R' Eliezer ben Yaakov says: A woman who is the daughter of converts may not be married to a Kohen until her mother is of Jewish descent. [This applies to] both converts and freed slaves, and even up to ten generations, until their mother is of Jewish descent.  A guardian, an agent, a slave, a woman, a tumtum, and an androgyne bring but do not read, because they cannot say (Deuteronomy 26:10): "which you have given to me, Hashem."

One who buys two trees within the [property] of his friend brings but does not recite. R' Meir says: He brings and recites.  [If] the spring dried up, [or] the tree was cut down, he brings but does not recite. R' Yehudah says: He brings and reads.  From Shavuos until the Festival of Succos, he brings and recites; from the Festival of Succos until Chanukah, he brings but does not recite. R' Yehudah ben Beseira says: He brings and recites.
