France. It has also been suggested that our plant may be P. littorale, Link, 
noticed but not described in Schrader’s Bot. Journ. for 1800, page 54, and 
referred by Sprengel to P. flagellare, Bertoloni; but the description given by 
Sebastiani and Mauri in the Prodromus Flore Romane (from Bertoloni’s manu- 
scripts) proves that plant to have woody perennial stems and longish pedun- 
cles, and they quote as a synonym “ P. angustifolium majus," Barr. Obs. 1141. 
ic. 546., which is manifestly a very slight variety of P. maritimum. Gussone 
in his F7. Sicul. Prodr. says, under P. maritimum, “An P. littorale Link En. 
alt. H. Ber. i. p. 385., quod ad P. flagellare adducitur à cl. Spr. in Sy. Veg. ii. 
p. 295. potius P. maritimum varietas est?” l may also add, that P. flagellare 
is not described as a maritime plant, and has, according to Meisner, its fruit 
granulato-striate. It is his var. y. romanum of P. aviculare. Bluff and Fin- 
gerhuth in their Comp. Fl. Germ. i. 500. refer Link's plant to their “ P. avicu- 
lare B. littorale,” and describe it as found “ad litt. mar. baltici”; I should 
suppose that their plant is only the maritime variety of P. aviculare, and that 
their reference to Link is erroneous. Meisner refers this plant to P. mari- 
timum, as a synonym, not even considering it to rank as a variety.
