TRIBE 4. PERSOONIEÆ.&mdash;Anthers all perfect, with parallel cells adnate to the connective, the stamens inserted at or below the middle of the perianth-segments. Ovules 2, or sometimes 1. Fruit a drupe or rarely a dry nut or membranous.

SUBORDER 2. FOLLICULARES.&mdash;Fruit dehiscent, follicular or 2-valved or rarely drupaceous and indehiscent. Flowers usually in pairs, with a single bract to each pair, or rarely the inflorescence anomalous. Ovules 2 or more, collateral in each pair.

TRIBE 5. GREVILLEEÆ.&mdash;Ovules 2 or 4, all collateral. Seeds without any intervening substances or separated only by a thin lamina or mealy substance. Flowers in racemes or rarely in umbels or clusters, with deciduous or abortive bracts or rarely surrounded by an involucre or imbricate bracts.

TRIBE 6. EMBOTHRIEÆ.&mdash;Ovules several, imbricate in 2 rows. Seeds usually separated by thin laminæ or a mealy substance, (possibly the outer coating of the seeds detached and united as in Banksia).

TRIBE 7. BANKSIEÆ.&mdash;Ovules 2, collateral. Seeds separated by a hard or membranous, usually bifid, sometimes double plate, rarely wanting. Flowers in dense spikes or cones with closely imbricate persistent bracts within or below the spike.

The singular plate intervening between the two seeds in this tribe has been explained by Brown to consist of the outer coating of one side of each seed, separating from the inner coatings as they advance towards maturity, the two becoming usually consolidated opposite the nuclei, remaining distinct opposite the seed-wings. This plate is entirely free from the walls of the pericarp, except at the point of attachment of the seed, forming a portion of the latter, not of the former, and has therefore no title to the name of a dissepiment, real or spurious, still given to it in systematic works, evin in the Prodromus.
