Justification: Collected by Schweinfurth at Kischen in the northern Haggeher mountains in the 19th Century but not seen since. It is suprising that this distinctive plant has not been seen again during the last one hundred years. Kischen is on the main path up to the Haggeher mountains from Hadiboh and is a botanically well-known area which has been extensively surveyed. This species must now be considered Extinct. |

Balfour (Bayley Balfour 1888) noted that his new species was similar to Psiadia arabica, a widespread species on the Arabian mainland, but differed in the absence of sticky glandular hairs. No specimens have been traced and the identity and status of this species remains a mystery. |
