Populus angustifolia is a tree that is native to California, and also found elsewhere in North America and beyond.
California Rare Plant Rank: 2B.2 (rare, threatened, or endangered in CA; common elsewhere).
[Wikipedia] Taxonomy: Where their ranges come into contact, this species will readily hybridize with Populus balsamifera, Populus deltoides, Populus fremontii, and Populus trichocarpa. These hybrids can form extensive populations in some regions. Due to the frequency and morphological consistency of P. angustifolia × P. deltoides hybrids, they were initially described as a fully separate species ("P. acuminata") until its hybrid origin was firmly established in the 1980s.
