{Pesachim 31a continues}
{money} to an Israelite on his {=the Israelite's} chametz, after Pesach it is permitted in benefit":
{Pesachim 31b}
{The case is} Such that he deposited with him {the gentile} and said to him, "acquire it for yourself from now if I do not bring you the money from now until day X," and if he does not say "acquire it from now," the gentile does not acquire it, and it stands in the possession of the Israelite, and is forbidden. And so is the halacha.

"Chametz upon which ruins collapsed are regarded as if removed":
Rav Chisda said: And he needs to annul it in his heart.

"Rabban Shimon ben Gamliel says: Anything that a dog cannot search after it":
A Tanna taught: And how far is the searching of a dog? Three handbreadths.

{Pesachim 35a}
Mishna:
These are the things with which a man may fulfill his obligation {of eating matzah} on Pesach: With wheat, with barley, with spelt, with rye, and with oats.
{The continuation of the Mishna follows the same list given in Eruvin 31a for what may be used to make an eruv}
And they may fullfill with demai {produce where we are unsure that maaser has been taken off}, and with maaser rishon from which teruma {=terumat maaser} had been taken off, and from maaser sheni and hekdesh which had been redeemed; and the Kohanim with challah and teruma. But not with tevel, nor with maaser rishon from which teruma had not been taken off, nor with maaser rishon or hekdesh that had not been redeemed.

The loaves of the thanksgiving offering and the wafers of a nazir, if he made them for himself he may not fulfill {his obligation} with them. If he made them to sell in the market, he may fulfill {his obligation} with them.

Gemara:
A Tanna taught: Kusmin {Spelt} is a type of wheat. Shibolet Shual {translated here as oats} and shifon {rye} are types of barley. Kusmin is gulfa {our gemara: gulba}, shifon is dishra, shibolet shual is shibolei taala {=foxears}. {The preceding was just a listing of the Aramaic names for the grains.}

These, yes.
