Haworthia lockwoodii drying out for summer

Leaf-tips of Haworthia lockwoodii become conspicuously dried out and white in the plant’s rest season habitat. This is the hot, dry summers of the Witteberg part of the Karoo near Laingsburg where these plants grow. Rain falling in autumn and winter is scant, from 125 mm to 250 mm per annum.

The seasonal adaptation process goes further than seen here, more of the leaf material reduced to white, papery "hats" for the residual plant core that also withdraws into the ground for escaping the elements.

In picture, there is some translucence in the soft, smooth leaves. Even the outer, old leaves still tend to be slightly incurved here, or at least erect with the desiccated leaf parts mainly fallen inwards (Scott, 1985; http://haworthia-gasteria.blogspot.co.za).
