1. Taxonomic Insights

Species: Jasminum angustifolium (L.) Willd.

Family: Oleaceae

The Oleaceae family, commonly known as the olive family, is a group of flowering plants that includes trees, shrubs, and climbers. It is of significant economic and cultural importance, providing essential resources like olives and olive oil (Olea europaea), as well as many popular ornamental plants like lilacs (Syringa), forsythia, and jasmines (Jasminum). The genus Jasminum is the largest in the family, with over 200 species, most of which are native to tropical and warm temperate regions. They are characterised by their opposite or whorled leaves and their often fragrant, tubular flowers.

Taxonomic Note: The species was first described by Vahl and later reclassified by Willdenow . It is a scrambling shrub with glabrous stems and simple, highly variable leaves that are typically 1.3-5 cm long, ovate-oval or ovate-lanceolate in shape, and rounded at the base . The flowers are solitary or appear in threes on long slender pedicels, with a corolla tube about 1.6 cm long and 7-8 lobes that equal the tube in length . The fruit is a broadly ovoid berry, about 8 mm in size, with both carpels usually developing . It is known for its fragrant flowers, and it has a synonym, Jasminum sessiliflorum, for a variety with sessile flowers.
