3 Dracula velutina v. xanthina Dracula chestertonii The orchid genus Dracula, consists of 118 species. The strange name Dracula, literally means "little dragon", referring to the strange aspect of the two long spurs of the sepals. This genus has some of the more bizarre and well- known species of the subtribe Pleurothallidinae.

4 Dracula diabola 'Andina' Colombia

5 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 either horizontally from the base of the plant or descend, often for great distances. A few species grow upright flower stalks. The long-tailed terminal flowers are basically triangular. The flowers are borne singly or successively. These flowers have a weird aspect, due to the long tails on each sepal. The petals are small and somewhat thickened. The lip is often quite large for a Pleurothallid and may resemble a mushroom or fungus. 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.

12 The flower stalks grow either horizontally from the base of the plant or descend, often for great distances. A few species grow upright flower stalks. The long-tailed terminal flowers are basically triangular. The flowers are borne singly or successively. In general, though, 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 often quite large for a Pleurothallid and may resemble a mushroom or fungus. Dracula benedictii 'Ripley' Colombia

13 Dracula es un género con 118 especies que incluyen algunas de las más extrañas y a la vez mejor conocidas orquídeas de la subtribu Pleurothallidinae de la familia Orchidaceae. Dracula gorgona Colombia

14 Su extraño nombre "Dracula" deriva del latín : pequeño dragón, haciendo referencia al extraño aspecto que presenta con dos largas espuelas que salen de los sépalos. Estas especies epífitas y terrestres se distribuyen en Centroamérica y en el Noroeste de los Andes, casi la mitad de ellas en Colombia y Ecuador solamente. Tienen preferencia de sombra y temperaturas frescas. Estas orquídeas forman en ramilletes desde un corto rizoma, con un paquete denso de tallos. No tienen pseudobulbos. Con cada tallo desarrolla una hoja grande, delgada y picuda con un costilla media claramente definida. Estas hojas glabras de un color de verde oscuro a claro sustituyen las funciones del pseudobulbo ausente teniendo funciones de almacenamiento de nutrientes. Son puntiagudas con mucro (punta breve). Los tallos florales se desarrollan erectos. Se pueden encontrar entre las raíces de algunas especies epífitas, colgando debajo de la planta. Las flores terminales con largas espuelas tienen básicamente una forma triangular. Las flores se abren individualmente ó sucesivamente. Pero si hay más de un capullo floral en el racimo, abren entonces con largos intervalos. Estas flores tienen un aspecto extraño debido a los largos apéndices en cada sépalo. Los pétalos son pequeños y gruesos.

The leaves are upright and grass-like and the flowers come from the base of the leaves, but do not grow down through the medium like some of the the other species, but stick out from the base of the plant at approximately a ninety degree angle.
