[Avodah] Are emmer, einkorn and durum wheat?

[Danny Schoemann]

Somebody asked me:

"I have a question in Halocho. We all know that there are 5 species of
Dagan that have special laws such as Hamotzi, Chometz, etc..

But from the scientific point of view there have been and still are
several other domesticated Deganim. For example: emmer, einkorn,
durum. These species are distinct. They are not a variation of one of
the 5 species. So legally they are not. But practically they contain
gluten and they undergo the same Chimutz during Pessach.

So my questions are:

how are they treated during Pessach?

how are they treated for the purpose of blessings??"

Based on what Wikipedia says, I would guess they are halachically
wheat. R' Wiki even calls them emmer wheat, einkorn wheat , durum
wheat. At http://en.wikipedia.org/wiki/Matzo they even say:

"As more accurate historic and botanical evidence comes to light, some
scholars today propose that only the 'five grain species' native to
the Land of Israel can become chametz.[4][5] They are:
 1.Chittah – durum wheat (T. durum),
 2.Se’orah – barley - 2 row (Hordeum vulgare), and
 3.Kusmin - emmer wheat (T. dicoccon),
 4.Shiphon - einkorn wheat (T. monococcum),
 5.Shibbolet – barley – 6 row (Hordeum vulgare)"


Anybody have something concrete on this from classical sources"?
