Is Scutellaria or Catalpa know for its resemblance to miniature medieval helmets?
Scutellaria Scutellaria is a genus of flowering plants in the mint family, Lamiaceae. They are known commonly as skullcaps. The generic name is derived from the Latin "scutella", meaning "a small dish, tray or platter", or "little dish", referring to the shape of the calyx. The common name alludes to the resemblance of the same structure to "miniature medieval helmets". The genus has a subcosmopolitan distribution, with species occurring nearly worldwide, mainly in temperate regions.
Catuaba The name catuaba (pronounced [ka.two.'aba], a Guarani word that means "what gives strength to the Indian") is used for the infusions of the bark of a number of trees native to Brazil. The most widely used barks are derived from the trees "Trichilia catigua" and "Erythroxylum vaccinifolium". Other catuaba preparations use the bark of trees from the following genera or families: "Anemopaegma", "Ilex", "Micropholis", "Phyllanthus", "Secondatia", "Tetragastris" and species from the Myrtaceae.
