Publisher's Synopsis
Excerpt from A Revision of the Genus Polygala in Mexico, Central America, and the West Indies
A new epoch in the study of the genus Polygala was initiated by the appearance of Chodat's monograph in 1893. Here the species of the world, some 405 in number (of which some 57 were recorded from Mexico, Central America, and the West Indies), were divided into ten well-marked sections, and the great value of the characters to be derived from the persistence or deciduousness of sepals and wings, the nature of aril, capsule, and style, and the clothing of the seed, received due recognition and illustration. Unfortunately this work, on which all future taxonomic study of the genus must be based, is marred by many typographical and other inaccuracies. One finds two new species described under the same name, and even two consecutive valid species maintained with the same trivial; un fortunate errors of geography, of author-citation, and of nomen clature omission of mention of species described in easily accessible works; and keys so loosely drawn up as to be frequently mislead ing. All these faults, however, cannot obscure the real worth of Chodat's monograph, which in its main lines is thoroughly sound, and from its wealth of illustration must always remain an indis pensible work of reference.
