Agave hauniensis is a species of plant from the genus of agaves ( Agave ) in the subfamily of the agave family (Agavoideae). The specific epithet hauniensis is derived from the Latin word haunia for 'Copenhagen' and refers to the fact that the plants were cultivated in the local botanical garden.

description

Agave hauniensis reproduces vegetatively through lateral shoots from the rhizome, which is 7 centimeters in diameter . The bent over, linear-lanceolate, somewhat leathery leaves are gently runny. Its point is pointed and has a long, piercing point. The green leaf blade is slightly glauke on the underside and is 49 to 77 (rarely 35 to 92) centimeters long and 4 to 10.5 centimeters wide. The hyaline leaf margins are cartilaginous. They are sometimes dashed in dark green or purple and irregularly serrated to serrated-gnawed. The teeth are small and simple to large and two to three pointed.

The "eared" inflorescence reaches a height of 200 to 350 (rarely up to 380) centimeters. The dense flower-bearing part is 41.5 or more (rarely from 22.5) inches long and carries 23 to 40 or more flowers . The sessile flowers are erect, spread out and fleshy. The ellipsoidal to oval ovary is 12 to 22 millimeters long. The funnel-shaped, almost straight perigone tube has a length of 14 to 20 millimeters. The spread, elongated, hood-shaped, yellowish green or inside also dark red tips are 20 to 27 millimeters (in culture 35 to 46 millimeters) long. The spreading stamens are reddish. The reddish-brown stylus protrudes from the flower tube by 72 to 108 millimeters. The club-shaped scars are triangular. The flowering time is November.

The egg-shaped to elongated fruits , rounded at the bottom, are about 3 centimeters long and 1.2 to 2 centimeters wide.

Systematics and distribution

Agave hauniensis is common in the Mexican states of Guerrero , México and Morelos on lava fields, rocky slopes in oak forests or in clearings in full sun in clearings at altitudes of 700 to 2010 meters.

The first description by Johannes Boye Petersen was published in 1947.

A nomenclature synonym is Manfreda hauniensis (JBPetersen) Verh.-Will. (1978). Further synonyms are Manfreda insignis Matuda (1966) and Manfreda malinaltenangensis Matuda (1976).

The species belongs to the subgenus Manfreda and is assigned to the Manfreda group there.
