Dimerias in juvenile stage
The Dimerias are primarily C4 grasses, which exclusively prefer the natural tropical climate. Dimerias enjoy monsoon climate in general, and are localized along the Tropical wet region.
The sprouting, flowering and fruit-setting of annual species occur within a period of 4 months. In lateritic plains (Western Ghats), the Dimerias usually sprouts during October and completely dry out by the end of February. The seeds that fall and deposited in the crevices of laterite remains there for almost 10 months and on getting the post monsoons rain the seeds germinate.
Dimerias show remarkable colour changes as they grow from the juvenile to mature stage. In some areas the colour of the vegetation shows a gradual change from green to golden yellow, and from green to reddish brown in some other places. This is attributed to the formation of pigments called anthocyanins.
