Temperature
Average annual temperature regimes vary approximately 13°C (55°F) for Pachypodium brevicaule, P. densiflorum, and P. eburneum to 26.7°C (81°F) for the species P. decaryi, P. rutenbergainum, and P. windsorii. In continental southern Africa, the extreme temperatures range from -10°C (14°F) for P. succulentum locations to as much as 45°C (113°F) for P. bispinosum, P. lealii, and P. namaquanum. In winter time, snow remains a possibility for Africa's south-eastern Mountain Grassland. Importantly the African species of Pachypodium live in habitats with a heat regime resembling greater amplitudes than those of Madagascar. There, in the central part where most species come from, frost occasionally occurs. One station there has recorded a temperature of -2.6°C (27°F) whereas another has recorded a low of -6.3°C (21°F). In the sub–arid regions of Madagascar, the maximum temperature recorded can climb up to 40°C (104°).

Famous quotes containing the word temperature:
“The siren south is well enough, but New York, at the beginning of March, is a hoyden we would not care to miss—a drafty wench, her temperature up and down, full of bold promises and dust in the eye.”
—E.B. (Elwyn Brooks)
“The bourgeois treasures nothing more highly than the self.... And so at the cost of intensity he achieves his own preservation and security. His harvest is a quiet mind which he prefers to being possessed by God, as he prefers comfort to pleasure, convenience to liberty, and a pleasant temperature to that deathly inner consuming fire.”
—Hermann Hesse (1877–1962)
“This pond never breaks up so soon as the others in this neighborhood, on account both of its greater depth and its having no stream passing through it to melt or wear away the ice.... It indicates better than any water hereabouts the absolute progress of the season, being least affected by transient changes of temperature. A severe cold of a few days’ duration in March may very much retard the opening of the former ponds, while the temperature of Walden increases almost uninterruptedly.”
—Henry David Thoreau (1817–1862)
