Sesbania somalensis was described in 1963, and is listed as of Least Concern by the IUCN.

Taxonomy

The species was described by Jan Bevington Gillett in 1963.[2]

Distribution

Sesbania somalensis is native to the seasonally dry tropical biome of Ethiopia, Kenya, and Somalia.[3] It occurs on the Haud.[1]

It grows near rocky water courses, on red soil and sun-baked mud, in dry scrubland dominated by Acacia and Commiphora.[4] The species is present at elevations of 300–1,300 metres (980–4,270 ft).[1]

Description

Sesbania somalensis is a semi-woody herb that grows 0.5–1.5 metres (1.6–4.9 ft) high.[4]

The plant has oblong leaflets, which are up to 13 millimetres (0.51 in) long, and up to 4.5 millimetres (0.18 in). The leaflets are in seven to fifteen pairs.[5]

The inflorescences are racemes with three to six flowers. The flowers have 6–10 millimetres (0.24–0.39 in) stems. The calyx has a 1.5 millimetres (0.059 in) long receptacle, and a 3.5 millimetres (0.14 in) long tube. The standard is elliptical, 12–18 millimetres (0.47–0.71 in) long, and 12–19 millimetres (0.47–0.75 in) wide. The claw is 4–5 millimetres (0.16–0.20 in) long.[5]

The fruit is a pod, measuring 8–14 centimetres (3.1–5.5 in) long, and around 2.5 millimetres (0.098 in) wide. The pod has eight to twenty-five seeds, which are around 4 millimetres (0.16 in) long, and 1.8 millimetres (0.071 in) wide.[5]

Sesbania somalensis is sometimes confused with Sesbania bispinosa.[4]

Conservation

In 2010, the IUCN assessed Sesbania somalensis as of Least Concern. The population is thought to be stable, and faces no known threats.[1]

Nomenclature

In the Somali language, the species is known as Leboi Yer,[6] meaning "little Lebi." The name is also used for other species of Sesbania.[7]
