EspañolSERENOA
(Redirected from Saw Palmetto)
'''Serenoa repens''', the 'saw palmetto', is the sole species currently classified in the genus '''Serenoa'''. It has been known by a number of synonyms, including ''Sabal serrulatum'', under which name it still often appears in alternative medicine. It is a small palm, normally reaching a height of around 2-4 m. Its trunk is sprawling, and it grows in clumps or dense thickets in sandy coastal lands or as undergrowth in pine woods or hardwood hammocks. Erect stems or trunks are rarely produced but are found in some populations. It is endemic to the southeastern United States, most commonly along the Atlantic and Gulf coastal plains, but also as far inland as southern Arkansas. It is extremely slow growing, and long lived, with some plants, especially in Florida, being over 700 years old.
Saw palmetto is a fan palm (Arecaceae tribe Corypheae), with the leaves with a bare petiole terminating in a rounded fan of about 20 leaflets. The petiole is armed with fine, sharp teeth or spines that give the species its common name. The leaves are light green inland, and silvery-white in coastal regions. The leaves are 1-2 m in length, the leaflets 50-100 cm long. They are similar to the leaves of the palmettos of genus ''Sabal''. The flowers are yellowish-white, about 5 mm across, produced in dense compound panicles up to 60 cm long. The fruit is a large reddish-black drupe and is an important food source for wildlife. The plant is used as a food plant by the larvae of some Lepidoptera species including ''Batrachedra decoctor'' (which feeds exclusively on the plant).
The genus name honors American botanist Sereno Watson.

The fruits of the saw palmetto are highly enriched with fatty acids and phytosterols, and extracts of the fruits have been the subject of intensive research for the treatment of urinary tract infections.
