p. iv), Loudon mentioned that the Linnean Arrangement (pp. xxiii-xxiv, 1-466) and its Supplement (pp. 467-490) were entirely the work of Mr. George Don. Loudon (preface
iv, last paragraph- lines 1-5) mentioned: No further explanation appearing necessary in this Preface, it remains for the Editor to state that the Linnean Arrangement and its Supplement are entirely the work of Mr. George Don; the Natural Arrangement is founded on that of Professor Lindley, with some additions and alterations rendered necessary by the plan of this Catalogue; and Dr. Greville, the profound cryptogamist, assisted in arranging the Cryptogàmia."
