Cyrtandra argentii is a plant in the family Gesneriaceae that was discovered in the Philippines in 1997.[2] This plant species is one of many named after tropical botanist George Argent, as he contributed heavily to many discoveries in and the understanding of Philippine flora.[2][3]
Type
PHILIPPINES • Mindoro Island, Oriental Province, Mt Halcon; 600 m; 13 Mar. 1997; Mendum, M., Argent, C.G.C., Pennington, R.T., Wilkie, P., Reynoso, E.J., Gaerlan, F. 29053 (holotype: E!; isotype: PNH). (1)[2]
Description
C. argentii is having pendulous compound cymose inflorescences of 10–15 flowers, subequal leaves, white woolly indumentum, glabrous corolla, and ovoid fruits.[4]
In detail, stems are slightly grooved 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.[2]
Habitat
C. argentii was discovered in and endemic to the Philippines.[2] Members of the genus Cyrtandra typically thrive in rainforest environments due to high humidity, constant moisture, and low light intensity.[2] It is found growing on slopes near streams, typically in forested environments, and distributed from north of Luzon to the island of Mindoro.[2]
Conservation
C. argentii is currently classified as a near threatened (NT) species by the International Union for the Conservation of Nature (IUCN) with the main threat to the population being deforestation coupled with a lack of formal protection.[2]
Other Philippine members of the Cyrtandra genus closely related to C. argentii include:[2]
- C. ferruginea
- C. villosissima
- C. hirtigera.
