This is one of the scented broomrapes, and we have found it in Crete, Italy and Portugal - so far! To begin with I thought it was Orobanche caryophyllacea (Clove-scented Broomrape), but this does not (according to C.A.J. Kreutz's excellent book on the subject, 'Orobanche - The European broomrape species') occur in Crete. As the broomrape in question definitely smelt of something sweet and flowery, I can only conclude that it is, in fact, Carnation-scented Broomrape - Orobanche crenata - which is also sometimes called Bean Broomrape because it is mainly parasitic on Fabaceae species.

Orobanche crenata grows in a number of other European countries including Spain, France, Turkey and Greece. In Spain this broomrape is a particular problem due to its heavy infestation of Lens culinaris, a lentil crop grown along the Northern coast and in the border areas. It seems likely that it is introduced in the seed used to cultivate the arable fields.
