Glottiphyllum peersii

Glottiphyllum peersii is a rare species of succulent plant, of the family "Aizoaceae". It is indigenous to arid areas near Klaarstroom in the Western Cape, South Africa. 
Description.
This species can be distinguished by its bright, white margins on its slender, upcurved leaves. 
The leaves grow in pairs, that each appear in a decussate arrangement (each leaf-pair at right angles to the previous one, rather than all in the same two distichous rows). Each leaf-pair is also strongly anisophyllous (one leaf is much larger than the other). The larger leaf of each pair has a notch at its base, and the other is very much smaller.
It most resembles its close relative, "Glottiphyllum difforme", that grows to the east. However "G. difforme" has leaves with large, broad teeth.
