Discussion

Pyracantha fortuneana is native to central and western China. It is variable in the amount of toothing on the leaf blades and color of the hairs on new growth. Plants having grayish hairs on young twigs rather than the usual rusty or brownish hairs have been attributed to the taxon P. rogersiana, which has also been interpreted as a variety of P. crenulata. It is insufficiently distinct to separate from P. fortuneana among the specimens examined.
