   prob. fr. the root ak to be sharp. See {Acute}.]
   1. A genus of leguminous trees and shrubs. Nearly 300 species
      are Australian or Polynesian, and have terete or
      vertically compressed leaf stalks, instead of the
      bipinnate leaves of the much fewer species of America,
      Africa, etc. Very few are found in temperate climates.

      -- called also {gum acacia}, and {gum arabic}.
