Discussion

Pyracantha angustifolia is native to southwestern China. It is widely cultivated in North America but apparently naturalized only within California. The dense abaxial leaf indument can thin with age, but the distinctive dense hairs are found also on the sepals, even in fruit. The narrowly oblong to slightly oblanceolate, entire leaves are also diagnostic.
