Agave maculosa is a species of agave ( agave ) in the subfamily of agave plants (Agavoideae). The specific epithet maculosa comes from Latin , means 'speckled' and refers to the marbled leaves.

description

Agave maculosa grows with upright, arched, linear-lanceolate leaves that are deeply rutted. The dark green leaf blade is 14 to 44 centimeters long and 1.2 to 2.7 centimeters (in culture up to 3.9 centimeters) wide. It is unspotted or covered with lighter green and brown or green spots. The spots are round to elliptical and sometimes glaucous . The edges of the leaf are usually small, spaced apart teeth.

The "eared" inflorescence reaches a height of 60 to 140 centimeters (in culture of up to 180 centimeters). The flower-bearing part is 14 to 22 (rarely 7.5 to 29) centimeters long (in culture up to 48 centimeters) and bears seven to 29 (rarely up to 41) spread flowers . The ovary is 9 to 16 (rarely up to 19) millimeters long. The perigon tube has a length of 6 to 16 millimeters. Their inside yellow-green or mahogany-brown perigone lobes are 9 to 13 (rarely 6 to 16) millimeters long. The stylus is up to 4 millimeters longer or up to 10 millimeters shorter than the perigone tube.

The spherical to elongated fruits are 1.6 to 1.9 (rarely up to 2.5) centimeters long and 1.3 to 1.6 centimeters wide. They contain seeds 4 to 5 millimeters long and 3 to 4 millimeters wide.

Systematics and distribution

Agave maculosa is found in the United States in the south of the state of Texas and in the Mexican states of Nuevo León , Hidalgo , Puebla , San Luis Potosí , Tamaulipas and Veracruz in dry chaparral , on slopes or between rocks, but also in moist oak forests at altitudes of 10 Widespread up to 1830 meters.

The first description by William Jackson Hooker was published in 1859.

Nomenclatory synonyms are Manfreda maculosa (Hook.) Rose (1903) and Polianthes maculosa (Hook.) Shinners (1966). Further synonyms are Agave maculata Engelm. ex Torrey (1859, nom. illeg. ICBN -Article 53.1), Agave maculosa var. minor Jacobi (1868), Agave maculosa var. brevituba Engelm. (1875) and Agave maculata var. Brevituba (Engelm.) Mulford (1896, incorrect name ICBN -Article 11.4)

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