Was this among The Palm Facts you knew?

Palm Fronds Definition

Simply put the definition of a palm frond, is a palm tree leaf. But there are different types.

PINNATE LEAVES - This type of palm frond is probably the more common of the two frond types. Pinnate frond is the scientific name.

But it's often called a Feather Palm. As you may have noticed, it has this nickname because the structure is reminiscent of a bird's feather.

PALMATE LEAVES - This type of palm frond is quite popular. Palmate Frond is the scientific name.

Much of the time it's referred to as a Fan Palm. One reason is it does look like a fan. The type of hand-held fan you unfold, to fan your face on a hot day!

Yet, it's also suggestive of the palm of your hand. That's likely where its scientific name originated. Put up you hand with your fingers straight up, and it's similar in shape to a Palmate Frond.

Do these shapes remind you of palm fronds?

Explaining Parts of the Palm Leaf

EASIEST PARTS TO KNOW

First thing is knowing that all types of palm leaves have specific parts of a palm frond in common. They have certain main forms found in them all.

THREE COMMON PARTS TO ALL PALM FRONDS

SHEATH:

Also sometimes called the Leaf Base. It has tough inner fibers that help the frond avoid damage. Kind-of like "crazy gluing it" - by anchoring the leaf to the trunk. This gives it stability & support through windy times. 

STEM:

Scientifically called the petiole. It connects the green blade of the leaf to the trunk or branch of the palm. Acting like the frond's support beam. It gets water & nutrients coming up from the roots to the frond's blade.

The petioles of some species have thorns. They're called spines when they're on palms.

BLADE:

It's what you typically think of as the leaf part of a palm frond. It's the expanded greenish area. Also called the lamina.

Most are divided into those two common types of leaves: Fan (palmate) or Feather (pinnate). 

They capture sunlight for the process of photosynthesis. Which changes light energy with the air's CO2 into food the palm needs.

Because Some Pinnates Have Secondary Rachis

RACHIS:

The central supporting vein or stem of the pinnate frond. Technically that comes off of, or it's an extension of the petiole. It supports the structure of the leaf or frond. It also continues bringing water to the frond's green mass to support food production.

PINNAE:

Often called leaflets. The smaller leaves within the blade of a pinnate frond. They attach to the rachis. If you refer to a single leaflet, the term is pinna.

PETIOLE: 

This part of a palmate frond ends where the blade begins its expansion. In some species a small knob called a hastula is at the petiole's end. That's helpful for palm tree identification, sorting out one from another.

Another thing to note. In some species, the petiole actually extends into the blade to varying degrees. These are called Costapalmate Fronds.

SEGMENT:

The ending tip of the blade. From where it divides from the main part of the blade.
