Source-derived summary

Dudleya lanceolata is a succulent plant known by the common name lanceleaf liveforever or lance-leaved dudleya. It is an extremely variable and widely ranging species that occurs from Monterey County and Kern County in California south through Ensenada in Baja California. It is characterized by green to purple lanceolate leaves, red, orange, or less commonly yellow petals, and is typically tetraploid. Despite its diversity, it is quite stable as a species, but hybrids may be discovered with other species of Dudleya, which can make it difficult to discern in areas where numerous species converge.

Description

Vegetative morphology

This plant is a rosette-forming succulent. The rosettes emerge from the apex of the caudex, which may be solitary or apically branched, with anywhere from 1 to 7 rosettes on top. The caudex is 1 to 3 cm wide, less than 4 cm long, but is occasionally elongated. The rosettes are 3 to 25 cm in diameter, and typically with 10 to 25 leaves. The leaves are green and sometimes glaucous, but not farinose, shaped oblong to lanceolate, 4 to 30 cm long by 0.5 to 4 cm wide, and 1.5 to 6 mm thick. The tip of the leaf is acute.

Editorial summary

“Dudleya lanceolata” enters the record as species of plant. Crown Archives preserves that source wording while asking what Dudleya, lanceolata and species can confirm, complicate or overturn.

Editorial reviewA practical orientation to terminology and classification, particularly when read beside dated observations, specimens or technical literature. The current 199-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. Its strongest next move is a source search built around Dudleya, lanceolata and species.
Editorial analysis

Why this record matters

“Dudleya lanceolata” is worth following because a concise public description often conceals a longer documentary argument. Here, Dudleya, lanceolata and species provides the most credible route into that argument.

Evidence profile

The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Jun 29, 2025. The linked authority identifier is Q5312059. None of the 0 selected statements returned an explicit reference.

Critical limits

Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. 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.
