Capsicum galapagoense

Capsicum galapagoense Hunz.

Capsicum galapagoense is a low, erect shrub native to the Galápagos Islands, belonging to the Solanaceae family. It is the only wild native Capsicum species in the region. The plant is characterized by dense pubescence, small flowers, and white corollas. It is part of the Annuum clade and is self-compatible, with experimental evidence of potential hybridization with other Capsicum species, including C. annuum, C. chinense, C. frutescens, and species from the Baccatum clade.

Description

Capsicum galapagoense is a low shrub, 0.5–1 m tall, with much branching from the base. Young stems are terete to slightly 2–3-angled and densely covered with white or yellowish-white pubescence. Leaves are membranous, ovate, and densely pubescent on both surfaces, with major and minor leaves differing in size. Inflorescences are axillary and 1–2-flowered, with short, angled pedicels. Flowers are 5-merous, with white corollas and small, red, pungent fruits. It is distinct from other Capsicum species in the Galápagos, such as C. frutescens and C. annuum var. annuum, by its dense pubescence and small flowers. It is self-compatible and can hybridize with other species in the Annuum and Baccatum clades, though hybridization with C. annuum or C. frutescens is considered unlikely in natural settings.
