Mesua thwaitesii, is a species in the family Calophyllaceae. It is endemic to Sri Lanka, where Sinhalese people called "Diya Nā - දිය නා".[1] The plant is highly valuable as a medicinal plant within the country. [2]
Chemistry
Timber, seeds and bark of Mesua thwaitesii is known to have Xanthones and 4-phenylcoumarins.[3]
Taxonomical controversy
Mesua ferrea is a complex species and has recently been split into several species and varieties.[4] A.J.G.H. Kostermans and Gunatilleke et al. call the tree described in this Wikipedia article Mesua nagassarium. Kostermans lists several subspecies of Mesua nagassarium.
These authors list Mesua ferrea as a separate species that is endemic to Sri Lanka and is a small, 15 meters high tree that grows near streams and in marshes in the Southwest of Sri Lanka, where it is called "Diya Na" in Sinhala, meaning "Water Na Tree". This "Diya Na" is not cultivated.[5] Gunatilleke et al. (p. 139), however, remark in a footnote: "In the most recent revision diya na is named as Mesua thwaitesii and na as Mesua ferrea".
Kostermans and Gunatilleke et al. classify Mesua ferrea in the Clusiaceae family, while in the AgroForestryTree Database it is allocated to the Guttiferae family.
