Td puxpdv has just as little to be said for it as that suggested by 
Amatus. ough the account which Dioscorides gave of 
pexpov is much shorter than that given of To peya, there is 
nothing in what Dioscorides has said which is inconsistent with 
fact that the account of Td puxpov is so brief, instead of justi- 
fine scholars, from the X VIith Century onwards; i in treating the 
nts as members of different natural families, suggests the 
li 
give oxopmiovpoy as a synonym of To pixpov as well as of Td péya. 
No doubt all four may be due to some error on the part o 
copyists; on the other hand, all four may equally well indicate 
that early students of Dioscorides were aware that’ 7d uLKpov, 
like to wéya, has an inflorescence ‘ curved like the tail of a 
scorpion.” That the latter is the more probable ec cuek ae is 
indicated by the fact that the great Vienna Codex supplies a 
portrait of Td jeKxpov which, although somewhat crude, un- 
doubtedly lepine & oe species we now know as Heliotropium supr- 
num, Linn, (Sp. Pl. p. 180).

t will be noted that in the ‘Pflanzenreich ’ Pax and Hoffman,
