A transcription of the 903-name index to Salomon Thomas Nicolai Drejer's Flora Excursoria Hafniensis (Kjøbenhavn, 1838), with a Prolog reading of it. The index interfiles Latin and Danish plant names in one alphabetical sequence and prints no translations; because a plant's Latin and Danish names were set on the same page, the page number works as a join key and part of the pairing is recoverable. The repository also states the five collation rules that recover the printed order, and the eight inversions that remain, one of them by design.
