This is one of the dwarf Euphorbias. According to literature it may become 15 cm tall, but the ones I have seen up to now were only a few cms. The pictures were taken south of Laingsburg, along the old road from Montagu to Ladismith, on the following dates: 1 and 2: 7 July 2009; 3: 1 May 2011; 4 and 5: 30 June 2013 (in other words: yesterday).
