Atriplex lindleyi

Citation: Moq. in A. DC., Prod. 13, 2:100 (1849).

Synonymy: A. halimoides Lindley in T.L. Mitchell, Three Exped. Int. eastern Austral. 1:282 (1838), nom. illegit., non Tineo (1827).

Common name: Baldoo, eastern flat-top saltbush (not applicable to all subspecies).

Annual or short-lived perennial c. 30 cm high, monoecious; leaves thin, narrow-obovate to rhomboid-orbicular, acute or obtuse to rounded, cuneate at the base, in all c. 20 mm long, margin coarsely sinuate-dentate to entire.

Male flowers in small glomerules towards the branch apices; female flowers in scattered axillary clusters.

Fruiting bracteoles apparently sessile, united except near the apex, strongly dorsiventrally flattened to spongy-turbinate or subglobose, variously winged around the apex or with opposite erect circular wing-like appendages, in all 5-18 mm long and wide, prominently or minutely apiculate due to the free triangular bracteole apices 1-2 mm high; seed circular; radicle basal, horizontal.

Conservation status: native

Flowering time: No flowering time is available

Taxonomic notes: This species is extremely variable in the shape of its leaves and of its fruiting bracteoles. The type variant approaches subsp. conduplicata in having a pair of dorsal and ventral wings. At the other extreme (represented by the type of subsp. inflata) the bracteoles are subglobose and have almost no wing. Hybridisation probably occurs between the subspecies.

Key to Infraspecific taxa:
1. Fruiting bracteoles more or less turbinate to strongly dorsiventrally compressed; upper surface or lateral margins produced into spreading or ascending wings
2. Fruiting bracteoles dorsiventrally flattened, broadly elliptic to orbicular in outline due to the opposite wing-like appendages that unite to form a winged tube; leaves rounded
subsp. conduplicata 19b.
2. Fruiting bracteoles spongy; wing-like appendages not passing to the base
3. Upper surface of the bracteoles produced into a dorsal and a ventral wing, leaves acute to obtuse
subsp. quadripartita 19d.
1. Fruiting bracteoles subglobose, wingless or almost so; leaves narrow, acute
subsp. inflata 19c.
