Distribution
Peraphyllum ramosissimum grows in 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.
Description
Peraphyllum ramosissimum is a shrub which may reach 3 metres (9.8 ft) in height and bears small pomes about 1 centimetre (0.39 in) wide. The leaves are simple; they can grow very close together on short shoots but are well separated on longer shoots.[2]
