Palm “Streamers”?

Recommended Posts

Dadpool

We live in west central Florida and have several Foxtail palms and Christmas tree palms. In the last week or two we have noticed that some of the fronds on both species have a long streamer like projection that thicker than the leaves on the frond, is three feet longish and is about 1/4 inch wide and is jagged. Anyone know what this is? Thanks!

They're called 'reins'.

@Dadpool Welcome to the forums!  You'll notice the same on Veitchia arecina as well.

 While my friends have answered your question as to what they are and shown an excellent example, I'll elaborate a little on where those reins originated with a few photos.  They are essentially part of the emerging spear that has stuck to the leaflet tips as they separate.  The first photo shows a fine connector piece on a Cyphosperm balansae, which on my small plant falls off without leaving any dangling reins.  Second shot shows reins forming as leaflets separate on a newly emerging Dypsis prestoniana leaf.  Third shows the retained reins which hang down from another Dypsis prestoniana.  Final shot shows how the reins on a Howea belmoreana are actually still connected to the emerging spear that the new leaf is still splitting off from, with it connecting to the older spear's emerging leaflets.  Some species won't retain reins, while others will hold them for the duration of the frond's life, usually connected to the most basal leaflet.
