Domain: Eukaryota Kingdom: Plantae Phylum: Spermatophyta Subphylum: Angiospermae Class: Dicotyledonae Order: Rosales Family: Rosaceae Genus: Pyracantha Species: angustifolia (Franch.) C.K
Pyracantha angustifolia is often misidentified as P. fortuneana or P. koidzumii; P. angustifolia is distinguished by the characteristic pubescence on the adaxial face of the leaves, the receptacle, and the calyx (Jocou and Gandullo 2019)
The origin of P. angustifolia in Australia is well described by Mulvaney (1991:33), who states that “between 1890–1920 plant collecting trips to China during this period resulted in an increased use of Chinese plants, including many newly described Chinese plants, such as P. angustifolia and Cotoneaster glaucophyllus being brought into cultivation for the first time beyond China’s borders.”

Vidal, Formosa firethorn [Pyracantha koidzumii (Hayata) Rehder], and Pyracantha rogersiana (A.B. Jacks) Coltm.-Rog (Plant List 2013). There are many cultivated hybrids and varieties of these species that vary mostly in plant size, fruit size, and fruit color (Egolf and Andrick 1995; Meyer et al 1994; see “Intraspecific Variation” and “Hybrids”)
