Sambucus ebulus, dwarf elder, walwort, or danewort, - among the rubbish and ruined foundations of the Priory.

To the Dwarf Elder have been given the names danewort, Danesweed, and Danesblood, probably because it brings about a loss of blood called the "Danes," or perhaps as a corruption of its stated use contra quotidianam.

Now to the Roman standards are they come, And when the chieftain bade the tents be fixed, First all the sandy space within the lines With song they purify and magic words From which all serpents flee: next round the camp In widest circuit from a kindled fire Rise aromatic odours: danewort burns, And juice distils from Syrian galbanum; Then tamarisk and costum, Eastern herbs, Strong panacea mixt with centaury From Thrace, and leaves of fennel feed the flames, And thapsus brought from Eryx: and they burn Larch, southern-wood and antlers of a deer Which lived afar.
