Mallows, Rock-roses, and Allies of Zihuatanejo

Hornbeam-leaved melochia (Melochia nodiflora) is a low, spreading perennial herb or subshrub in the mallow family (Malvaceae), native to the tropical Americas. Small, pale pink to lavender flowers appear in tight clusters (nodal heads) along the stems rather than at the tips, giving rise to the species name nodiflora (“node-flowered”). Each flower has five delicate petals and a prominent central column of stamens typical of mallows.

Description

• Melochia nodiflora is a flowering herb or small subshrub in the mallow family (Malvaceae). It has branching stems, simple leaves with toothed margins, and small flowers that grow in dense clusters, often around the leaf axils or at the ends of branches. The flowers are typically pinkish to purplish, with five petals, and develop into small capsules containing several seeds. Like other members of the genus, it is adapted to warm climates and may grow as a low, spreading plant or an upright herb.

Range

• Melochia nodiflora occurs in tropical and subtropical regions of the Americas. It is native to Zihuatanejo, Guerrero, and the surrounding area.

Habitat

• This species grows in warm, open environments, including grasslands, scrub, roadsides, field margins, and disturbed ground. It favours sunny locations and is often associated with seasonally dry tropical climates. It can grow in a range of soils and may become more noticeable in open areas during the rainy season.
