Summary

Myosotis capitata is a species of flowering plant in the family Boraginaceae, endemic to the Campbell and Auckland Islands of New Zealand. Joseph Dalton Hooker described the species in his 19th century work Flora Antarctica. Plants of this species of forget-me-not are perennial and erect, and have ebracteate inflorescences and blue corollas. It is one of two native species of Myosotis in the New Zealand subantarctic islands, the other being M. antarctica, which can also have blue corollas.

About the genus · Myosotis

Myosotis is a genus of flowering plants in the borage family Boraginaceae. In the Northern Hemisphere, they are colloquially known as forget-me-nots or scorpion grasses. The forget-me-not is the official flower of Alaska.

Cultivation

Seasons

The rain rule reads no short rainy season: 70% of the median year's rain (1,004 mm of 1,293 mm) takes 9 months, December to January, March to June and August to October. Mean temperature moves 3.3 °C between the warmest and coldest month. Months are the habitat's, southern hemisphere. The temperature curve moves under 4 °C between the warmest and coldest month, where the shift rule does not apply, so they are not shifted for a collection elsewhere.

Rain

1,293 mm in the median year at the habitat, 1,004 mm of it December to January, March to June and August to October. Wettest month January at 128 mm, driest month July at 95 mm. Across the grid cells of the range the year's total runs 1,159 mm to 1,387 mm, the 10th to 90th percentile of each cell's own year. The median of the cells' own yearly totals, 1,296 mm, is the year's rain at the top of the page; the 1,293 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: 4 to 38 mol/m²/day across the year (daily light integral, median year across the grid cells of the range, CHELSA).

Warmth and air
Temperature

Monthly means: the coldest month's mean nightly low 5.2 °C in July, August and September (across the grid cells of the range 4.6 °C to 5.9 °C), the warmest month's mean daily high 10.4 °C in February (median year across the grid cells of the range, CHELSA). Cold floor: none read. The nearest figure is 5.2 °C, the coldest month's mean nightly low, July, August and September, 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 that is mostly sea and are not used.

Humidity

Relative humidity at the habitat: 65 to 69% 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 read at a NASA POWER cell that is 20% land: neither it nor the next candidates whose coldest month's mean nightly low is within 2 °C of the median across cells sit in a POWER cell that is mostly land, and the rule reads a cold floor only from a cell that is mostly land, so none is read for this species. Nor is the coldest month's mean nightly low taken as one: it is a mean of a month's lows, not its coldest night. What that cell gave over 44 years: absolute minimum -1.8 °C, 1st-percentile night 1.3 °C, 99th-percentile day 11.9 °C.

How this section is made
Each figure is the median across the 19 grid cells holding the 29 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 2813:6921 (-50.675, 166.075). 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 19 distinct grid cells holding 29 of the 29 in-range records; extremes and elevation at the typical cell 2813:6921 (its coldest month's mean nightly low nearest the median across cells, though its NASA POWER cell is only 20% land and none of the 11 next candidates within 2 °C of the median was mostly land); its position is the cell centre. Extremes: NASA POWER (MERRA-2) daily 1981–2024, cell -50.50_166.250, lapse-corrected +202 m at 6.5 °C/km. Elevation: ETOPO 2022, 224 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.

Evidence usedThe map marker rests on all 70 georeferenced records inside the native range; the climate across the range on the 29 of them placed to within 10 km; the map shows only the 61 openly licensed ones, which alone would put the marker 1 km away. 1 record outside the WCVP native range not used. 41 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 of the 70 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 5 datasets via GBIF.org; each carries its own licence.
