beside the starch-sheath, are here wanting. The aqueous 
tissue must therefore be capable of translocation and we 
also find that all its cells contain chlorophyll, though very little. 
The veins, like those in the first group, lie in a curve 
with the concave side upwards (fig. 79, B). In longitudinal 
section they are seen to branch reticulately within the curved 
plane, the transverse section of which is the curve mentioned, 
but not outside it. To this second group belong S. pterantha, 
altissima, Lipskü, arcuata and dendroides. 
S. microsperma is the only one of the species examined 
by me which belongs to the third group. As shown in

lie internal to the aqueous tissue which is quite translucent. 
The starch-sheath immediately adjoins the arc in which the 
veins run and branch. 
Halopeplis pygmaea (Pall.) Bge. 
A halophyte with sheathing and almost globular leaves. 
The epidermis is not very thick and the stomata are not 
sunk. About three layers of rather loosely arranged palisade 
cells are present, abutting internally on the network of finer 
veins which in turn are linked up with the primary vein by
