International Association for Plant Taxonomy (IAPT) is collaborating with JSTOR to digitize, preserve and extend access to Taxon. will be cited in synonymy. When a species is moved from one section to another, such transfers are noted under "Observation". For convenience, bibliographic references of omissions, as well as of species described since 1922, are added in the appropriate places. However, no bibliographic references are given for any of the names which can be found readily in Krinzlin's book.During the preparation of this reappraisal it became necessary to make certain nomenclatorial changes. Such changes are found under the following numbers: Subgenus Cyrtochilum 12a, 12b, 58, 74, 76, 98, 103, 115a and Subgenus Oncidium 16b, 91, 204, 213a, 303a.In conclusion it is strongly emphasized that the figure-numbers, given after various specific names, are those published by Krdnzlin within the pages of his monograph. Those drawings are not repeated here. Since many of Krinzlin's drawings are actually copies of the original type-sketches by Reichenbach and Lindley, these are noted at the end of this reappraisal after each name under "Explanation of Illustrations". It should be kept in mind, however, that Krdnzlin was quite careless in copying such fine details as the callosities and serrations, in addition to noting the correct name of the copies. Hence the necessity of re-identifications.
