The genus Dracula Luer, 1978, consists of 118 species and contains some of the more bizarre and well known orchids of the Pleurothallidinae sub-tribe of the orchid family (Orchidaceae).

Description
They were once included in the genus Masdevallia, but became in 1978 a separate genus. The strange name "Dracula" is derived from the Latin : little dragon, referring to the strange aspect of the two long spurs of the sepals.
These epiphytic and terrestrial species are distributed in Central America and the northwest Andes, almost half in Ecuador alone. They prefer shadow and an even, rather cold, temperature.
These caespitose orchids grow in tufts from a short rhizome, with a dense pack of stems. They lack pseudobulbs. On each stems grows one large, thin, plicate leaf with a sharply defined midrib. These glabrous, light to dark green leaves may be spongy, taking over the function of the missing pseudobulb. They are tipped with a mucro (a short tip).
The flower stalks grow upright. They may grow between the roots in some epiphytic species, hanging under the plant. The long-tailed terminal flowers are basically triangular. The flowers are borne singly or successively. But if there is more than one flower bud on the raceme, they open up with long intervals. These flowers have a weird aspect, due to the long tails on each sepal. The petals are small and somewhat thickened. The lip is small and inconspicuous. The fleshy basal part of the lip (hypochile) is cleft. The terminal part (epichile) is rounded and concave. The margins of the perianth are often fringed. There is a well-developed column with two pollinia.

Species
The species of Dracula have tentatively been divided in three subgenera, sections and subsections. The different series in the subsection Dracula are merely an attempt to classify these orchids.
- Subgenus Dracula : This subgenus contains all the species of the genus except two exceptional species (D. sodiroi and D. xenos)
- Section Andreettaea : Monotypic: Dracula andreettae
- Section Chestertonia : two species: Dracula chestertonii, D. cutis-bufonis
- Section Cochliopsida : Monotypic: Dracula cochliops
- Section Dodsonia : Four species: Dracula dodsonii, D. insolita, D. iricolor, D. portillae
- Section Dracula : largest section
- Subsection : e.g. Dracula bella, D. vespertilio
- Subsection Dracula :
- Series Dracula : e.g. Dracula chimaera, D. tubeana, D. vampira
- Series Grandiflorae-Parvilabiatae : e.g. Dracula gigas, D. platycrater
- Series Parviflorae : e.g. Dracula houtteana, D. lotax
- Subgenus Sodiroa : Monotypic: Dracula sodiroi
- Subgenus Xenosia : Monotypic : Dracula xenos
