Astrophytum in numbers
17 datasets retaining the sample, conditions and source.
Mean site elevation describes the dataset analysed. Germination depends on material and experimental conditions. Laboratory test temperatures are not cultivation recommendations.

| Four Astrophytum speciesClimate projection periods | Reference period 1950–2000. The 2020 period covers 2010–2039, and the 2050 period covers 2040–2069.

| A. myriostigma · A. ornatumVapour uptake through the stem surface | About 10 times greater vapour uptake through hairy surfaces. Vapour 40–41°C, liquid 29–31.5°C. | Surfaces with and without hairs Trials with labelled water, sealed roots and a saturated atmosphere. | Result dependent on laboratory conditions, without determining a field dew balance. | [Lux and Kopunec 1992] |
| A. capricorneSeed buoyancy after 30 days | 40% of seeds with the layer of funicular remains intact, 70% after its removal. | 5 replicates of 10 seeds per treatment Material from 35 mother plants of the species. | This is not a test of adult root tolerance of flooding. | [Sánchez-Salas et al. 2012] |
| A. ornatumSeed buoyancy after 30 days | 90% of seeds with the layer of funicular remains intact, 100% after its removal. | 5 replicates of 10 seeds per treatment Material from 35 mother plants of the species. | The difference between treatments had p=0.055. It is not significant at a 0.05 threshold. | [Sánchez-Salas et al. 2012] |
| A. ornatumGermination | Below 30% in all treatments. Under submergence or a water layer, below 5%. | 5 replicates of 20 seeds per treatment Conditions of the 2012 experiment. | It does not determine the species' maximum attainable germination capacity. | [Sánchez-Salas et al. 2012] |
| A. myriostigma subsp. quadricostatumNumber of ribs | 4 ribs in 25% · 5 ribs in 75% | Jaumave, 28 plants Field sample in the 2019 paper. | Rib proportions alone do not diagnose provenance of horticultural plants. | [Montanucci and Kleszewski 2019] |

| A. myriostigma subsp. quadricostatumNumber of ribs | 4 ribs in 24% · 5 ribs in 40% · 6 ribs in 20% · 7 ribs in 16% | Los Ébanos, 25 plants Field sample in the 2019 paper. | Rib proportions alone do not diagnose provenance of horticultural plants. | [Montanucci and Kleszewski 2019] |
| A. coahuilenseNumber of ribs | 5 ribs in 222 plants, 6 ribs in 4 | 226 plants Material described in the 2024 paper. | The result refers to the material described. | [Montanucci 2024] |
| A. coahuilenseColoured flower throat | Coloured throat in 23 z 26 plants | 26 plants Material described in the 2024 paper. | Exceptions with entirely yellow flowers exist. | [Montanucci 2024] |
| A. coahuilenseSite exposure | 79.8% open sites and 20.2% partly sheltered | 114 plants Field sample in the 2024 paper. | It is not an instruction for maximum sunlight for every potted plant. | [Montanucci 2024] |
