Amesiella monticola
Amesiella monticola is a miniature species of epiphytic orchid native to the Philippines. The specific epithet "monticola" refers to the montaneous habitat of the species. Monticola is a combination of "mons" or "montis", meaning mountain and "cola" or "colere" meaning "inhabitant" or "dweller". Description
These monopodial herbs form small, leathery leaves. The genus Amesiella forms white flowers with long spurs. The 1-6 very large flowers in relation to the vegetative parts of the plants are borne on short, axillary racemes. They have a characteristic long, twisted spur, indicating moth pollination. The flowers are purely white, devoid of any golden pigmentation of the labellum. This separates it from Amesiella philippinensis. Taxonomy
By some this species is treated as a mere variation of Amesiella philippinensis. Hence, it is synonymous with Amesiella philippinensis var. monticola. Conservation
This species is critically endangered and its population is decreasing. References
