Tosefta על ברכות 80:21

Rabbi Yosei son of [Rabbi] Yehuda says, moist [i.e., fresh] dates are exempt from Peah, because the first one does not wait for the last ones (see Y. Peah III.1.10). Rabbi Eliezer son of [Rabbi] Tzadok says, the jujube is liable in Peah. Others say, even benot shuach (translation uncertain, see Ber. 40b:21).
