description
Dasylirion simplex grows stemless and forms groups with narrow rosettes. The variable, green, smooth, serrated leaves are 50 to 120 cm long and 6 to 12 mm wide. The tips are fibrous in the juvenile stage.
The panicley, narrow inflorescence becomes 1 to 2 m high. The flowers are white to cream in color. The flowering period extends from July to August.
The egg-shaped capsule fruits contain one or two seeds and are 6 to 8 mm long and 6 to 12 mm wide. The triangular seeds are 3.5 mm long and 2.5 mm wide.
Dasylirion simplex can withstand short periods of frost down to minus 8 ° C.
Distribution and systematics
Dasylirion simplex occurs in Mexico in the state of Durango at 1800–2100 m altitude and is rare. It grows in a gritty, calcareous substrate, associated with Yucca decipiens , Nolina durangensis and various Opuntia species.
It was first described in 1911 by William Trelease .
Dasylirion simplex is a member of the Dasylirion section . It forms clumps with small rosettes and smooth, toothed leaves. The fibrous end tips are typical in the juvenile stage. It is closely related to Dasylirion durangense , a member of the Glaucophyllum section , but there are clear differences in the leaf structure (waxy).
Dasylirion simplex is rarely found in culture.
