A comprehensive study of 76 species is presented, with detailed descriptions, illustrations, and information on distribution, economic uses, and dialect names. The work includes full synonymy, elaborate identification keys, and detailed plates showing the form of the storage organ, leaves, flowers, and fruits. The plates, created by various artists, are praised for their quality. The book also includes maps indicating geographical distribution and acknowledges financial support from the Bentham-Moxon fund. The book "Theory of Fourier Integrals" by Prof. E. C. Titchmarsh is a well-regarded introduction to the subject. It covers Fourier transforms in the class $ L^{2} $, including Plancherel's theorem, and provides four proofs of this theorem, including one by Wiener using Hermite polynomials. The book also discusses Fourier transforms in $ L^{p} $, the general theory of transforms, conjugate functions, and applications to differential and integral equations. It includes examples of Fourier transform methods in probability and statistical dynamics. The book concludes with a bibliography and is recommended for its thorough treatment of the subject. While primarily aimed at analysts, it may also interest applied mathematicians. The Lebesgue theory of integration is fundamental to the work, and the book includes sufficient examples and applications to illustrate its scope.A comprehensive study of 76 species is presented, with detailed descriptions, illustrations, and information on distribution, economic uses, and dialect names.
