The tree ferns are arborescent (tree-like) ferns that grow with a trunk elevating the fronds above ground level, making them trees. Most tree ferns are members of the “core tree ferns”, belonging to the families Cyatheaceae (scaly tree ferns), Dicksoniaceae, Metaxyaceae, and Cibotiaceae in the order Cyatheales. It is estimated that Cyatheales originated in the early Jurassic,[1][2] and is the third group of ferns known to have given rise to tree-like forms. The others are the extinct Tempskya of uncertain position,[3] and Osmundales where the extinct Guaireaceae and some members of Osmundaceae also grew into trees. In addition there was the Psaroniaceae and Tietea in the Marattiales, which is the sister group to true ferns.

Teak (Tectona grandis) is a tropical hardwood tree species in the family Lamiaceae. It is a large, deciduous tree that occurs in mixed hardwood forests. Tectona grandis has small, fragrant white flowers arranged in dense clusters (panicles) at the end of the branches. These flowers contain both types of reproductive organs (perfect flowers). The large, papery leaves of teak trees are often hairy on the lower surface. Teak wood has a leather-like smell when it is freshly milled and is particularly valued for its durability and water resistance. The wood is used for boat building, exterior construction, veneer, furniture, carving, turnings, and other small wood projects.[2]
Tectona grandis is native to south and southeast Asia, mainly Bangladesh, India, Indonesia, Malaysia, Myanmar, Thailand and Sri Lanka, but is naturalised and cultivated in many countries in Africa and the Caribbean. Myanmar‘s teak forests account for nearly half of the world’s naturally occurring teak.[3] Molecular studies show that there are two centres of genetic origin of teak: one in India and the other in Myanmar and Laos.

Mahogany is a straight-grained, reddish-brown timber of three tropicalhardwoodspecies of the genusSwietenia, indigenous to the Americas[1] and part of the pantropical chinaberry family, Meliaceae. Mahogany is used commercially for a wide variety of goods, due to its coloring and durable nature. It is naturally found within the Americas, but has also been imported to plantations across Asia and Oceania. The mahogany trade may have begun as early as the 16th century and flourished in the 17th and 18th centuries. In certain countries, mahogany is considered an invasive species.
