Agave ovatifolia is a plant from the genus of the Agave ( agave ). An English common name is "Whale's Tongue Agave".

description

Agave ovatifolia grows solitary with a height of 60 to 90 cm and is 80 to 120 cm wide. The bluish to gray, variably arranged, stiff, strong, broad elliptical to oval-shaped leaves are 35 to 4 cm long and 20 to 24 cm wide. The leaf margins are serrated irregularly. The dark gray to black variable pointed to blunt end mandrel is 2 to 3 cm long.

The paniculate, straight to slightly curved inflorescence is 3.5 to 4 m high. The green to yellow colored, numerous flowers appear in the middle to the upper half of the inflorescence at the end of the loosely arranged, variable branches and are 65 to 75 mm long. The flower tube is 15 to 20 mm long.

The elongated three-chamber capsule fruits are 50 to 60 mm long and 15 to 20 mm wide. The shiny, black, moon-shaped seeds are 5 to 6 mm long and 3 to 4 mm wide.

Systematics and distribution

Agave ovatifolium grows endemically in Mexico in the states of Nuevo León in limestone soils, on stony slopes, in forest and grassland at an altitude of 1100 to 1300 m. It is associated with Agave asperrima , Yucca rostrata , Dasylirion species, Ferocactus hamatacanthus and other cacti and succulent species.

The first description by Gregory Dirk Starr and José Angel Villarreal-Quintanilla was published in 2002.

Agave ovatifolia is a member of the Parryanae group and grows endemically in the Sierra de Lampazos in northern Nuevo Leon in Mexico. Plants were first found by Nickels (1870) and known as Agave Noah . Trelease (1911) classified this illegally described species as a synonym of Agave wislizenii Engelmann. Characteristic are the compact, more open rosettes with the bluish to gray, variably arranged, stiff, strong, broad elliptical to oval-shaped leaves. The leaf margins are serrated irregularly. The dark gray to black pointed to blunt end mandrel is 2 to 3 cm long.

Agave ovatifolia is closely related to Agave havardiana and Agave parasana , the other representatives of the Parryanae group, but the differences in size, leaf and flower structure are recognizable.

Agave ovatifolia can withstand short periods of frost down to minus 10 ° C when it is dry.
