Trichosclereids are hard needlelike branched cells found in some species of plants that serve the purpose of protecting the plant from herbivores. They are usually approximately 6 mm (1/4 inch) long, but in some species they grow to as long as 1 cm (0.4 inches). Trichosclereids are a type of sclereids that can be found in olive leaves and the aerial roots of the Swiss cheese plant (Monstera deliciosa).

👉 Trichosclereid in the context of Olea
Olea (/ˈoʊliə/ OH-lee-ə) is a genus of flowering plants in the family Oleaceae. It includes 12 species native to warm temperate and tropical regions of the Middle East, southern Europe, Africa, southern Asia, and Australasia. They are evergreen trees and shrubs, with small, opposite, entire leaves. The fruit is a drupe. Leaves of Olea contain trichosclereids.
For humans, the most important and familiar species is by far the olive (Olea europaea), native to the Mediterranean region, Africa, southwest Asia, and the Himalayas, which is the type species of the genus. The native olive (O. paniculata) is a larger tree, attaining a height of 15–18 m in the forests of Queensland, and yielding a hard and tough timber. The yet harder wood of the black ironwood O. capensis, an inhabitant of Natal, is important in South Africa.
