Discussion
Pyracantha crenulata is native to southwestern China, India, Kashmir, and Nepal. A dwarf variant has been called var. kansuensis and is reported as native to China (A. J. Rehder 1949; Gu C. Z. and S. A. Spongberg 2003b); it is distinguished by its short stature (rarely exceeding 2 m), abundantly thorny branches, small leaf blades (1–2.5 × 0.4–0.8 cm), and small (3–5 mm diam.) red pomes. Its presence among the naturalized records of P. crenulata in California is suggested, but its morphology is not clearly distinctive. G. L. Nesom (2010) suggested P. fortuneana was not distinct from P. crenulata.
