Mimetes cucullatus is an evergreen, upright shrub of 1–2 m (3–7 ft) high, that has a firm woody tuber in the ground, from which several stems rise. These stems are upright, 3–8 mm (0.12–0.32 in) thick, mostly not branching but occasionally forking, initially covered in grey felty hair, but this tends to wear off with age. The leaves are alternately set along the stems, very narrow to broad elliptic or inverted egg-shaped, 2½–5½ cm (1–2¼ in) long and ½–2 cm (0.2–0.8 in) wide. Young growth is scarlet coloured, turning green lower down the stem. The leaves that subtend the flower heads are inverted fiddle-shaped in outline, folded backwards from the midline out, and during flowering are scarlet in the upper parts, gradually turning through yellowish to green at the base or entirely yellowish with a green base or softly orange. The
inflorescence that consists of many flower heads in the axils of the highest leaves on the stem is cylindric in shape and 6–10 cm (2½–4 in) long and 4–7 cm (1⅔–2 in) in diameter, topped by a tuft of smallish, more or less upright, narrowly egg-shaped, scarlet coloured leaves. Each flower head contains four to seven flowers and is subtended by a leaf that is fiddle-shaped in outline and the side bent away from the stem as to cowl over the lower flower head. These leaves are mostly scarlet with some yellow and green at the very base or more rarely entirely yellow with the very base green, while intermediate soft orange forms also occur in the same populations. These leaves have an entire margin or have three teeth near their tips. The
bracts that encircle the flower heads are unequal in size, clasp the base of the flowers tidily, fringed by a rim of silky hairs, and together form a two-lipped
involucre. The bracts below the attachment of the flowers are ellipse-shaped with a pointy tip, larger, 1½–3 cm (0.6–1.2 in) long and 3–12 mm (0.12–0.48 in) wide. The bract above the attachment of the flower heads are smaller, lance-shaped with a pointy tip, 8–10 mm (0.32–0.40 in) long and 1½–3 mm (0.06–0.12 in) wide. The
bract subtending the individual flower is linear with a pointy tip to awl-shaped and 6–10 mm (0.24–0.40 in) long. The
4-merous perianth is 3½–4 cm (1.4–1.6 in) long and curved in the bud. The lower part, that remains merged when the flower is open, is hairless, inflated, and about 1 mm (0.04 in) long. The middle part (or
claws), are each about 10 mm (0.4 in) wide, line-shaped, powdery to thinly silky hairy. The upper part (or
limbs), which enclosed the pollen presenter in the bud, are line-shaped with a pointy tip, difficult to differentiate from te claws and densely silky hairy. From the centre of the perianth emerges a
style of 4½–5 cm (1.8–2.0 in) long. The thickened part at the tip of the style called
pollen presenter is line to awl-shaped, 5–7 mm (0.20–0.28 in) long, with a ring-shaped thickening at its base, a sharply pointy tip and the sigmatic groove across the middle. The oval
ovary is densely silky hairy, about 1 mm long (0.04 in) subtended by four fleshy awl-shaped scales.
Differences with related species Mimetes cucullatus and
Mimetes fimbriifolius differ from all other pagoda species by the gullet-type flower head. It functions in the same way as
Acanthus and many
Scrophulariaceae and
Lamiaceae flowers. The bracts at the side of the stem are smaller, those in sight from the side are enlarged, while the leaf that is subtending the flower head above forms a brightly coloured hood. When the flowers open, the styles grow longer, break free from the perianth, and are pressed in the overhead leaf.
M. fimbriifolius can easily be distinguished from
M. cucullatus by its branching, tree-like habit, the fringe of white hairs along the edge of the leaves, and the longer leaves of 4–7 cm long in
M. fimbriifolius.
M. cucullatus is a shrub with not or shyly branching stems that individually emerge from the ground, and the shorter leaves of 2½–5½ cm long lack a fringe of hairs. == Taxonomy ==
