A relook at this post was mandated today by a post on a WhatsApp Group, which may need checking our plants in cultivation. Two species which I have from California , initially mixed up but now clearly distinguished. The fruits in both turn from green to yellow, orange and finally nearly red as they fully matured. They are differentiated as:

Pyracantha coccinea: leaves narrowly elliptical, finely crenate-serrate along margin, tip acute, inflorescence pubescent.

P. koidzumii: leaves obovate-oblong, margin entire, apex obtuse, nearly rounded to emarginate, inflorescence glabrous.

This plant is clearly P. koidzumii.

I will upload real P. coccinea separately.
