Chamaerops humilis (European Fan Palm)
Family: Arecaceae
Flat, palmately lobed leaves, with deeply bifurcated (split) leaflets. This palm has a leathery joint at base of leaf (hastula--see in picture). Thorns point towards leaves.
Livistona chinensis (Chinese Fan Palm)
Family: Arecaceae
Petiole (stem) extends halfway through leaf, causing a SLIGHT curling. Spines point towards base/trunk of tree
Rhapidophyllum hystrix (Needle Palm)
Family: Arecaceae
Needles at base, very skinny petiole (stem) with no spines. Leaves deeply bifurcated (split) with "hair" on underside of leaf (feels like rough texture)
Rhapis excelsa (Lady Palm)
Family: Arecaceae
Very thin trunks, pink infloresence (blooms) Deeply bifurcated leaves (look like lady fingers cookies...kind of rectangular). Serrated margin

Family: Arecaceae
About 4ft tall. bluish, waxy coating on leaves. Petiole has no spines
Sabal palmetto (Cabbage Palm)
