Hippocrepis rupestris Horseshoe vetch
This beautiful plant is found commonly in the Ronda mountains, and is native to southern Spain and NW Africa. I think I have identified it correctly, but someone may tell me I have it wrong. It flowers from March to May and grows to approx. 25cms in height. The seeds are shaped like an horseshoe, but I do not have photographs unfortunately. It is closely related to the Coronillas.
