📚 Overview
Description
Celosia trigyna is an upright herb, which can reach up to 1 m high, with an angular and slightly branched stem. The leaves are simple, alternate, with long-stalked triangular ovate lamina. At the base of the petioles are 2 sickled foliaceous structures, characteristics of this species. The flowers are very small and are assembled in discontinuous white balls at the ends of the branches. The fruits are small globular capsules
Cotyledons
The cotyledons are lanceolate to elliptical. They are slightly stalked and are 10 mm long and 3 mm wide
First leaves
The first leaves are simple and alternate. They are oval and held by a petiole almost as long as the leaf blade.
General habit
Erect plant, more or less branched. It is 40 to 100 cm high.
Underground system
The plant has a taproot system.
Stem
The stem is full and very angular, generally having five very marked angles. It is glabrous.
Leaf
The leaves are simple and alternate. They are carried by a long stalk of 3 to 8 cm, almost as long as the leaf blade. The lamina is oval to nearly triangular, 5 to 8 cm long and 3 to 6 cm wide. The base is wedged and sometimes almost perpendicular to the petiole. The top is wedged. Both sides are glabrous. The margin is entire, finely scabrous. They are marked by 6 to 10 lateral ribs. A very remarkable feature of this species is the presence of 2 sickled foliaceous structures, 10-15 mm long at the base of the leaf, surrounding the stem. These foliaceous structures, which resemble to stipules, correspond to the first leaves of axillary branches more or less developed. This character appears as from the fourth or fifth leaf.
Inflorescence
The inflorescence is composed of clusters of tiny white flowers. These clusters are themselves arranged in terminal and discontinuous spikes discontinuous, more or less branched.
Flower
The flowers are formed by 5 elliptic membranous structures, white in color and measuring 1.5 to 2 mm long. Inside these parts are 5 pink stamens and a globular ovary surmounted by a very short three branched style.
Fruit
The fruit is a dehiscent capsule, globose. It measures 1.5 to 2 mm high and 1.2 to 1.5 mm wide. The opening is done by detachment of the upper half of the capsule. This is topped by the short trifid style 0.3 mm high. One capsule contains 4 to 8 seeds.
Seed
The seed is kidney-shaped. It measures 0.8 mm in diameter and 0.2 mm thick. The seed coat is shiny black

Northern Cameroon: Celosia trigyna is uncommon in early rainy season. Germination takes place in June when the rain becomes heavy and regular. The germination takes 1 to 2 weeks, but may be delayed by tillage at the start of cultivation (plowing, weeding). Flowering starts in August and fruiting occurs three weeks later. Fruiting continues until the plant dries out at the start of the dry season (November). A full development cycle lasts three months when germination takes place in June and only 3-4 weeks old when germination takes place at the end of the crop cycle. The flower development is linked to shortening of day length.
Madagascar: C. trigyna occurs in the middle and at the end of the cycle of rainfed crops.

Ecology
Northern Cameroon: Celosia trigyna is a very common weed of annual crops in regions of Sudano-Sahelian climate Sudanese whose annual rainfall exceeds 800 mm. It is then present in 30% of the plots. It has no significant preference for the soil type and grows both in both ferruginous degraded soil and on planosol. In the Sudano-Sahelian region, it is very rare and only grows on high water retention soil. It is a weed characteristic of cultivated plots for many years and subject to semi-intensive crop management (animal traction, mineral fertilizer) or intensive (animal traction, strong mineral fertilizers and repeated use of herbicides pre- lifting of cotton). It belongs to the floristic procession of Commelina benghalensis. Although common in Sudan zone, it is rarely abundant.
Madagascar: The species grows on ferralitic soils, ferruginous soils and fertile alluvium in quite sunny areas. It is a weed of rainfed crops (corn, cotton, peanuts) in semi-arid and sub-humid areas, up to 1200 m altitude in semi-intensive culture systems without fertilization. The concerned agro-ecological zones in Madagascar are the Southwest, West, Northwest and Highlands.

Local harmfulness
Madagascar: Celosia trigyna is a weed of medium frequency and of generally low to medium abundance in rainfed cultivation: rainfed rice, cotton, corn. At the end of the cycle, it can be inconvenient for the harvesting operations due to its vegetative development.
Mauritius: absent.
Reunion: absent.
