Dudleya linearis
species of plant
Dudleya linearis is an insular succulent plant known by common name as the San Benitos liveforever. It is a rosette-forming perennial characterized by its long, flat green leaves on clustered heads and its yellow flowers. It is endemic to the western island of the Islas San Benito, a small Mexican archipelago in the Pacific Ocean west of Cedros Island. The limited population of the species is vulnerable, and has twice come close to extinction from introductions of grazing animals.
Description
Dudleya linearis is a succulent perennial with long, flat green leaves in clustered rosettes and distinctive yellow flowers from March to May. The chromosome number is n=17, the base number for Dudleya.
Reid Moran noted that Dudleya linearis closely resembles, in vegetative form, Dudleya guadalupensis, endemic to Guadalupe Island to the northwest, based on their long, flat green leaves. The two can be separated by their significantly different inflorescences and flowers. Plants of Dudleya albiflora on Cedros Island have also been historically confused with this species.
Morphology
The caudices are caespitose, branching apically.
This brief starts where responsible research should: with the source description of “Dudleya linearis” as species of plant. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as species of plant. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Jan 6, 2026. The linked authority identifier is Q15500524.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. 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.
