Euphorbia (Pedilanthus) tithymaloides
This ornamental plant is flowering for the first time in 5 years. It seemed that the flowers emerged from stalks that were stressed (shriveled) and occurred during a period of low rainfall. It is Euphorbia tithymaloides, a perennial succulent spurge, native to tropical and subtropical North America and Central America.
Planted as an ornamental hedgerow plant in a semi-urban environment of houses, yards & gardens and patches of remnant forest. This is in the equatorial tropics of northern New Guinea.
(I suffered failure of a disk drive that included better images of this spotting, and these are all I had left. Since I have not seen this plant ever flower (in 5 years!), I figured it was worth posting).
