On sukkot there is a special mitzvah to hold and wave four species, arbat haminim:

פרי הדר – produce of hadar trees, etrog
כפות תמרים –  branches of date palms, lulav
ענף עץ עבות – boughs of leafy trees, hadas (myrtle)
ערבי נחל – willows of the brook, aravot

Jewish communities around the world have always cherished the mitzvah of the four species, arba minim. Many went to great lengths to purchase one etrog for the entire congregation. In past and present, people search for the most beautiful, mehudar, etrog and carefully inspect the arba minim to ensure no blemishes disqualify them.

Over the generations, different traditions have been established regarding these species. Here you will see several types of etrogim used according to the traditions of various communities.

You probably noticed the two palm trees. The one on the right is a regular date palm and is kosher according to all opinions. The one on the left, the canary palm, has inferior fruit and the posekim disagree whether we can use its lulav for the arba minim and if it can be considered kapot temarim, a “date palm.”

Among the three-node myrtles, the hadas meshulash, look out for a special myrtle with nine leaves that emerge from each node.
