Haworthiopsis glauca

Haworthiopsis glauca, formerly Haworthia glauca, is a species of flowering succulent plant from the Eastern Cape Province, South Africa.
Description.
"H. glauca" typically has pointed, light blue succulent leaves ("glauca" = "blue"), which are packed densely along its stems. The stems branch from the base, and the plant can form clumps.
The leaves of this variable species are sometimes incurved, sometimes vertical & erect, and sometimes spreading. In some varieties, the leaves have slight tubercles.
Among the more common varieties are "var. herrei" (with tubercles) and the gracile "var. jonesiae" (with pencil-thin stems).
Taxonomy.
The species was previously included in "Haworthia" subgenus "Hexangulares". Phylogenetic studies demonstrated that subgenus "Hexangulares" was actually relatively unrelated to other haworthias and so it was moved to the new genus "Haworthiopsis".
Distribution.
This species extends across the western part of the Eastern Cape Province, South Africa. It can be found as far south as the vicinity of Port Elizabeth and westwards as far as Paardepoort near the border between the Western & Eastern Cape provinces.
Within this range, it typically grows in very well-drained sandy soil, either in direct sunlight, or under a bush or rocks which serve as partial protection from the sun.
