99th-percentile day is 40.3 °C. Monthly means: the coldest month's mean nightly low 3.7 °C in July (across the grid cells of the range 1.2 °C to 6.5 °C), the warmest month's mean daily high 25.7 °C in January (median year across the grid cells of the range, CHELSA). Cold floor: -0.6 °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: 56 to 63% 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 -5 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 884 grid cells holding the 1680 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 2513:6540 (-35.675, 147.025). Over 44 years there: absolute minimum -3.8 °C, 1st-percentile night -0.6 °C, 99th-percentile day 40.3 °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 884 distinct grid cells holding 1680 of the 1680 in-range records; extremes and elevation at the typical cell 2513:6540 (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 -35.50_146.875, lapse-corrected -5 m at 6.5 °C/km. Elevation: ETOPO 2022, 213 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 keys of the names Kew's World Checklist holds as this plant: 3173381 (Callistemon sieberi DC., 2000 records), 3173383 (Callistemon salignus var. sieberi (DC.) F.Muell., 0 records), 5415481 (Melaleuca paludicola Craven, 280 records), 6306468 (Callistemon salignus f. sieberi (DC.) Voss, 0 records).

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 33 datasets via GBIF.org; each carries its own licence.
