Dudleya cymosa subsp. pumila
subspecies of plant
Dudleya cymosa subsp. pumila, most commonly known as the low canyon dudleya, chalky canyon dudleya or California live-forever, is a species of perennial succulent plant. It has diamond to spoon shaped leaves, sometimes coated with a fine white powder, and in May through July, bright red, orange or yellow flowers adorn the short inflorescence. A leaf succulent primarily found growing in rocky cliffs and slopes, it is endemic to California, and grows in the Transverse Ranges and South Coast Ranges, with some outlying populations. A variable plant, in some localities it is difficult to distinguish from other plants in the genus.
Description
The plant has diamond to spoon shaped leaves, with a height of 5 to 15 cm, and reddish-orange or yellow flowers.
Vegetative morphology
The stem is typically 1 to 2 cm wide, crowned by an apical rosette. The rosettes are often solitary, although some plants may have branching stems with 2-5 rosettes. Each rosette is 4 to 10 cm wide, with 10 to 25 leaves. The leaves are green, and some are glaucous or even farinose, although few are green in times of drought.
This brief starts where responsible research should: with the source description of “Dudleya cymosa subsp. pumila” as subspecies 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 subspecies of plant. Its deeper value depends on whether names, dates, institutions and citations support that framing.
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 Aug 4, 2025. The linked authority identifier is Q24688569. None of the 0 selected statements returned an explicit reference.
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
