📚 Overview
Description
Global description
Ludwigia hyssopifolia is an erect plant, totally glabrous with a deeply fluted stem. Leaves are simple alternate, distinctly petiolate and elliptically shaped. The flowers are axillary and solitary. They are formed of a long, inferior ovary surmounted by 4 persistent sepals and 4 yellow, deciduous petals. The fruit is a fusiform capsule, enlarged towards the top where the seeds are arranged in two rows in each of the 4 boxes. The seeds are surrounded by a floury pulp.
Cotyledons
The cotyledons have an oval blade, 5 mm long and 3 mm wide. They are borne by a petiole 4 mm long.
First leaves
The first leaves are simple and alternate. They are distinctly stalked. The blade is oval to elliptical, often tinged with purple.
General habit
Luwigia hyssopifolia is erect. The plant is abundantly branched and can measure 60 cm in height.
Underground system
The root is a taproot but very branched to allow a good attachment in soils saturated with moisture.
Stem
The stem is hollow and strongly grooved. It is totally hairless and most often tinged with purple.
Leaf
The leaves are simple and alternate. They are borne by a thin petiole of 10 to 15 mm long. At the base of the petiole are two small glandular stipules of black color. The blade is elliptical, 5 to 15 cm long and 1 to 5 cm wide. The base and the summit are in cunate. The margin is entire. The limb is traversed by 10 to 15 arched secondary veins. The leaves are dark green to purple.
Flower
The flowers are solitary, located in the axils of the leaves. They are borne by a very short peduncle. The calyx and corolla are located at the apex of the linear ovary, 15-20 mm long. The calyx is composed of 4 triangular sepals 2 to 3.5 mm long. They are spread and always remain attached to the top of the fruit. The corolla is composed of 4 spreading petals, bright yellow in elliptical form. They are 2-3 mm long and 2-2,5 mm wide and are rapidly deciduous. The stamens are 8 in number. They are free, 2 mm long and erect around the style. The anthers are arranged all around the stigma. It is club-shaped, at the top of a thin style and 2 mm long.
Fruit
The fruits are fusiform capsules slightly ribbed and surmounted by persistent calyx. They are 20 to 25 mm long and 2 mm wide. The upper part of the fruit is slightly swollen. Each of the 4 longitudinal boxes contains a large number of seeds. At the base of the fruit, the seeds are arranged in a single row while in the upper part, the seeds are arranged in two rows.
Seed
The seeds are hairless and surrounded by a floury pulp (nucelle). With the nucelle, they form small cylinders 1 mm high, 2 lobes barely marked. Once released from the nucellus, the seeds are ovoid with a broadly rounded base, with a short point. They are 0.8 mm long and 0.5 mm wide. The tegument is finely striated transversely and brown in color.

Ecology
Northern Cameroon: Ludwigia hyssopifolia is a characteristic species of soils saturated with water but not flooded, in the humid lowlands or at the edge of streams. It grows mainly on loamy to silty-clay soils such as alluvium and planosols. This species is found mainly in the Sudano-Sahelian and Sudanian regions with an annual rainfall of over 900 mm. In the Sahelo-Sudanian region, it is replaced by other Ludwigia species such as L. octovalvis.
China: Species dispersed or common in humid, regularly flooded and often disturbed areas, stream banks, roadside ditches, open farmland or openings in moist forests, from sea level to 800 m.
French Guiana: A typical species of marshland places.

Risk Statement
Local harmfulness
Northern Cameroon: Ludwigia hyssopifolia is a weed infrequent in rainfed annual crops such as cotton, groundnuts, sorghum or maize. On the other hand, it is much more common and abundant in lowland rice fields or irrigated vegetable crops.
French Guiana: Plant more or less frequent at the edge of vegetable plots that can contaminate certain long cycle crops such as "dachine" (Alocasia sp. Colocasia sp.). It can be punctually (but rarely) abundant.
