Haworthia arachnoidea
A small, variable haworthia whose dense rosettes of dark green leaves are wrapped in fine, translucent bristles like cobwebs. It grows across the western half of South Africa's Cape, from Namaqualand south to the Breede River valley and east towards Port Elizabeth, tucked under shrubs and against rocks on dry slopes. It grows in the cool, moist months and shrinks and pulls in its leaves during the hot, dry summer.
Where it grows wild
Rocky hill and mountain slopes, ridges and cliff crevices in succulent Karoo, renosterveld and dry fynbos, often on shale or sandstone. Plants usually sit in the shelter of rocks and shrubs, frequently on cooler south-facing slopes, rather than fully exposed. In dry summers the rosettes dry and contract.
Few records carry an elevation; specimen labels mention about 370 m and 670 m (2200 ft). The range runs from the lowlands of the Breede and Little Karoo valleys to mountain slopes, probably from roughly 100 m to over 1000 m.
