Source-derived summary

Yucca rupicola is a plant in the family Asparagaceae, known as the twistleaf yucca, twisted-leaf yucca, Texas yucca or twisted-leaf Spanish-dagger. The species was described by George Heinrich Adolf Scheele in 1850. This is a small, acaulescent plant with distinctive twisted leaves. It is native Texas and northeastern Mexico.

Description

Yucca rupicola forms colonies of rosettes, lacking trunks above-ground but producing a branched caudex under the surface. Leaves are narrowly lanceolate, slightly succulent, twisted, up to 60 cm long but about 40 mm wide at its widest point. Flowers are pendant (drooping), bell-shaped, white or greenish, and bloom from April through June. The blooming stalk can measure up to 1.8 m tall (6 feet). Fruit is a dry capsule up to 6 cm long that is dull black in appearance.

Distribution and habitat

Yucca rupicola is native to the Edwards Plateau region of Texas and Coahuila and Nuevo Leon in Mexico.

Editorial summary

The public source identifies “Yucca rupicola” as species of plant. This brief keeps that definition visible, then builds a research path around Yucca, rupicola and species.

Editorial reviewA sound reference starting point where classification, measurement and the date of the underlying evidence remain visible. The current lead gives the account dated anchors—1850—that can be checked directly. The selected authority fields contribute no independent date. Its value is orientation rather than verdict, with Yucca, rupicola and species providing the first useful test.
Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “Yucca rupicola”, the useful work is to connect “species of plant” to the records capable of establishing context and consequence.

Evidence profile

Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Mar 25, 2026. The linked authority identifier is Q2601655. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1850.

Critical limits

Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
