Stenocarpus R.Br.

Genus

Angiosperms > Proteales > Proteaceae

Characteristics

Trees. Leaves spiral, simple or deeply pinnatifid with few lobes, in the younger stages often twice and thrice pinnate, with very narrow pinnae. Peduncles terminal or in the upper axils, sometimes several in an umbel or short raceme, each bearing an umbel of pedicellate flowers. Bracts 0 or very early caducous. Perianth slightly irregular, the tube opening along the abaxial side, limb nearly globular and recurved, segments at length separating. Anthers broad, sessile, within the concave limb; connective not produced beyond the anther-cells. Disk glands united in a short semi-annular disk or cup, or almost obsolete. Ovary stipitate, tapering into a long style dilated at the top into a flat, oblique disk stigmatic in the centre. Ovules several, laterally attached at or near the top of the cell, imbricate downwards in 2 rows. Fruit a usually narrow-oblong, coriaceous follicle. Seeds produced at the lower end into a membranous wing, separated from each other by a thin lamella.

Trees or shrubs. Leaves simple, variously lobed or compound, alternate, scattered or spirally arranged. Conflorescence terminal or in upper leaf axils, umbellate, sometimes together in umbels or racemes, bracts caducous or absent. Flowers zygomorphic, bisexual; tube opening on lower side; all 4 segments finally separating; limb globular, recurved. Anthers broad, sessile; connective not extended. Hypogynous glands united into a disc or cup, sometimes very reduced. Ovary stipitate; ovules numerous, in 2 rows. Pollen presenter a flattened, oblique disc. Fruit follicular, mostly narrowly oblong or cylindrical, or flattened and semi-circular (1 species), splitting down 1 side. Seeds numerous, in 2 rows, highly compressed, winged.
