The phenology and ecology of flowers, fruits and mechanism of fruit dehiscence have been studied. Usher Calotropis procera produces flowers throughout the year with a peak in the early dry season (summer). The number of flowers was very high reaching of 959 flowers/tree, while the production of fruits was very low (22 fruit/tree). Each seed is covered at one tapered end by parachute-like silky hairs of about 3.16 ±0.4 cm. in length. It is possible to use the seed hairs as source for natural fibers in arid and semiarid regions. Fruits are dehiscent by gas pressure (140.75±24.4 mm Hg). It was found that the gas occupies about 70% of whole volume of fruit. The gas content (N2 & O2) expands with increased temperature causing a pressure on the pericarp and leading to fruit dehiscence.
