| The plants of the palmae family are unique in that the leaves are very closely spirally arranged. The palms introduced here have leaf blades that are fan-like. The segments of each blade as it emerges from the bud are very tightly folded. By the time the blade has emerged from the bud, the segments have unfolded and fanned out. 3 species of palms are introduced here. |

saw palmetto |
Saw palmetto is usually a horizontal plant. It branches beneath
the soil surface or it runs more or less along the surface. The leafy
extremities of the branches are at or just beneath the surface. It
commonly forms low thickets. In some places it occurs in intricate
systems of more or less continuous colonies. Thickets can reach a
height of 9-10 feet.
Each leaf is quite long, each petiole reaching 3 feet in length or more. Leaf petioles have 2 sharply serrated, sawteeth-like edges, thus the name of the plant. The leaf blades are palmate, with 30 or more segments which fan out from the palman (undivided section of the leaf). The hastula (a protuberance of the petiole at the base of the blade) occurs on both sides of the leaf blade and does not extend over the leaf blade. This is an important distinguishing characteristic of this genus. Flowers
Fruit
Habitat Saw palmetto occurs in a variety of habitats. It is often abundant
in both well-drained and poorly-drained pine flatwoods. It also grows
on deep sands of longleaf pine-scrub oak ridges and hills. It is
found on the coastal plain from South Carolina to the Florida Keys; west
to Louisiana.
The drupe contains a compound that has been shown to reduce the effects
of prostrate cancer.

cabbage palm |
Habit
The cabbage palm is a tree, reaching 60-80 feet in height, 1-2 feet
in diameter. Numerous dead leaves oftem hang, skirting the trunk
beneath the crown of living leaves. The leaf bases usually persist
for several years before crumbling and falling away. This tree is
the State Tree of Florida.
There are usually about 40 living leaves on well-developed crowns. Each leaf petiole is quite long and very stout, reaching 4-5 feet in length and 1-2 inches wide. Leaf petioles are usually longer than the blades. Leaf bases split as they expand, forming a v-shaped gap. The hastula (a protuberance of the petiole at the base of the blade) prominently extends over the leaf base of the blade. The hastula is very thick and rigid. The leaf blades are palmate, with 40-90 or more segments. Each mature leaf blade is 3-4 feet in length and about 5 feet wide. Flowers
Habitat The cabbage palm occurs principally near the coasts, on tidal flats, islands, or elevated places in marshes, beach swales, and in moist to wet hardwood hammocks. It is found from southeastern North Carolina to southern Florida; also on the Bahaman Islands. Use This tree is commonly used as an ornamental.

scrub palmetto |
| Habit
The scrub palm is a ground shrub with an S-shaped or contorted subterranean stem. The crown bud is held well below the soil surface. There are few leaves per crown, 5-10 living leaves at a given time.
Petioles are 6-12 inches long, 1/4-1 inch wide. The hastula extends
over the base of the leaf. Leaf blades are much smaller than those
of the cabbage palm.
Fruit
Habitat The scrub palm inhabits sand pine-oak scrub and dune scrub in Florida.
