Lithops is a genus of succulent plants in the ice plant family, Aizoaceae. Members of the genus are native to southern Africa. They avoid being eaten by herbivores with their camouflage as small stones, and are often known as pebble plants or living stones. "Lithops" is both the genus name and the common name, and is singular as well as plural.
The plants cast their seeds in the soil during the growth period, but they do not germinate in the next season. Their hard coating is impermeable to the water, and thus the seeds remain dormant for a long period of time. This coating together with their small size allows these plants to establish a large seed bank rather deep in the soil.

This indicates a 25 Billion fold difference in seed weight. Plants that produce smaller seeds can generate many more seeds per flower, while plants with larger seeds invest more resources into those seeds and normally produce fewer seeds. Small seeds are quicker to ripen and can be dispersed sooner, so autumnal blooming plants often have small ...
