Cheeseman * regards this species as identical with V. Darwiniana, Col., but 
Huchedé + figures a distinct hypoderm in that species, which is absent in my 
material both in the cultivated and in the native material collected by

Cockayne ; this last shows, however, a strengthening layer beneath the 
epidermis at the edges of the leaf, which is absent from the cultivated 
material,

Transverse section of leaf of V. glaucophylla. x 200. 
V. carnosula, Hook. f. 1. 
This species has its leaves very like those of V. glaucophylla, but small and 
not glaucous. The mesophyll shows very little differentiation. The cultivated 
plants agree in all points with native plants from herbaria. 
V. amplexicaulis, Armst. $. 
The leaves are thick and glaucous, concave above and somewhat imbricate 
round the stem. The stomata on the lower side are sunk with considerable 
cuticular protection ; those on the upper side are larger and less protected : 
this is probably due to the position occupied by the leaves. The whole 
mesophyll consists of slightly elongated cells.
