House of the Tree
The "Book of Lost Tales 2" contains a description of the 11 Houses of the Gondolindrim, known in canon only through Glorfindel of Gondolin of the House of the Golden Flower and Galdor of the Tree.
The House of the Tree was a great House who wore raiment of green. They fought with iron-studded club or with slings. Their lord Galdor was held to be the most valiant of the Gondolindrim save Turgon alone. He survived the downfall of Gondolin, and it is possible that he lived in the Falas until the Third Age, as an elf called Galdor of the Havens was present at the Council of Elrond.
