Meronyms (members of "Myrtaceae"): myrtaceous tree (trees and shrubs). . Melaleuca reproduces so quickly and so thickly that attempts to eliminate it from the swamps by cutting have met with little success. Several species of trees are 30–50 metres (about 100–165 feet) tall; for example, the Australian mountain ash (E. regnans) of Victoria and Tasmania may attain a height of more than 90 metres (almost 300 feet). Tannins for tanning hides are extracted from the bark and foliage of the Australian Eucalyptus astringens and from the fruits (myrobalans) of Terminalia chebula. In addition, some species of Epilobium have many small-flowered largely self-pollinated species. Grown in Indonesia, Malaysia, and several African countries, the name for this popular spice comes from the Sanskrit Katukaphelah, which became the Greek karyophyllon and from there the English clove. .
