<big><strong>גמ׳</strong></big> תנו רבנן (ויקרא כג, מ) ענף עץ עבות שענפיו חופין את עצו ואי זה הוא הוי אומר זה הדס ואימא זיתא בעינן עבות וליכא

Gemara. Our Rabbis taught, "Branches of a thick tree" [means] [the kind of tree] whose branches completely cover its trunk Now what [tree] is this? You must say that it is the myrtle (hadas). But perhaps it is the olive? It must be wreathed, but [the olive] is not.
