Argophyllum lejourdanii F.Muell. var. lejourdanii, The Queensland Flora 2: 533(1900), Type: ?.
Flowers and fruits as a shrub 1-5 m tall.
Leaf blades about 10-18 x 4-7 cm. Midrib and lateral veins depressed on the upper surface of the leaf blade. Young leaves, twigs and terminal buds clothed in ferruginous prostrate hairs. Old leaves with white or silvery hairs only on the underside of the leaf blade. Lateral veins curved throughout their length but not forming definite loops inside the margin.
Flowers about 4 mm diam. Calyx outer surface and pedicel clothed in white or rusty brown, prostrate hairs. Petals fringed on the inner surface or separate ring of fringed scales or petal-like structures present inside the whorl of petals. Stamens six. Anthers and pollen white. Disk orange, surrounding the base of the ovary. Placenta attached to one side of the ovary and extending about half way across the cavity. Ovules numerous in each locule. Stigma +/- globular, green.
Cotyledons orbicular about 2-3 x 1.5-2 mm, petioles about 1 mm long. First leaf sparsely hairy, produced very close to the cotyledons so that it could be mistaken for a third cotyledon. Cotyledonary petioles shorter than the cotyledons. At the tenth leaf stage: leaf blade underside densely clothed in mainly white hairs, stem densely clothed in brown hairs. Marginal teeth variable in size.
Distribution and Ecology
Endemic to NEQ. Altitudinal range from 50-800 m. Usually grows in open forest but also occurs on rain forest margins and in permanent openings in rain forest caused by factors such as rock slabs and outcrops particularly on granite substrates.
Shrub (woody or herbaceous, 1-6 m tall)
