Proteaceae

PROTEACEAE

Shrubs or trees. Lvs usually alternate, rarely whorled, mostly coriaceous, exstipulate, entire and simple or pinnately lobed. Infl. a spike or raceme, rarely an umbel or fls solitary, often with an involucre. Fls usually regular, sometimes irregular, usually ⚥ (but spp. dioecious in Leucadendron). Calyx petaloid, of 4 valvate segments, cohering lightly at first, later separating. Corolla 0. Stamens 4, opposite the calyx lobes and adnate to them; anthers generally sessile. Ovary superior, sessile or stipitate, 1-locular; hypogynous glands often present; ovules 1-many; style simple, often rigid and persistent; stigma usually prominent, sometimes oblique. Fr. usually an achene, nut, or coriaceous or woody follicle, rarely a drupe. Seed almost always lacking endosperm.

Key

1
Plants dioecious; infls dense, cylindric to globular or cone-like
Plants ⚥; racemes loose, usually ± cylindric, but sometimes short and umbel-like
2
2
Fr. succulent, an indehiscent drupe; perianth orange
Fr. dry, capsular or only partially dehiscent; perianth usually white, pink, or rose to dark red, sometimes yellow or orange
3
3
Fr. either thick and woody, ± indehiscent and nut-like with seeds wingless, or a capsule with valves flat on inner faces and seeds with broad terminal wing sometimes extending down 1 side or rarely down 2
4
Fr. a follicle, usually coriaceous, if woody, then valves with concave inner faces and seeds either wingless or with small annular wing
5
4
Lvs alternate; fr. a woody capsule opening by 2 valves; seed prominently winged
Lvs whorled or subopposite; fr. usually ± indehiscent sometimes with a narrow slit down 1 side, woody and nut-like; seeds wingless
5
Bracts large and coloured, forming an involucre; fls in a dense, congested, head-like raceme
Bracts small, greenish, inconspicuous, or 0; involucre lacking; fls in open, elongated or reduced and umbel-like racemes
6
6
Ovary usually stalked, rarely sessile; ovules 2; seeds not separated by a partition
Ovary sessile; ovules 4; seeds separated by thin lamellae
KNIGHTIA†

55-60 genera, c. 1000-1300 spp., mainly arid or subarid S. Hemisphere, especially southern Africa, Australia and New Caledonia, a few in the Pacific islands, S. America and S.E. Asia, northwards to Japan.

A large number of proteaceous plants are very commonly cultivated in N.Z. for their ornamental fls, these sometimes being exported; of these only Hakea is widely naturalised, while Grevillea, Leucadendron, Macadamia, and Telopea are wild locally. In addition to the above genera, most gardens and parks in warmer parts of the country have one or more members of the South African genera Protea L., and Leucospermum R. Br., and the Australian genera Banksia L. f. and Dryandra R. Br..
