Of these plants only the Inula, the Spartium, and the Euphor- 

 bia are of common occurrence in the macchie- Generally speak- 

 ing, all the species mentioned are much more xerophytic than 

 their neighbors on more level ground. The Compositae (nos. 



1-6) are all aromatic with essential oil; nos. i, 3, and 4 are 



densely sericeous or toraentose, and nos. 3 and 4 have strongly 

 revolute leaves, the margins almost meeting ; no. 2 has fleshy, 

 linear leaf segments, and no. 6 has pubescent varnished leaves.

 is one of the most succulent of the genus, the Medicago has 

 small pubescent leaves, and the Matthiolas are hoary pubescent.
