or at the summit of the cone. Fruit a follicle, usually oblique with the ventral 
suture curved, either coriaceous and opening along the upper margin, or rarely 
woody and opening almost or quite in two valves. Seeds 1 or 2, Hat orbicular 
or oblong, bordered all round by a membranous wing, or narrowly winged at the 
end or outer margin only or entirely wingless. — Shrubs or trees. Leaves alter- 
nate, very diversified in shape. Flowers in pairs along the rhachis of a short 
and umbel-like or elongated raceme, rarely reduced to a single pair ; the racemes 
either terminal or also axillary, rarely all axillary. The indumentum usually 
consists of closely appressed hairs attached by the centre, rarely of erect or 
spreading hairs, and then usually forked at the base or clustered. 
With the exception of a very few species the genus is limited to Australia.

Sect. 2. Ptychocarpa. — Racemes short, often umbel-like. Perianth-tube dilated below

Sect. 3. Plagfiopoda. —Racemes various. Perianth-tube dilated beloiv the middle and 
usually opening on the lower side, revolute under the limb. Torus very oblique, the gland- 
side the shortest. Ovary villous except in a few axillary flowered species. Stigmatic disk very 
oblique or lateral.

less dilated beloiv the middle and usually opening on the lower side, revolute under the limb.
