What is dafin?
Dafin is Bulgarian (I was born in Sofia) for laurel, or bay leaf. An evergreen shrub, of the genus Laurus (L. nobilis), having aromatic leaves of a lanceolate shape, with clusters of small, yellowish white flowers in their axils ; called also sweet bay. The fruit is a purple berry.
It is found about the Mediterranean, and was early used by the ancient Greeks to crown the victor in the games of Apollo. At a later period, academic honors were indicated by a crown of laurel, with the fruit. The leaves and tree yield an aromatic oil, used to flavor the bay water of commerce. [source]
What Else?
Well, in Arabic (Al-) Dafin describes the burial process for the deceased at the cemetery, hmm... rather macabre, anyway for more information than you ever want to know on the use of 'Dafin' leafs in the past and today go here.
