description
Nolina lindheimeriana grows without a trunk and forms clumps 1 to 2 m in diameter. The variable, grass-like, green to yellow leaves that fall to the ground are 30 to 100 cm long and 3 to 12 mm wide. The leaf margins are serrated.
The branched inflorescence becomes 1 to 2 m long. The yellow to cream-colored flowers are 1.8 to 2.5 mm long and wide. The flowering period extends from April to May.
The woody capsule fruits, which are slightly squeezed to round when ripe, are 7 to 10 mm in diameter. The brown, spherical seeds are 2 to 3 mm in diameter. The seeds ripen in July.
Nolina lindheimeriana is frost hardy to minus 12 ° C. It is hardly known in Europe.
Distribution, systematics and endangerment
Nolina lindheimeriana is common in the US state of Texas and in Mexico in the state of Zacatecas in a limited area at altitudes of 400 to 600 m, where it grows on limestone hills and in open woodland. It is associated with Yucca rupicola , the natural hybrid Yucca × keithii and various Opuntia species.
It was first described as Dasylirion lindheimerianum in 1853 by George Heinrich Adolf Scheele . Sereno Watson placed it in the genus Nolina in 1879 . A synonym is Beaucarnea lindheimeriana (Scheele) Baker .
It is similar to Nolina texana , a representative of the Erumpentes section , but has differences in inflorescence and leaf structure.
Nolina lindheimeriana is endangered by new settlements.
