📚 Overview
Description
Global description
Aeschynomene afraspera is a branched or branchless, annual herbaceous plant up to 2 m tall. The central part of the stem is covered with small warts. The leaves are composed paripinnate and alternate. Their base is framed by a pair of appendiculate stipules. Medium in size, they measure up to 20 cm in length and are composed of 25 to 35 pairs of elongated and narrow leaflets. The yellow papilionaceous flowers are grouped on short axillary inflorescences. The fruit is an elongate pod with distinct articles, with a warty surface, dark in color at maturity.
General habit
Annual herbaceous plant erect growth habit with fully hairless plant, which measures 1 to 2 m in height.
Underground system
The root is a taproot.
Stem
The broad and hollow stem contains pith in its central part. Its surface is glabrous, dotted with small warts, especially towards its base.
Leaf
The leaves are composed paripinnate and alternate. The petiole thickened at the base, is 10 to 15 mm long. Its base is framed by 2 appendiculate stipules, 15 to 20 mm long and 3 mm wide, with acute elongated upper part. The spine is 10 to 20 cm long. It carries 25 to 35 pairs of leaflets that are 10 to 20 mm long and 3 to 4 mm wide. They are glabrous, with an asymmetrical rounded base and a rounded or slightly emarginated apex.
Inflorescence
The inflorescences are axillary racemes, 4 to 5 cm long and comprising 1 to 6 flowers.
Flower
Each flower is in the axil of a glabrous leafless bract 3-8 mm long and 2-5 mm wide. The floral pedicel is 5 to 9 mm long. The calyx, 6-8 mm long, is composed of 2 glabrous lobes. The corolla consists of an upper petal or standard 10 mm long and wide petal, upright, golden yellow in color, with 2 lateral petals or wings, short (5 mm) and a lower petal or carina, 10 to 12 mm long, rounded, pubescent, greenish in color.

Life Cycle

The growth of Aeschynomene afraspera up to the 5-leaf stage is slow. Then the growth is faster, the plant reaching 0.6-1.5 m in 2 months. In dense stands the plants develop a single stem while in low density stands the stem branches.
Flowering occurs between 65 days (in short days) and after 80 days (in long days).

Aeschynomene afraspera is a semi-aquatic plant of marshy places and edges of permanent or temporary ponds. It can form dense populations in lowlands and flooded depressions during the rainy season or along the river.
