Cyrtandra argentii

Cyrtandra argentii is a species of flowering plant in the family Gesneriaceae, endemic to the Philippines. Discovered in 1997, it is characterized by its pendulous inflorescences, white woolly indumentum, and ovoid fruits. This species thrives in rainforest environments with high humidity and constant moisture. Cyrtandra argentii is classified as Near Threatened by the International Union for Conservation of Nature (IUCN) due to habitat loss and deforestation.

The plant species is named after tropical botanist George Argent, who significantly contributed to the understanding of Philippine flora.

Description
Cyrtandra argentii has pendulous compound cymose inflorescences of 10–15 flowers, subequal leaves, white woolly indumentum, glabrous corolla, and ovoid fruits.

In detail, stems are slightly grooved and covered with white, woolly hairs. Leaves are subequal, 4 - 7 cm petioles with blades that are oblong to oblong-elliptical, asymmetrical, and typically measure in ranges between 13 - 30 cm x 7 - 15 cm. Compound cyme inflorescence type, pedunculate attachment, and the typical number of flowers inflorescence range from 10-15. Calyx is densely hirsute externally, glabrous internally, acuminate, and persistent. Corollas are white and glabrous both internally and externally.

Habitat
Cyrtandra argentii is endemic to the Philippines, specifically thriving in its tropical rainforest environments. These rainforests are characterized by high humidity, consistent moisture, and low light conditions, which are ideal for the growth of Cyrtandra species. The plant is typically found at elevations where the climate provides the necessary conditions for its survival. Habitat loss due to deforestation poses a significant threat to its natural environment.

Conservation
Cyrtandra argentii is classified as a Near-threatened species by the International Union for the Conservation of Nature (IUCN) criteria Cyrtandra argentii is classified as Near-threatened by the IUCN due to deforestation and insufficient formal protection.
