Vanilloideae is one of the subfamilies of orchids belonging to the large family Orchidaceae. Lindley (1836) and Garay (1986) treated it as a separate family, Vanillaceae. But their single, incumbent anther and poorly organised pollinia led to their recognition as at best a subgroup of monandrous orchids. From a molecular point of view, this clade is rather a sister to subfamily Epidendroideae and subfamily Orchidoideae in the Orchidaceae, and thus it is today also considered a subfamily. The subfamily Vanilloideae consists of 15 genera and about 180 species, belonging to the tribes Pogonieae

Oberonioides is a genus of orchids native to China and Thailand. Only two species are known: Oberonioides oberoniiflora (Seidenf.) Szlach. - Thailand Oberonioides pusillus (Rolfe) Marg. & Szlach. - Jiangxi, Fujian, Taiwan The genus name of Oberonioides is derived from Oberon, a king of the fairies in medieval and Renaissance literature.

Bulbophyllum jaapii is a species of plant in the family Orchidaceae. It is endemic to Cameroon. Its natural habitat is subtropical or tropical moist montane forests. It was described botanically in 2001. The distribution and range of B. jaapii is extremely limited; confined entirely to the summit forests and scrublands of a singular mountain in Cameroon (Mount Kupe, a dormant volcano on the Western High Plateau), at elevations of approximately 1,800 meters. It was first collected in November (during flowering), 1985 as a new discovery by D.W. Thomas and H.L. MacLeod, whom characterized them

Coeliopsidinae is an orchid subtribe in the tribe Cymbidieae. The three members of this subtribe have traditionally been lumped in with Stanhopeinae, but obvious morphological traits and new molecular analysis by Whitten et al. in 2000 confirmed the group reclassified by Szlachetko (1995). These genera have smooth, unribbed, ovoid pseudobulbs with 3-4 large and thin plicate leaves. The inflorescences are thick and bear globose flowers with thick, fleshy sepals and petals, presence of a column foot and mentum. Roots have prominent root hairs. Most distinct is the viscidia that are

Telipogon diabolicus is a species of orchid in the genus Telipogon. Only a single population of 30 plants are known to exist, on the border between the Putumayo and Nariño departments of southern Colombia.

The name diabolicus refers to the way its wine-red or maroon gynostemium looks like the head of the devil. Adult plants are 5.5–9 cm tall.
