Populus nigra L.
Habit: Tree < 20 m; crown wide or slender. Stem: twigs yellow-brown, winter buds red-brown. Leaf: petiole 1/3--2/3 blade; blade 3--5 cm, deltate to rhomboid, glabrous, adaxially green, base +- truncate to tapered, tip acute, margin crenate to serrate.
Ecology: Disturbed places near settlements; Elevation: 600--1800 m. Bioregional Distribution: SnFrB, SCo, SNE, DMoj, expected elsewhere; Distribution Outside California: native to Europe. Flowering Time: Feb--May
Unabridged Synonyms: Populus nigra var. italica Du Roi
Unabridged Note: Plants with slender crowns are called Lombardy Poplar, but they all have been propagated from a single clone and therefore are not worthy of formal taxonomic recognition, so that the scientific name that has been applied to them (Populus nigra L. var. italica Du Roi) is to be treated as a synonym, as is Populus nigra L. var. nigra, which refers to plants with wide crowns that are called Black Poplar. Also reported for California are Populus ×inopina (Populus nigra × Populus fremontii), Populus ×canadensis (Populus nigra × Populus deltoides).
