' preface to the Viridarium the following explanation of the relation- 
ship between the two works: | 
" Nomina quibus enumerantur plantae mutuata sunt ex Horto 
Cliffortiano fere omnia (paucis emendatioribus), singulis adjecto duplici 
numero, quorum priore paginam Horti Tui indicavi, posteriore vero 
generis speciem, ut si quae differentia minus indubitata occurreret, in 
majori opere eo facilius consulerentur synonyma. ” 1 
-It is therefore clear that the following accounts, with the exception 
of the synonymy which is quoted in the Hortus, refer to the same plant.

The third polynomial quoted by Linnaeus in the Species Plantarum, 
Lysimachia lutea corniculata Bauhin, has not been satisfactorily iden- 
tified by recent authors? Nevertheless Bauhin's description is a 
lengthy one, and, for his time remarkably satisfactory, so that it is 
1 *''The names by which the plants are enumerated are almost all taken from the 
Hortus Cliffortianus, a few having been somewhat improved and to each having been 
added a duplex number, by the first part of which I have indicated the page of your 
Hortus and by the last the species of the genus, so that if any somewhat doubtful 
distinction should present itself, the synonyms of the larger work might be the more 
readily consulted.” 
? Dr. R. R. Gates at one time attempted to identify Lysimachia lutea corniculata 
with what we now know as Oenothera Lamarckiana. See the following papers:
