Arrangement:
Guava leaves grow in an opposite arrangement on the stems, meaning they occur in pairs, one on each side of the stem, at the same point.
Shape:
The leaves are typically elliptical to ovate or oblong-elliptical. This means they are generally oval-shaped, with a slightly wider middle and tapering towards the ends.
Size:
They typically measure between 5 to 15 centimeters in length and 3 to 7 centimeters in width.
Texture:
Leaves are leathery in texture.
The underside of leaves, particularly when they are young, may be pubescent (hairy).
The upper side is typically glabrous (smooth).
Veins:
There is a conspicuous midrib along the middle of the leaf.
Lateral veins arise from the midrib, and they are also quite conspicuous. There are usually 10-20 pairs of lateral veins.
Colour:
The leaves of guava are usually dull, dark green in color.
Petiole:
The leaves are shortly petioled (attached to the stem by leaf stalks).
Margins:
The margins of the leaf are entire, that is, smooth and not toothed.
Aroma:
Guava leaves, when crushed, give off a strong, pungent aroma, not unlike the fruit itself.
Benefits and Potential Uses:
Digestive Health: Guava leaves have been used to address digestive issues like diarrhea.
Blood Sugar Regulation: They are studied for their potential to help regulate blood sugar levels.
Immune Support: Their antioxidant content contributes to immune system support.
Oral Health: Guava leaf extracts are sometimes used in oral hygiene.
They are also used in some cultures for skin and hair health.
General Characteristics:
Shape:
Usually ovate to elliptic, i.e., oval in shape with a slightly pointed tip.
Some are more lanceolate (lance-shaped) in form.
Arrangement:
Alternately arranged on the branches.
Margins:
Margins of the leaf are serrate, i.e., small, tooth-like projections. These are often referred to as "double-toothed."
Veins:
The midrib is strong with lateral veins forking off from it.
Colour:
Mostly cherry leaves are deep glossy green.
In the fall, they can display brightly coloured shades of red, orange, and yellow.
Petiole:
Leaves are borne on the stem by a petiole (leaf stalk).
One feature in most cherry species is the presence of small glands located on the petiole, near the leaf base. These glands are called extrafloral nectaries and secrete a sugary substance attractive to beneficial insects.
Texture:
The leaves are either glabrous or moderately pubescent (hairy), depending on the species.
Benefits and Uses

Texture:
Mature leaves are leathery and have a smooth, glossy surface. Young leaves are much softer and more pliable.
Colour:
A notable feature is the color change during their life cycle. Young leaves often display reddish or purplish hues, transitioning to a deep, shiny green as they mature. The underside of the leaf is usually a lighter shade of green.
Venation:
The leaves have a prominent midrib, and the vein patterns are clearly visible, often with a lighter color than the rest of the leaf.
Margins:
The leaf margins are "entire" meaning they are smooth, but they can also be slightly undulate (wavy).
Detailed Characteristics:
Arrangement:
The leaves grow alternately on the branches.

Colour:
Mature leaves are a vibrant, deep green. Younger leaves may exhibit reddish or purplish hues before maturing.
Margins:
The leaf margins are serrated, meaning they have small, fine teeth along the edges.
