430 MISS H, BANDULSKA ON THE CUTICLES OF 
NOTHOFAGUS ANTARCTICA Forst., var. ULIGINOSA, A. DC. Lower Epidermis 
(Pl. 89. figs. 7, 8). 
The stomata are grouped into areas by delicate venules 3-4 cells wide 
which bear numerous 2-celled hairs, each with a bulbous basal cell and an 
elongated very thick-walled terminal cell. Bach stoma is surrounded by a 
group of 5-9 radially-disposed parenchymatous cells. The stomata vary 
much in size. They have a very thick cuticular poral rim, but no well-marked 
T-shaped thickening at the junction of the guard cells. The average 
diameters of the guard cells are ‘027 mm. by ‘025 mm. On some of the 
veins there are little mound-like groups of cells, radially arranged, which 
appear to be the bases of much larger multicellular hairs or emergences. 
Upper Lpidermis—The parenchymatous cells are distinctly larger than 
those of the lower surface. The venules bear numerous 2-celled hairs whose 
average distance apart is "076 mm. (see text-fig. 5).

Hair of Nothofagus antarctica. 
The length of the hairs above the base is very variable. The venule cells 
are practically the same size as those of the lower epidermis, their average 
diameters being equal.

This is closely covered with tubular hairs arising from 5-8 radially-

grouped cells. They much obscure the straight-walled parenchyma and

enclose the stomata. These are very variable in size, and have very strongly- 
thickened poral rims but no “T” piece at the poles. Venules crowded with 
hairs intersect the surface. The guard cells measure on the average ‘O19 mm. 
by ‘017 mm. 
Upper Epidermis.—The cells are thick-walled with an occasional hair-base 
among them, but these are very few and bear no hairs. This xerophytic 
species is, as regards its cuticular measurements, an aberrant type.

The stomata are scattered and in less definite groups than is commonly the 
case, but are separated irregularly by venules of variable width. Hairs do 
not occur on the lower surface. The parenchyma between the guard cells is 
regular, abundant, and straight-walled. Bach stoma is bounded by a very
