설명

Psidium guineense is a relatively slow-growing shrub 1-3 m tall and sometimes a tree to 7 m; with greyish bark, hairy young shoots and cylindrical or slightly flattened branchlets. The evergreen, greyish leaves, 3.5-14 cm long and 2.5-8 cm wide, are stiff, oblong, elliptic, ovate (egg-shaped with broad end at base) or obovate (egg-shaped leaf with the narrower end at the base), sometimes finely toothed; scantily hairy on the upperside but coated beneath with pale or rusty hairs and distinctly dotted with glands.

 

Flowers, borne singly or in clusters of 3 in the leaf axils, are white and have 150 to 200 prominent stamens. The fruit, round or pear-shaped, is between 1-2.5 cm wide, with yellow skin, thick, pale-yellowish flesh surrounding the white central pulp, and of acid, resinous, slightly strawberry-like flavour. It contains numerous small, hard seeds and is quite firm even when fully ripe.

 

Flowers are white and borne singly or in clusters of 3 on the leaf axils. Fruit is yellow and fairly round, 1-2.5 cm in diameter. Each fruit contains many small hard seeds.

Similar species

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

 

P. guineense(브라질구아바) 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 (스토로베리구아바)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).
