Agave neopringlei is a species of agave ( agave ) in the subfamily of the agave family (Agavoideae). The epithet neopringlei honors the American plant breeder and discoverer Cyrus Guernsey Pringle (1838–1911).

description

Agave neopringlei is bare and grows somewhat stem-forming. The trunk, which is often 5 to 6 centimeters long, arises from a narrow, egg-shaped onion . The roots are fleshy. The five to ten leaves (rarely from one leaf) stand together in a basal rosette, or there are one to six additional leaves a few centimeters above the stem base. They are (almost) upright and linearly narrowed. Their leaf blades are 10 to 25 (rarely up to 45) centimeters long and 3 to 7 (rarely 1 to 10) millimeters wide. The leaf margins are somewhat papillary . Occasionally, the foliage leaves are papilous on their underside along the leaf veins.

The "eared" inflorescence reaches a height of 25 to 45 (rarely up to 65) centimeters. The flower-bearing part is 8 to 12 (rarely up to 20) centimeters long and has three to seven flower-bearing nodes arranged in pairs, sitting flowers that are fragrant. The ovary is erect. The tepals are white, sometimes light pink, or white inside and pink outside. The flower tube rising from the base is usually slightly curved outwards in the middle or further down. Below it is slim cylindrical, above it is narrowly funnel-shaped. The flower tube is 30 to 70 millimeters long and measures 2.5 to 4 millimeters in diameter towards the tip. Their tips are almost the same in two rows, ascending and spreading or finally curved back, elliptical to oblong or inverted lanceolate and 10 to 15 (rarely from 5) millimeters long. The dust bag and the pen does not protrude from the flower tube. The stylus has three elliptically elongated or egg-shaped, about 1.5 millimeters large lobes.

The broadly ellipsoidal fruits are 1 to 1.3 inches long and 0.8 to 1 inches wide. They contain seeds 3.5 to 4 millimeters long .

Systematics and distribution

Agave neopringlei is found in the Mexican states of Durango , Nayarit , Aguascalientes , Guanajuato (?), Jalisco , Guerrero , Morelos and San Luis Potosí in grasslands, on grassy clearings and slopes in pine-oak forest areas as well as wet meadows and pastures at altitudes of 800 to 2200 Meters spread.

The first description as Polianthes pringlei by Joseph Nelson Rose was published in 1903. Joachim Thiede and Urs Eggli placed the species in the genus Agave in 1999 . They had to choose a new name because the Agave pringlei Engelm was already a species . ex Orcutt (1883) existed. The name of the herterotypic synonym Polianthes durangensis Rose (1903) could not be used because Howard Scott Gentry had published the first description of Agave durangensis in 1982 .

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