Peraphyllum
genus of plants

Peraphyllum is a monotypic genus of flowering plants in the rose family, containing the single species Peraphyllum ramosissimum, commonly known as wild crab apple.
Description
Peraphyllum ramosissimum is a shrub which may reach 3 metres (10 ft) in height. Growing up to 3.5 centimetres (1+1⁄2 in) long, the leaves are simple; they can grow very close together on short shoots but are well separated on longer shoots.
Like most other flowering plants of the Rosaceae, P. ramosissimum has 5 petals and 5 sepals with radial symmetry. The flowers have about 15–20 free stamens, and the petals are white to rose in color. The fruit is a yellowish to purplish pome about 1 centimetre (1⁄2 in) wide.
Taxonomy
Translated from the Greek, the genus Peraphyllum means "very leafy" and the species name ramosissimum means "many branches". Peraphyllum is most closely related to Amelanchier, Malacomeles, Crataegus, and Mespilus.
Distribution and habitat
Peraphyllum ramosissimum grows in Washington, California, Oregon, Idaho, Utah, Colorado, and New Mexico, usually in pine and juniper woodlands. In California it can be found in the High Cascades, High Sierra Nevada, Great Basin, and Mojave Desert sky islands.
The public source identifies “Peraphyllum” as genus of plants. This brief keeps that definition visible, then builds a research path around Peraphyllum, genus and plants.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Peraphyllum”, the useful work is to connect “genus of plants” to the records capable of establishing context and consequence.
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 Mar 21, 2026. The linked authority identifier is Q3487167. 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
