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, thoiigh 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, Lipskii, arcuata and dendroides. 



S. microsperma is the only one of the species examined 

 by me which belongs to the third group. As shown in 



Fig. 79. Transverse sections of: A, Siiaeda microsperma; B, Suaeda Lipskii. 

 In B the veins are indicated by liorizontal hatching. (X 203). 



fig. 79, A, the palisades and the starch-sheath of this species 

 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
