About the genus · Cochemiea
Cochemiea is a genus of cactus. The group was previously synonymized with Mammillaria, until molecular phylogenetic studies determined that—when broadly circumscribed—Mammillaria is not monophyletic; thus, Cochemiea has been accepted as a distinct genus.

Cultivation
Grouped as a cactus or succulent, listed under the family Cactaceae in the archetype table, and Kew describes it as “succulent subshrub”.
Seasons
Rain at the habitat is 114 mm in the median year (across the grid cells of the range, CHELSA). Under 120 mm the rain rule reads no rainy season, and the growing-season rule infers nothing from it. The temperature rule reads the cooler six months as November to April. Months are the habitat's, northern hemisphere; shifted six months for a southern-hemisphere collection: May to October.
Rain
114 mm in the median year at the habitat. Wettest month September at 32 mm, driest months (2 at 0 mm); 4 months under 5 mm. Across the grid cells of the range the year's total runs 113 mm to 116 mm, the 10th to 90th percentile of each cell's own year. The median of the cells' own yearly totals, 115 mm, is the year's rain at the top of the page; the 114 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: 24 to 53 mol/m²/day across the year (daily light integral, median year across the grid cells of the range, CHELSA).
Warmth and air
Monthly means: the coldest month's mean nightly low 15.4 °C in January and February (across the grid cells of the range 12.1 °C to 15.8 °C), the warmest month's mean daily high 30.4 °C in August (median year across the grid cells of the range, CHELSA). Cold floor: none read. The nearest figure is 15.4 °C, the coldest month's mean nightly low, January and February, 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.
Relative humidity at the habitat: 50 to 62% 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.
Group. Listed under the family Cactaceae in the archetype table, and Kew describes it as “succulent subshrub”. A group is taken only where Kew's description of the species agrees with the table's listing. The table gives no figure and no prose; the cold floor is the habitat's alone.
Climate across the habitat
Habitat months, northern hemisphere
Mean daily high from 17 °C in Jan and Feb to 30 °C in Jul, Aug and Sep; mean nightly low from 15 °C in Jan and Feb to 28 °C in Aug. The cold quarter, Dec to Feb, is the three months around the coldest month's mean nightly low, centred on the 2 months in a row that tie for it. 114 mm of rain in the median year (the twelve monthly medians added), the wettest month Sep. The bands show the 10th to 90th percentile across 5 habitat cells. Beneath: daily light integral and relative humidity through the year, each on its own scale.

The daily extremes were read at a NASA POWER cell that is 4% 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 4.5 °C, 1st-percentile night 11.8 °C, 99th-percentile day 32.9 °C.
