humous publication by his son (De plantis exoticis libri duo. 
Venice. 1627), so that he could not have written this in 1621 or 
1622, nor sent seeds to BAUHIN in 1619. Born near Venice, 
ALPINUS became professor of botany in the University of Padua in 
1593, and, if not then, somewhere between that time and 1617, 
the date of his death,t became director (praefectus) of the botanic 
garden at Padua. 
Though BAUHIN could not have obtained the seed from ALPINUS 
in 1619, we are not devoid of a clue to the garden at Padua. Fortu- 
nately, among other sources for his Pinax which BAUHIN gives, is 
a preliminary page with the heading Nomina eorum qui plantas vel 
semina communicarunt. Three of these were connected with 
the garden at Padua. The dates are not given, but the order of 
succession places them: (1) “JAcopus ANTONIUS CoRTUSUS, 
quintus Patavini horti praefectus’”’; (2) ‘“PRosPER ALPINUS, 
Profess. et horti Patavini sextus praefectus”’; (3) “JoAN. PRE- 
vortius, Med. Professor et horti Patavini septimus praefectus.” 
The succession being without a break, and the time being so short 
between the death of Atprnus and the reception of the seed by 
BAUHIN in 1619, taken in connection with his full and careful 
record of sources, leaves little room for doubt that they were 
obtained from Prevortius, the seventh director of the garden. 
There is, however, a very narrow interval between the commonly 
accepted date of introduction from America and the death of 
ALPINUS (1617), in which he states that he raised plants from seeds 
obtained from Dr. More. For the ‘‘two years ago” (“ob hinc 
duos annos”’) refers evidently to the time when the plants came up 
and not to the date of reception. Two years had elapsed between 
the appearance of the plants and the writing of the account. It 
would be necessary to place the date of introduction as early as 
1614 at least. The figure of the plant in the work of ALPINus, 
therefore, must be a representation of one almost at the beginning 
of its appearance in Europe. Dr CANDOLLE, comparing the figures 
of Lysimachia lutea siliquosa virginiana given by PARKINSON in 
his earliest work (Paradisus, 1629) and in his second work (Theat-
