Crassula tetragona subsp. robusta

These Crassula tetragona subsp. robusta leaves are in good shape, cared for in the Stellenbosch University Botanical Garden. The smooth, green, decussate leaf pairs curve up near stem-tips, pointed like cattle-horns. Turned straight lower down, some fail to even manage that, sagging in a few cases.

The hairless stems are green among the new leaves, brown to greyish lower down and slightly shiny, ringed at the nodes. Plants reach up to 1 m in height.

The small flowers grow in clusters at stem-tips, opening late in summer. They are tiny and bell-shaped, creamy white fading to brown.

Subsp. robusta occurs in a smallish inland part west of centre in the Eastern Cape. 

The habitat is Karoo scrub in semi-arid terrain, the plants growing in partial shade. The plant is not considered threatened in habitat early in the twenty first century (Smith, et al, 2017; iNaturalist; http://redlist.sanbi.org).
