Description: Prickly pear resprouting following a fire. Urs Kreuter (USA) says that hot fires can kill prickly pear-type cacti. This fire was not particularly hot, mainly as it occurred late in the day (about sunset) under relatively cool, if windy, conditions.

Description: These seeds are the major dietary component of Bat Eared Foxs during summer months in the Western Cape, South Africa, near Villersdorp. I assume they are some sort of fleshy fruit. Literature generally states Bat Eared Foxes diet is mainly termites, but these results suggest over summer months in this locality they mainly eat this mystery fruit. Attempts at germinating have not been successful. Does anyone know what they might be? Your assistance would be extremely valuable!!
