Leaves paired (), hairless, leaf-stalks green, 1⁄4–1⁄2 inch (6–13 ) long. Blades elliptical, 1 1⁄2–3 1⁄2 inches (4–9 ) long, and 1–1 3⁄4 inches (2.5–4.5 ) wide, short-pointed at broadest beyond middle, and tapering to long-pointed base, slightly thick and leathery and turned under at edges, above shiny dark green with inconspicuous veins, beneath dull light green with tiny -dots.

Flowers 1–2 on short stalks at leaf bases, white, less than 1 inch (2.5 ) across, composed of greenish conical base () less than 1⁄4 inch (6 ) long, 4–5 rounded green that remain at top of 4–5 elliptical white petals, many threadlike white and with inferior and slender

(berries) 1–2 on slender stalks at leaf bases or back of leaves, round or elliptical, 1–1 1⁄2 inches (2.5–4 ) long, dark reddish purple or sometimes yellow, with 4 rounded thick 1⁄4 inch (6 ) long at thick-walled, pinkish or whitish, juicy, slightly sour to sweet edible pulp, aromatic. Seeds are many, rounded or elliptical, 3⁄16 inch (5 ) long, hard, light brown or yellow.

Sapwood is yellowish white and heartwood pale reddish brown. A fine-textured, moderately heavy wood used only for fuelwood in Hawaii.

are eaten raw or made into jam or jelly with strawberry flavor. One variety of larger size with large yellow is called yellow strawberry guava.

Introduced into Hawaii in 1825 for the edible but now thoroughly naturalized and established. It forms thickets in moist lowland areas up to about 2500 ft (762 ) elevation, rarely to 4,000 ft (1,220 ). Classed as a weed in pastures, rangelands, and waste places. Grown also in southern California and Florida.

An evergreen tree retains a large portion of its green leaves all year.

stamen -- the pollen-producing reproductive organ of a flower; The stamen consists of an anther supported by a filament.

style -- This is a long and thread-like structure that connects the stigma with the ovary. A flower may have a single style, or several of them.

synonym -- In botany a synonym is a species name that at one time was thought to be the correct name for a plant but was later found to be incorrect and has been replaced by a new name.

cm -- A centimeter which is about 0.4 inches.

In an opposite leaf arrangement the leaves come in pairs with one leaf on each side of a stem.

mm -- millimeter. About 1/25th of an inch.

The hypanthium or floral cup is a cup-like structure formed by the fused bases of the stamens, petals, and sepals.

calyx -- the sepals of a flower, typically forming a whorl that encloses the petals and forms a protective layer around a flower in bud.

m -- A meter is about 10% larger than a yard.

The apex is the tip or the furthest point from the attachment.

Glands are plant structures that secrete liquids, salts or other substances. Glands often appear as hairs with a drop of liquid at the end.

fruit -- any seed-bearing structure in flowering plants. It is formed from the ovary after flowering.

lobe -- Rounded parts of a leaf (or other organ). Lobes bulge out about 1/4 of the leaf diameter.

An ovary is a part of the female reproductive organ of the flower. Above the ovary is the style and the stigma, which is where the pollen lands and germinates to grow down through the style to the ovary.

A pistil is the female structure of many flowers. It contains one or more carpels. Each carpel contins an ovary, style and stigma. The stigma receives the pollen which grows thru the style to reach the ovary.
