📚 Overview
Description
Global description
Thalia geniculata is a vivacious, glabrous herb that emits large, upright leaves from a creeping rhizome and several upright stems with broad leaves. Stem and petioles are spongy. The limb is wide, crossed by many parallel veins that meet on the margin. The inflorescence is a large, loose panicle with purple flowers clustered in 2 and surrounded by deciduous bracts. The fruit is an elongate ellipsoid capsule that encloses a single seed.
General habit
Vivacious herbaceous rhizomatous plant, entirely hairless. Each plant emits several erect stems about 1 m high.
Underground system
The underground system is a creeping rhizome with many intermingled roots.
Stem
The stem (inflorescence axis) is cylindrical, more than 1 m high and spongy in its lower part.
Leaf
The leaves are simple, alternate, distichous. They usually measure about 1m in height. The petiole is 30 to 60 cm long forming a sheath at the base surrounding the stem. It is spongy in its lower part. The lamina is oval-lanceolate, rounded to sub-cordate at the base, gradually terminating in a broad wedge and shortly acuminate. It is 15 to 40 cm long and 8 to 20 cm wide. It is crossed by numerous parallel and close lateral veins, which join and form a cartilaginous margin. The margin is entire and both faces are glabrous.
Inflorescence
The inflorescence is a large terminal panicle erect, loose with slender branches. It is taller than the leaves. It has purple flowers that open in the morning.
Flower
The flowers are grouped by 2, and consist of 3 purple petals of irregular shapes. Each flower is supported by a deciduous lanceolate white bract 1.5 to 2 cm long, shaped like a boat hull.
Fruit
The fruit is an elongated ellipsoid capsule 1 cm long.
Seed
The seed occupies the entire capsule. It is oblong, of largely elliptical, almost circular in section, black-brown colored

Thalia geniculata can be confused with Thalia dealbata. The later species has larger leaves (1 to 2 m) and a larger inflorescence. The leaves are glaucous green, covered with a whitish bloom on the underside.
