Agave jaliscana is a species of agave ( Agave ) in the subfamily of the agave family (Agavoideae). The specific epithet jaliscana comes from Latin and refers to the occurrence of the species in the Mexican state of Jalisco .
description
Agave jaliscana grows solitary or with many heads with semi-fleshy roots . Storage rhizomes are elongated and measure 1.3 to 2.2 centimeters in diameter, spread rhizomes are cylindrical. The five to ten spread out, linear, herbaceous leaves are runny. Its point is pointed and has a short point. The tiny scattered papillate , green, not spotted leaf blade is 49 to 78 (rarely up to 93) centimeters long and 0.6 to 1.4 (rarely up to 2.8) centimeters wide. The leaf margins show very narrow, hyaline bands and are occasionally tiny papillate. The remnants of the leaf base disintegrate into 4 to 7 centimeters long stiff fibers.
The "eared" inflorescence reaches a height of 100 to 155 centimeters. The elongated, semi-dense flower-bearing part is 11 to 38 (rarely up to 42) centimeters long and has eleven to 40 sessile or sometimes short-stalked flowers . Fully grown flowers are almost upright. The narrow ellipsoidal ovary is 8 to 13 (rarely 6 to 16) millimeters long and has a neck. The narrow, funnel-shaped, straight perigone tube is slightly constricted above the ovary. It has a length of 4 to 10 millimeters. The elongated, narrow and bent back tips are 9 to 17 millimeters long. The stylus rises above the flower tube by 62 to 84 (rarely 56 to 98) millimeters. The club-shaped scars are triangular and deeply grooved. The flowering period extends from early November to early April.
The spherical to elongated fruits are 1.1 to 2.7 inches long and 1.2 to 1.7 inches wide. They contain seeds 3 to 4 millimeters long and 4 to 5 millimeters wide.
Systematics and distribution
Agave jaliscana is common in the Mexican states of Sonora , Jalisco and Michoacán on loose, black clay or rocks, in pine-oak forests and on grassy slopes.
The first description as Manfreda jaliscana by Joseph Nelson Rose was published in 1903. Alwin Berger placed the species in the genus Agave in 1915 . A nomenclature synonym is Polianthes jaliscana (Rose) Shinners (1966).
The species belongs to the subgenus Manfreda and is assigned to the Manfreda group there.
