This variety was discovered by Bosc;i on Iviza and on the neigh- 

 bouring small islets La Grosa, La Eedouia, and El Malvi. It is 

 quite distinct from the var. Ulfordi, and in some resjjects approaches 

 the var. quadrUineata, whilst the var. Ulfordi is perhaps more closely 

 related to the var. filfolensis.
