Orthochilus ensatus (Eulophia ensata), one of my favorite flowers.
Every November I wait for these beautiful grassland orchids to show their face. A terrestrial orchid I have found them in the Howick, Pietermaritzburg and Eshowe areas (commonly). The plant can easily be missed as it looks very similar to the grass around it but the flower is spectacular and can be seen from hundreds of meters away. A beautiful yellow explosion. Here are a few images of the plant taken near Pietermaritzburg on the Duzi. The plant was recently moved from the genus Eulophia to Orthochilus (I am not a taxonomists but the move seemed obvious).
