Most dals are beans or peas*, but are called, for unknown reasons, lentils ;D
Haha, wish I could! (: They look similiar to the leaves, so you're talking about a pea with pod and everything? The seeds do remind me of whole urad, though. Also called "black lentils". (here again - no real lentil, haha)
Mysore sounds very nice, btw (:
