Abstract
Aglaia cucullata is the sole member of the genus Aglaia that is regarded as a true mangrove species. The plant was discovered in the mangrove forest of Thailand's peninsular region. Anatomical structure has a significant impact on how a plant functions and adapts to its environment. The plant samples were collected from Tha Pom Klong Song Nam, Krabi province, a mangrove forest of Thailand. The materials were processed into permanent slides using a paraffin method, a sliding microtome technique and scanning electron microscopic technique. The anatomical characters of root, stem, petiole, petiolule, rachis, leaf and wood were investigated. The results revealed that the vascular system of the petiole and petiolule are heart-shaped, whereas the rachis appears concave shaped on both sides. These features are essential for taxonomic identification. Additionally, the multiseriate aseptate peltate trichomes discovered in this study are also exclusive to this genus. Anatomically, multiple palisade mesophyll, tanninferous cells and crystals were are observed. The results of this study revealed that anatomical traits can be used to certify the species and to understand how the plant adapts its structure to survive in severe environment.
