BIONATURE

Trichomes are found in a wide range of species and are essential to plant development. Trichomes are epidermal appendages that are frequently seen on the leaves, stems, and fruits of plants. There are two types of trichomes: glandular and non-glandular. Blumea species' immature leaves and stem, which were between one and three centimeters away from the stem tip, were divided into slices, peeled out of layers, and examined under a light microscope at X4, X10, X40 and X100. Results show that the most significant difference in the Blumea obliqua (L.) Druce has biseriate glandular trichomes with multicellular foot while Blumea laciniata (Roxb.) DC. has biseriate glandular trichomes with multicellular head and anomocytic type of stomata observed in both species. With the use of a light microscope, authors performed a thorough investigation to categorize and characterize the trichomes present on the stem, as well as on the adaxial and abaxial surfaces of leaves of Blumea obliqua (L.) Druce and Blumea laciniata (Roxb.) DC. Because it offers thorough comparative data on the trichome shape and stomatal traits of two prominent species of the genus Blumea, this publication is essential for the scientific community. The study provides important anatomical and taxonomic information that can help distinguish, identify, and classify closely related species. Additionally, characterising glandular and non-glandular trichomes advances our knowledge of plant adaptive traits and their potential pharmacological and ecological significance. Future study on plant anatomy, systematics, medicinal plants, and evolutionary biology will benefit from the discoveries.
