The phyllotaxy in Guava is

Guava (Psidium guajava) exhibits opposite decussate phyllotaxy where leaves are paired at nodes, and successive pairs are oriented 90 degrees apart, creating four vertical rows of leaves. This specific pattern is called 'superposed' because each leaf sits directly above/below another in the vertical column. Alternate leaves (A) appear singly at nodes, decussate (C) describes the 90-degree rotation pattern itself, and ternate (D) refers to three-leaved arrangements.
