Cistanche phelypaea
A single cluster of this parasitic species was noted in lower Karkur Talh in October 2006, in a dried state. The host Aerva persica was also completely dry. The cluster was not observed in October 2005 following the rains of 2005, however the host plant was in a fresh state at that time.
In late December 2007, Alessandro Menardi-Noguera observed a growing specimen emerging from the gravel in upper Karkur Ibrahim, approximately 5 months after the rain event that year.
In November 2017 a sprouting cluster was observed, just emerging from the ground in a dried-out pool near one of the few still green Aerva persica plants remaining from the growth following the 2014 summer rains.
In March 2019 numerous examples were noted along a several hundred metre stretch of the lower Karkur Delein, on Morettia philaeana hosts, following localised but apparently quite heavy rains in the summer of 2018.
