Abstract
Carallia brachiata, a member of the Rhizophoraceae family, contains various bioactive compounds with antioxidant, anti-inflammatory, and antibacterial properties.The present study applied microanatomical methods to the roots, stems, and leaves of Carallia brachiata to provide botanical data for classification, conservation, and genetic resource development. Primary roots were characterized by five to six xylem bundles and well-developed cortical and pith parenchyma. Secondary roots exhibited a thick periderm and prominent secondary vascular tissues, enhancing mechanical support and conduction capacity. In the primary stem, open vascular bundles were arranged in a ring and surrounded by a continuous sclerenchyma layer. In the secondary stem, secondary xylem occupied most of the cross-section, reflecting increased mechanical reinforcement. The leaf blade consists of well-differentiated mesophyll tissues, with palisade parenchyma more developed than spongy parenchyma. Anomocytic-type stomata were confined to the abaxial surface, reducing water loss. The midrib and petiole feature collenchyma concentrated at the protruding angles and a crescent-shaped vascular bundle enclosed by sclerenchyma. Overall, the microanatomical structure of C. brachiata demonstrates mechanical and conductive development and strong adaptation to dry, high-light environments.
