There are several mentions of mahoganies by NPCs around Gielinor as well as in books. The following text is transcluded from Gielinor's flora - trees. The information found within the book is more often than not just flavour text, and does not reflect their properties or uses within the game itself.
A tropical hardwood species producing a straight-grained, reddish timber. Mahogany is relatively free of imperfections and with excellent workability and durability. Because of this, it is prized by high end furniture makers. Mahogany also resists rot, making is attractive in boat cabin construction. Further, being a tonewood means that it is often used for musical instruments, particularly guitars, producing a better tone compared to other commonly used woods, such as maple. The origin of the name is likely a miscommunication of the old Karamjan word m'oganwo.
