Lepyrodia verruculosa B.G.Briggs & L.A.S.Johnson APNI*
Synonyms: Lepyrodia cryptica subsp. verruculosa B.G.Briggs & L.A.S.Johnson ms. APNI*
Description: Dioecious, forming dense clumps or diffuse areas of small tufts connected by rhizomes. Rhizome creeping, c. 5 mm diam.; cataphylls tan-brown, scarious, extending c. 5.5 cm up the culm.
Culms closely spaced or up to 1 cm apart along rhizome, erect, flattened (ellipsoid in cross-section), 40–65 cm long, 1.3–2.1 × 0.8–1.5 mm diam., scarcely rough when fresh but asperous and finely tuberculate when dry, simple; lowest internode long, lowest sheath (2–)5–14 cm above the cataphylls. Sheaths 2 or 3 (rarely 4), persistent, 1.5–4.5 cm long, loose, lax or reflexed, usually with inrolled margins, dull-brown, obtuse to truncate; auricles membranous; lamina erect, to c. 1 cm long.
Inflorescence 2.5–19 cm long; branches to 6 cm long and moderately crowded with flowers, lower branches spaced further apart on the culm, upper branches more clustered; spathes usually exceeding branches, 1–3 cm long; bracteoles 2, shorter than the tepals, cuspidate. Male flowers: tepals rigid, yellow-brown, lanceolate; outer tepals longer, 3.0–3.6 mm long; inner tepals 2.5–3.0 mm long; filaments c. 2.5 mm long; anthers 1.7 mm long. Female flowers: tepals similar to males; outer tepals 2.6–3.9 mm long; inner tepals 2.6–3.5 mm long.
Seeds ellipsoidal, 1.2 mm long, 0.7 mm wide, colliculate with small circular raised areas.
Distribution and occurrence: From near Thirlmere (SW of Sydney) to Nadgee on the far South Coast; also Tallong and Pigeon House Range.
On creek banks or seepage areas in heathland and eucalypt forest, mostly on sandstone.
NSW subdivisions: CC, SC, ST
Differs from L. scariosa in having fewer culm nodes, flattened and (when dry) finely tuberculate culms, elongated cataphylls, and different seed shape and surface pattern.
