A species observed by M. Marschall von Bieberstein in 
Southern Tartary, growing in dry spots on the cliffs of the . 
Black Sea. A specimen, found by Dr. Patrick Russell on 
the mountains of Syria, had however been long ago depo- 
sited in the Banksian Herbarium, by the name we have 
cited; but the species was not published until it appeared 
in the “ Flora ‘aurico-Caucasica,” and has not been even 
yet inserted in any general enumeration of vegetables. 
it resembles Eupnorsia Myrsinifes in many respects, but
