428 MISS H. BANDULSKA ON THE CUTICLES OF 
hair-bases. Bach stoma is bounded by a very thick cuticular rim, and is 
surrounded by a ring of parenchymatous cells irregular in size and grouping, 
and varying in number from 8-10. The average diameters of the guard 
cells are ‘024 mm. parallel to the long axis of the pore and 025 mm. at right 
angles to this. 
Upper Epidermis.—The fine venules are 3-5 cells wide.  Hair-bases 
occur, and consist of a varying number of radially-grouped cells (see 
text-fig. 1).

NOTHOFAGUS PROCERA Oerst. Lower Epidermis (Pl. 39. figs. 3, 4). 
The stomata do not show such definite groupings, nor are the epidermal 
cells arranged round each stoma as in N, Dombeyi. Each pore is bounded 
by a very thick cuticular rim. The guard cells have an average diameter of 
‘028 mm. parallel to the pore, while at right angles to the long axis their 
average diameter is ‘(20 mm. The epidermal cells have wavy walls,

Parenchyma of upper surface. 
Upper Epidermis.—The cells are far more regular in size and less sinuate 
in outline than those of the lower epidermis. A few hair-bases occur (see 
text-fig. 2).
