Dyakia

Dyakia is a genus of orchids in the family Orchidaceae. It is native to Southeast Asia, with species found in Thailand, Malaysia, Borneo, and the Philippines. The genus was established by Heinrich Gustav Reichenbach in 1883, and it is named after the Dyak people of Borneo, who are known for their knowledge of local flora.

Species within Dyakia are typically epiphytic, meaning they grow on other plants, usually trees, for support. They are characterized by their monopodial growth habit, with a single stem that elongates over time and produces leaves and flower spikes from its apex. The leaves are often strap-shaped and leathery. The flowers are usually small to medium-sized and can be fragrant. They are typically borne on erect or arching inflorescences.

The taxonomy of Dyakia has been subject to revision. Historically, some species now placed in Dyakia were classified under other genera, such as Sarcochilus. Current classification generally recognizes a small number of species within the genus. They are relatively rare in cultivation and are often sought after by orchid enthusiasts for their unique characteristics and native origins. Conservation status varies among species, with some facing threats due to habitat loss and overcollection.
