Note on the leaves. — The leaves of the opposite 

 pairs in Frankenia grandifolia are joined at base by 

 a narrow membrane which is slightly hairy on the 

 margin. The petioles therefore arise from a shortly 

 sheathing base. In Frankenia palmeri, on the con- 

 trary, distinct stipules are present. The stipules are 

 short, broad and ciliated, each pair being connected 

 ^vith the stipules of the opposite leaf by a narrow 

 border.
