Lepyrodia cryptica B.G.Briggs & L.A.S.Johnson
Family Restionaceae
Lepyrodia cryptica B.G.Briggs & L.A.S.Johnson APNI*

Description: Dioecious, forming diffuse patches of clusters of culms joined by rhizomes. Rhizome creeping, c. 5 mm diam.; scales red-brown, scarious, extending to c. 4 cm up the culm. Culms usually closely spaced, occasionally to 1 cm apart, erect, terete to slightly flattened, 40–90 cm long, 0.6–1.8 mm diam., smooth to slightly rugose, simple, with branched inflorescence.

Sheaths 4 or 5, persistent, 1.5–4.0 cm long, loose, lax or reflexed, usually with inrolled margins, red- to dull-brown, obtuse to truncate; auricles membranous; lamina erect, to c. 5 mm long.

Inflorescence 2.5–11 cm long; branches to 4 cm long, moderately crowded with flowers, lower branches spaced further apart on the culm, upper branches more clustered; spathes usually exceeding branches, 1.3–2.0 cm long; bracteoles 2, shorter than the tepals, cuspidate. Male flowers: tepals rigid, yellow-brown, lanceolate; outer tepals longer, 3.2–4.0 mm long; inner tepals 2.9–3.5 mm long; filaments c. 2.0 mm long; anthers c. 2.0 mm long. Female flowers: tepals similar to males; outer tepals 3.0–4.2 mm long; inner tepals 2.5–3.5 mm long.

Seeds ellipsoidal, 1.2 mm long, 0.7 mm wide, colliculate with small cells which are prominently ridged.

This can be difficult to distinguish from L. scariosa if the seed ornamentation (or the pattern of this imprinted on the inner face of the capsule) is not visible, so male plants may be particularly difficult to distinguish. It generally has a more compact inflorescence with shorter, more abruptly tapered spathes and smaller flowers in both males and females. It appears to hybridise with L. anarthria where their ranges overlap.
