Habit Shrubs to 5 m tall (exceptionally to 10 + trees to 40 m tall m tall) Stipule margin laciniate
entire Leaf blade membranaceous, margin chartaceous, plane margin revolute Number of lateral 8 to 11 4 to 8 veins on each side Branching, 2-forked, axillary to the 4 to 6-forked, mostly on position and size distalmost leaves, to 1 defoliate branches, to 3.
What is still poorly understood is the position of the many illustrated laciniate pinnule forms within the frond structure of M.
3) hair grew on laciniate forms such as "Odontopteris subcuneata", although much more sparingly than on typical leaves, i.
12 cm, apex obtuse, clavate, slightly separated only along the neck during anthesis, outer surface densely laciniate
, the laciniae to 2 mm long, membranous, patent or pointing backwards, the entire outer surface (including the laciniae) puberulous, the proximal half bright red, the distal half yellow, the inner surface finely puberulous and with a narrowly triangular ligule to 4 mm long at the base of each petal; androecium formed by two alternating series of long and short stamens halfway attached to the petals, anthers oblong, tetralocular, 2-2.
Cypselae truncate at the apex, glabrous to pubescent; pappus with three, rarely two or four, narrowly paleaceous bristles, longitudinally plicate, apically plumose to laciniate
, rarely crown-like.
Plants robust (5-8 mm wide); stem leaves and underleaves laciniate
Sessile, cauline leaves (sometimes improperly called "ligules" on Gunnera): (0) absent; (1) like other leaves, but smaller and sessile; (2) small, straplike; (3) small, shieldlike; (4) budlike; (5) pinnatifid to laciniate
12 cm long, whitish green, very thin and except for the veins transparent when dry, deeply laciniate
with long lobes also from near the base.
