(Tosefta): (The Mishnah discussed Baal-Bechi garlic.) What is that? Garlic that has a single row that surrounds the central stalk.

(Rabban Shimon ben Gamliel): Garlic that has only a single layer of peel.

What are onions from Richpa? Any onion whose stem is pressed inside its body.

(Rabban Gamliel): Any onion that doesn't have poison.

Kilkin beans are the square ones.

(Baraisa) (Rabban Shimon ben Gamliel): There's nothing that grows naturally that is square.

Question (R. Barachya) (Mishnah in Maseches Negaim): 'The Baheres blemish itself must be the size of a square Kilki bean'...?

Answer (R. Bisna): On the contrary, the Mishnah itself shows that it's not square, or why would it have mentioned square? Rather, it was to teach that the Kohen should square-off the area when measuring it.

Question: What about 'Nagah' (which is square-shaped)?

Answer: It has many protrusions.

Question: What about 'Anivah D'Pilah'?

Answer: The bottom of it is round.

Some say that R. Shimon ben Gamliel only said it about creatures (but not foods).

Support (Baraisa): Food can be square but creatures cannot.

(Tosefta): 'Egyptian lentils' (listed in our Mishnah) are those that have a sharper edge than other lentils. Rabban Shimon ben Gamliel says that they are any lentils that are not mixed with pebbles (and dirt).

Our Mishnah taught (Bechoros 15) that R. Meir added even Kerikas.) What is Kerikas? They have small stems and any hairs.

What's comparable to it? R. Yosi says - for example, Kunaisa.

Question (R. Yirmiyah): Is there a prohibition of Sefichin on saffron? (Saffron is not edible, so the Kedusha of Sheviis doesn't rest on it, but perhaps Chazal made the prohibition of Sefichin on anything that might be planted in Sheviis...?)

Question (R. Tanchum bar Yirmiyah): But the Mishnah (in Maseches Bechoros 4:8) taught - 'if a person is suspected of transgressing Sheviis, one may not buy even combed flax from him.' Flax isn't food, but it is still prohibited!

Rebuttal (R. Chinana): Flax is different as its seed is edible.

Question (R. Mana): If it's because of its seed, but doesn't the next Mishnah there teach - 'If a person is suspected of selling Terumah as Chulin, one may not even buy from him water and salt.' Could you say that water and salt are prohibited because of their seed?! Rather they are prohibited as a penalty and so too here, the saffron seeds are prohibited, even though they are not edible.

(Menachem bar Mavsima, brother of Yonasan Kippa, citing R. Ami): Flax may be bought from any person in Sheviis.

That applies when it's unknown if the seller is suspected, but if he is certainly suspected, it is prohibited.

(Zuga, the relative of R. Ba bar Zavdi citing R. Abahu): Bikia root (used for dyeing) may be bought from any person in Sheviis. This is when he is unsure if the person is suspected, but if he is certainly suspected, it is prohibited.

(R. Yosi): Our Mishnah does not teach this way - as it says (Bechoros 14(g)), "Seed of the wild Luf, of leek, of onions, of turnip and radishes and other garden seeds that are not eaten (are exempt from Ma'asros and may be bought from anyone in Sheviis)''...

(Baraisa): Seeds of Isatis, Kotzah and Bikia (are also included); implying that Bikia itself may not be bought from just anyone...?

Rebuttal: Perhaps Zuga was referring specifically to when he doesn't know if the person is suspected. But if he is certainly suspected, it would be prohibited to buy.

(When the Mishnah permitted buying wild Luf from anyone in Sheviis) it was specifically referring to wild Luf (but cultivated Luf would be prohibited).

A certain woman had Yarbuzin seeds of Terumah in her box. They fell in a garden and sprouted. She asked R. Yochanan, who permitted the growths.

(R. Chiya bar Vava to R. Yochanan): It's certainly permitted, as our Mishnah taught, "...and even though the seed is Terumah, the plant (that grows from it is not Terumah and) may be eaten.

(R. Yochanan to R. Chiya bar Vava): Oh Babylonian! After I revealed to you the earthenware, you found the jewel (- meaning, after I permitted it and I said the reasoning mentioned in the Mishnah, you then mentioned the Mishnah as a source.)
