Jejewoodia
Jejewoodia is a genus of epiphytic orchids native to Borneo, characterized by their simple or branching stems and ensiform leaves. The genus is distinguished by its small, widely opening flowers, typically white with potential yellow accents on the labellum, and a pandurate, spurred or saccate lip.

About Jejewoodia
Jejewoodia is a genus of flowering plants that belongs to the Orchidaceae family. These orchids are native to the island of Borneo, where they are found growing as epiphytes on other plants, primarily trees. The genus was established and published in 1995, with its name honoring the English botanist Jeffrey James Wood, who specializes in orchids.
Description
Plants within the Jejewoodia genus are characterized by their epiphytic growth habit. They possess stems that can grow up to approximately 20 centimeters (8 inches) in length, which may be simple or branching. The stems exhibit rooting at the base and are leafy. The leaves are arranged in two opposite rows (distichous) and are ensiform, meaning they are shaped like a sword blade and flattened. The inflorescence, or flower stalk, emerges laterally from the axils of the upper stem portions. Each stem typically bears a single flower, though sometimes up to four or five flowers can open sequentially on the same stem. The floral bracts are small, less than 1/8 the length of the flower stalk, and are brownish in color.
The flowers of Jejewoodia are generally small, measuring up to 1 centimeter in diameter, and they usually open widely. The sepals and petals are most commonly white, with occasional variations to yellow or greenish-yellow. The labellum, or lip, is also typically white, sometimes featuring a yellow central patch at the base of its mid-lobe. Both the sepals and petals are free from each other and spread outwards. The sepals are narrowly elliptic and acute, while the petals can be broadly elliptic and obtuse, or narrowly oblong and subacute. The labellum itself is tri-lobed and pandurate, resembling the shape of a fiddle. It may be spurred or slightly saccate, constricted near the middle. The hypochile, a basal part of the lip, is channelled and thickened at the margins, which are erect. The epichile, the upper part of the lip, is transversely elliptic and emarginate, with a broadly triangular tooth in the sinus, or it can be rounded and thick. When present, the spur is narrow and shallowly conical, with a smooth entrance. The column foot is absent in this genus. The anther is elongated at the apex and bears four pollinia, which are coherent masses of pollen grains. The pollinia are ovoid and unequal, with a transversely elliptic viscidium and a linear stipe. The rostellum, a beak-like structure, is finger-like in shape.

Jejewoodia orchids are epiphytic herbs with stems up to 20 cm long. They have ensiform leaves arranged in two opposite rows. Their flowers are small, up to 1 cm in diameter, and typically open widely, with white sepals and petals and a pandurate labellum.
Where are Jejewoodia orchids found?
This genus of orchids is native to the island of Borneo. They are typically found growing on trees as epiphytes.
What colors are the flowers of Jejewoodia species?
The sepals and petals of Jejewoodia flowers are usually white. Less commonly, they can be yellow or greenish-yellow. The labellum is also typically white, sometimes displaying a yellow central patch at the base of its mid-lobe.
How are the flowers structured on a Jejewoodia plant?
The inflorescence is borne from the upper portion of the stems and is one-flowered per stem, although sometimes four or five flowers may open successively. The floral bracts are small and brownish. The flowers themselves open widely and are up to 1 cm in diameter.
What does the labellum of a Jejewoodia flower look like?
The labellum, or lip, of Jejewoodia flowers is tri-lobed and shaped like a fiddle (pandurate). It may be spurred or slightly saccate, constricted in the middle, with specific structures on its hypochile and epichile.
