Tritonia or Flame Freesia are members of the Iris family and these little beauties are not spring flowers, they wait for the rain and are flowering all over at the moment, making eye-catching little patches of orange in among the rocks and grass. Rocky places are their preferred home although these can be grown in pots around the house
The name Tritonia means weather-vane and refers to the arrangement of the stamens, which are black and you can see them on the upper part of the flower in the top picture. The three little yellow spikes at the bottom of the flower entrance are interesting to see: I wonder if those act as a gate, preventing insects from going straight down into the flower and instead guiding them upwards to come in contact with the plant's reproductive parts, probably with their wings or upper bodies. They smell strongest at night so they are probably pollinated by moths, which fits with the fact that red or orange flowers are not primarily pollinated by bees.
