A plant called tortoise shell grass, its "camouflage" is to deceive some careless herbivores by using the protruding patterns on the stems similar to those on tortoise shells to avoid their swallowing.

In some arid areas, there will be some plants that look like small stones. This plant is called small stone grass. It is very short, the color is grayish brown, and the pattern and color are similar to those of natural stones, which is very realistic.

The growing environment of tortoiseshell:

Like a turtle in the hot and dry season, it is like a curled turtle lying on the ground, seemingly lifeless.

But when the rainy season comes, it quickly grows slender branches and lush leaves from the top of the turtle-shell-shaped stem, and grows, blooms and bears fruit quickly. In the dry season, the lush branches and leaves wither and fall off immediately, leaving only short stems like turtle shells still alive. Because the short stem is protected by the shell, it can prevent the water inside from evaporating, so it can save life.

Turtle grass is a monocotyledonous plant of Dioscoreaceae, which is closely related to yam. Because it has the ingenious ability to adapt to drought and protect itself, it can be safe even if it doesn't rain for one hundred days in the dry season. It will flourish again in the next rainy season.
