CXI. PROTEACEiE. 
Tribe II. Conospermeae. Anthers: one with 2 perfect cells, two with 1 perfect and I 
abortive cell, the fourth abortive, the perfect cells broad, concave, erect, without any connective,, 
the adjoining ones of distinct anthers applied face to face in the bud forming a single cell, all on 
very short thick filaments at the base of the lamina: or at the summit of the tube of the perianth. 
Ovule 1. Fruit a dry nut. 
Lower anther abortive. Stigma raised above the stamens on the beak-like 
end of the style. Nut turbinate, fiat and comose on the top. Leaves 
entire 3. Conospermum. 
Tribe III. Persooni ex.— Anthers all perfect, with parallel cells adnate to the connective, 
the stamens inserted at or below the middle of the perianth-segments. Ovides 2 or sometimes 1.

terminal raceme by the abortion of the floral leaves. Ovules 2 or 1.

Series 2. Folliculares. — Fruit dehiscent, follicular or 2-valved, drupaceous and inde- 
hiscent. Flowers usually in pairs, with a single bract to each pair, rarely (in Carnarvonia,

Tribe IV. G-revilleeae . —Ovules 2 or 4, collateral. Seeds without any intervening sub- 
stances or separated by a thin lamina or mealy substance. Flowers in racemes or clusters, with 
deciduous or abortive bracts, or with an involucre of imbricate bracts.

anthers on short filaments attached below the laminae. Style cylin- 
drical or more or less elavate at the end. 
Flowers pedicellate, in pairs, in racemes. Fruit with a fleshy indehiscent 
exocarp and cartilaginous endocarp 5. Helicia. 
Flowers in racemes or panicles. Fruit with a more or less coriaceous 
2-valved exocarp and horny endocarp 6. Macadamia. 
Flowers sessile, in pairs, in cylindrical spikes. Fruit thick and woody, 
tardily dehiscent. Leaves opposite 7. Xvlomelusi. 
Flowers sessile or nearly so, in pairs, in cylindrical or oblong spikes. 
Fruit a follicle. Leaves alternate 8. Orites. 
Ovules 2. Perianth straight. Anthers short and sessile with the concave 
lamin®. Leaves alternate. 
Ovules orthotropous, pendulous. Fruit indehiscent 9. Kermadecia. 
Fruit indehiscent, seeds solitary oval-globose 10. Hicksbeachia. 
Flowers solitary or in twos or threes, axillary. Perianth-tube almost 
slraight, the laminae soon free. Follicle l seeded 11. Strangea. 
Ovules amphitropous, laterally attached. Fruit a follicle. 
Seeds without wings or the wings short at both ends or annular. In- 
florescence terminal, rarely also axillary 12. Grevillea. 
Seeds winged, chiefly or entirely at the upper end. Inflorescence 
axillary 13. Hakea. 
Ovules 4, collateral. Perianth revolute in the bud or straight and regular. 
Anthers short and sessile within the concave laminae. Fruit a 
follicle. Leaves alternate. 
Flowers solitary or clustered on irregularly branched peduncles. Fruit 
a follicle. Leaves alternate, compound 14. Carnarvonia. 
Perianth revolute in the bud. Hypogynous gland unilateral or semi- 
annular. Follicle short and broad 15. Buckinghamia. 
Perianth straight. Hypogynous glands 4. Follicle oblong, recurved . . 16. Darlingia. 
Tribe V. Embothrieae . — Ovules several, imbricate in 2 roics. Seeds usually separated 
by thin lamina or a mealy substance. 
Flowers in spikes often clustered. Hypogynous glands usually 3, distant, 
attenuated upwards. Exocarp almost woody 17. Musgravea. 
Flowers in long pendulous racemes, and lateral, or shorter erect and nearly 
terminal. Hypogynous glands 4, roundish, somewhat connate . . .18. Holland/ea. 
Hypogynous glands 4. Ovules imbricate downwards. Seeds with narrow 
wings all round .... 19. Cahdwellia.

Hypogynous glands 3. Ovules imbricate upwards. Seeds winged at the 
upper end 21. Lomatia. 
Flowers in dense racemes ; follicles oblong coriaceous. Seeds in 2-series 
with an oblong terminal wing 22. Ehbotiirium. 
Tribe VI. Banksieae . — Ovules 2, collateral. Seeds separated either by a hard usually 
woody subtance or by a membrane rarely wanting. Flowers in dense cones or heads.
