Flowering and fruiting: Throughout the year
Occasionally grown as medicinal plants
Native of Tropical Africa
It grows natively in upper Egypt, especially in the Nubian region, and near Khartoum (Sudan), where it is cultivated commercially. It is also grown elsewhere, notably in India and Somalia.
Alexandrian Senna is a shrubby plant that reaches 0.5–1, rarely two, metres in height with a branched, pale-green erect stem and long spreading branches bearing four or five pairs of leaves. These leaves form complex, feathery, mutual pairs. The leaflets vary from 4 to 6 pairs, fully edged, with a sharp top. The midribs are equally divided at the base of the leaflets. The flowers are in a raceme interior[verification needed] blossoms, big in size, coloured yellow that tends to brown. Its legume fruit are horned, broadly oblong, compressed and flat and contain about six seeds.
When cultured, the plants are cut down semi-annually, dried in the sun, stripped and packed in palm-leaf bags. They are then sent on camels to Essouan and Darao, then down the Nile to Cairo or else to Red Sea ports. For the nomadic Ababda, for example, trade in senna provides a significant source of income.
S. alexandrina is also known under the names Egyptian Senna, Tinnevelly Senna, East Indian Senna or the French séné de la palthe
It received the names “Alexandrian Senna” and “Egyptian Senna” because Alexandria in Egypt was the main trade port in past times. The fruits and leaves were transported from Nubia and Sudan and other places to Alexandria, then from it and across the Mediterranean sea to Europe and adjacent Asia.
Historically, Senna alexandrina was used in the form of senna pods, or as a tisane made from the leaves, as a laxative.
Modern medicine has used extracts since at least the 1950s as a laxative. If accidentally ingested by infants, it can cause side effects such as severe diaper rash. The active ingredients are several senna glycosides which interact with immune cells in the colon.

It may be senna italico for
Tirunelveli senna (Senna alexandrina).
It is Senna alexandrina (Cassia angustifolia= Cassia senna). A popular medicinal plant.
The plant has more resemblance to Cassia angustifolia (based on the leaves and fruits)
I have the same specimen and I am agree with …

Isn’t it some Senna species ?
Its certainly not Boswellia -a tree
Though the plant looks like senna I doubt it’s ID as Senna. On careful examination of the flowers the pistil looks like that of a Papilionaceae member. For me even the petals arrangement looks like a Papilionaceae flower. I may be wrong even.
I attach a photograph of a seed pod. Possibly this will be of help to clarify identification. Attachments (1)
Obviously not Boswelia serrata. Cassia or senna sp. sulphuria or surattensis
For me … and … are right i.e. Senna species. The plant has a resemblance to the plant at this link: https://en.wikipedia.org/wiki/Senna_alexandrina.
Thanks, …, for the Id.
I think match with images at Senna alexandrina
