Source-derived summary

Dudleya abramsii subsp. setchellii, known by common name as the Santa Clara Valley dudleya or Santa Clara Valley liveforever, is a member of the Dudleya genus of succulent perennials, members of the family Crassulaceae. The Santa Clara Valley dudleya, endemic to the Santa Clara Valley region in the southern San Francisco Bay Area, was listed on 3 February 1995, as an endangered species. It is considered to be a subspecies of Dudleya abramsii, but its taxonomic status is still unclear. Its closest relative is Dudleya cymosa subsp. paniculata, which is a morphologically similar sister taxon.

Description

A perennial rosette-forming succulent, this species is characterized by pale yellow petals, a simple (not branching multiple times) inflorescence, and a restriction to serpentine soil.

Morphology

This rosettes are anywhere from 2–9 cm (0.79–3.54 in) wide, on top of stems (also referred to as caudices) that are 10–20 mm (0.39–0.79 in) wide. The stems may branch dichotomously to form 1 to 5 rosettes. The leaves are shaped oblong-triangular to lance-elliptic to lanceolate, and have a glaucous surface.

Editorial summary

Begin with the source’s own compact description: “Dudleya abramsii subsp. setchellii” is species of plant. The dossier treats that line as a proposition to test through Dudleya, abramsii and subsp, not as a finished interpretation.

Editorial reviewUseful for establishing the present vocabulary of the subject while preserving a route back to the evidence on which that vocabulary rests. The current lead gives the account dated anchors—1995—that can be checked directly. The selected authority fields contribute no independent date. For this dossier, Dudleya, abramsii and subsp is the immediate research focus.
Editorial analysis

Why this record matters

The phrase “species of plant” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

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 Jun 20, 2026. The linked authority identifier is Q5312064. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1995.

Critical limits

A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. 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.
