Common name: Mountain Lettuce, Cattleman's Lettuce
Podolepis robusta (Maiden & Betche) J.H.Willis APNI*
Synonyms: Podolepis longipedata var. robusta Maiden & Betche APNI*
Description: Perennial herb to 80 cm high with multiple shoots arising from basal rosette. Taproot stout.
Basal leaves oblanceolate, 4–20 cm long, 1.5–5.5 cm wide, with obtuse to broadly acute apex, glabrous, light green, rarely moderately to densely white-woolly, stems and cauline leaves with woolly indumentum.
Inflorescence a narrow loose corymbose panicle, almost flat topped, 3–11 heads. Heads yellow to orange, 25–40 mm diameter. Claw of intermediate involucral bracts usually c.1 mm wide, 5–10 mm length, with with pale brown to purplish glandular hairs. Ligulate florets 19–13 mm long with 3–5 teeth. Disc florets 6–10 mm long.
Pappus bristles c. 4–8.5 mm long, barbellate with teeth. 0.1 mm long. Achenes sparsely scabrid in upper part, 2.5–3.0 mm long.
Flowering: Flowers in summer.
Distribution and occurrence: Reasonably common and widespread throughout the Australian Alps Biogeographic Region (Commonwealth of Australia 2012), from Mt Ginini (Namadgi National Park, Australian Capital Territory), through the Snowy Mountains (New South Wales) and virtually throughout the Victorian alps and subalps as far south as the Baw Baw Plateau.
Podolepis robusta usually occurs above the (Eucalyptus pauciflora) treeline (or below where the treeline is inverted in cold-air drainage hollows). It typically occurs in subalpine/alpine grassland and open heathland. Where P. robusta and P. laciniata are ± sympatric, P. robusta will nearly always be found at higher elevations but, in a few instances, the two may occur in mixed populations. Altitude range c. 1200–1920 m.
