Keys as per BioNET-EAFRINET :

Psidium guineense may be confused with Psidium cattleianum (strawberry guava) and Psidium guajava (guava). These species can be distinguished by the following differences:

• P. guineense has hairy (pubescent) younger stems that are almost rounded in cross-section (sub-cylindrical) and relatively small yellow fruit (1-2.5 cm long). Its flowers are usually borne in threes (occasionally singly) in the leaf forks (axils) and its hairy (pubescent) dull green leaves have 6-10 pairs of side veins (lateral veins).
• P. cattleianum has hairless (glabrous) younger stems that are rounded in cross-section (cylindrical) and relatively small purplish-red or yellow fruit (2-4 cm long). Its flowers are borne singly in the leaf forks (axils) and its hairless (glabrous) glossy green leaves have 6 or 7 pairs of side veins (lateral veins).
• P. guajava has hairy (pubescent) younger stems that are four-angled in cross-section (quadrangular) and relatively large yellow fruit (2.5-10 cm long). Its flowers are usually borne singly (occasionally in threes) in the leaf forks (axils) and its somewhat hairy (pubescent) dull green leaves have 10-20 pairs of prominent side veins (lateral veins).
