A cultivated species reported from Lahore by Parker (op. cit.). It can be distinguished from other species by its glossy green leaves which are channelled in transverse section. Marginal spines are green, small and sharp. Baker (op. cit.) mentions the marginal spines as brown-black and not green (fide Parker, l.c.).

Agave decipiens might have been introduced from Latin America by Native Americans; it is not otherwise known from the wild. The proliferation of chromosome numbers suggests prolonged human propagation and a probable hybrid origin. Until demonstrated otherwise, the species is considered a rare and localized native species known only from a few sites in southern Florida. H. S. Gentry (1982) discounted the suggestion that A. decipiens was found on the Yucatán peninsula of Mexico. He considered such plants to be A. angustifolia.

Agave decipiens ist eine Pflanzenart aus der Gattung der Agaven (Agave). Ein englischer Trivialname ist „Florida Agave“.
Beschreibung
Agave decipiens wächst einzeln und formt einen Stamm von 1 bis 3 m. Sie bildet Ausläufer. Die variablen, schmalen, fleischigen, lanzettförmigen grünen Blätter sind 75 bis 100 cm lang und 7 bis 10 cm breit. Die Blattränder sind gezahnt. Der dunkelbraune Enddorn ist 1 bis 2 cm lang.
Der rispige Blütenstand wird 3 bis 5 m hoch. Die grünen bis gelben Blüten sind 60 bis 80 mm lang und erscheinen im oberen Bereich des Blütenstandes und reichen bis zur Spitze, an unregelmäßig angeordneten Verzweigungen. Oftmals bilden sich Bulbillen. Die trichterige Blütenröhre ist 11 bis 13 mm lang.
Die elliptische bis längliche dreikammerige Kapselfrüchte sind 35 bis 50 mm lang.
Die Blütezeit reicht von Juni bis Juli.
Die Chromosomenzahl beträgt 2n = 180.[1]
Systematik und Verbreitung
Agave decipiens wächst in Florida in den Vereinigten Staaten in küstennahen Regionen und in Mexiko im Bundesstaat Yucatan.
Die Erstbeschreibung durch John Gilbert Baker ist 1892 veröffentlicht worden.[2] Synonyme sind Agave laxifolia Baker und Agave spiralis Brandegee ex A.Berger.
Agave decipiens ist ein Vertreter der Gruppe Rigidae. Sie ist geographisch isoliert, mit Ausnahme von Agave neclecta. Das von der Halbinsel Yukatan stammende Material, ist wahrscheinlich aus kultivierter Herkunft. Die Blätter werden in nährstoffreichen Böden bis 2 m lang.[3]
Agave decipiens wird im Botanischen Garten Huntington in San Marino in Kalifornien kultiviert.

Agave decipiens, common names false Sisal or Florida agave, is a plant species endemic to coastal Florida in the United States.
Description
Agave decipiens is an arborescent (tree-like) species with a trunk up to 4 m tall, frequently producing suckers (vegetative offshoots). Leaves are frequently 100 cm long, though some of twice that length have been recorded. Leaves have wavy margins with teeth. Flowering stalks are up to 5 m tall, with a large panicle of greenish-yellow flowers. Fruit is a dry capsule up to 5 cm long.[3][4][5][6]
Taxonomy
Some authors have suggested that material from Central America and from the Yucatán Peninsula in Mexico might be of the same species as A. decipiens.[7] Gentry[4] and Zona,[8] however, discounted this possibility, regarding this non-Floridian material as A. vivipara (= A. angustifolia)
Distribution and habitat
Agave decipiens is endemic to Florida. It grows on hummocks in the Everglades and other marshy areas very close to sea level. It is cultivated as an ornamental in other regions.[3][9][10] The species is reported naturalized in Spain, India, Pakistan, and South Africa.[11]

- Kwiaty
- Wyrastają w wiesze na pędzie kwiatonośnym osiągającym 5 m wysokości. Skupione są po kilkanaście i więcej, osiągają 6–8 cm długości, są zielono-żółte[2].
