Common name(s): [more details]

English: Brazilian guava, Guinea guava

French: goyavier du Brésil

Spanish: guayaba ágria

Habit:  shrub/tree

Description:  "Shrubs or small tree to 6 m tall, the branchlets subcylindrical; leaves to 12.5 cm long, the blades ovate to oblong-elliptic, rusty-pubescent beneath; flowers white, solitary or few together on slender peduncles, fragrant; fruit ovoid, brownish-green, turning to pale yellow when ripe, slightly acid."  (Welsh, 1998)"The Brazilian guava is a relatively slow-growing shrub 3 to 10 ft (1-3 m) tall; sometimes a tree to 23 ft (7 m); with grayish bark, hairy young shoots and cylindrical or slightly flattened branchlets. The evergreen, grayish leaves, 1 1/3 to 5 1/2 in (3.5-14 cm) long and 1 to 3 1/8 (2.5-8 cm wide), are stiff, oblong, elliptic, ovate or obovate, sometimes finely toothed; scantily hairy on the upper side 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 from 1/8 to 1 in (1-2.5 cm) wide, with yellow skin, thick, pale-yellowish flesh surrounding the white central pulp, and of acid, resinous, slightly strawberry-like flavor. It contains numerous small, hard seeds and is quite firm even when fully ripe" (Morton, 1987; p. 367).

"This plant is similar to P. guajava, but the twigs are not angled or slightly so, the leaf blades are elliptic, narrowly cuneate at the base, and sparingly hairy beneath, the flowers are up to 1.8 cm wide, and the fruit to 2 cm thick.  The fruit is smaller than the common guava, and is described as too bitter or resinous to be palatable"  (Welsh, 1998; pp. 200-201).

Habitat/ecology:  "The plant will not develop satisfactorily on light sandy soil" (Morton, 1987; p. 367).
