thinly pubescent at the margin only ; lamina 9 mm. long, 5 mm. 

 broad ; petiole 4 mm. long.

Leaves very similar to those of E. saxatile, exstipulate (or stipules 

 adnate to the petiole and margined with long, somewhat feathery 

 hairs), thinly glandular-pubescent on both surfaces, and dotted 

 with sessile glands beneath, light green above, paler beneath, highly 

 odoriferous, especially when bruised.

Fruit and Seed. The ovary consists of a varying number 

 of carpels from three or five to thirty. The number corre- 

 sponds to that of the petals, which in Semper vivum sometimes 

 reaches as many as twenty. They are free, or more or less 

 connate or sunk in the receptacle, and one-celled. The ovules 

 are small, numerous, anatropous, and arranged in two or 

 several series upon the ventral suture ; more rarely are they 

 few or solitary, as in a few species of Sedum and Tillsea. There 

 are also few ovules in the carpels of Dinacria. When few they 

 may be erect or pendulous. The fruit consists of as many 

 follicles as there are carpels, dehiscing along the ventral suture 

 or, where the carpels are connate, along the dorsal suture. The 

 seeds are minute, oblong, with a membranous or subcoriaceous 

 finely reticulated testa, and contain a fleshy endosperm. The
