Masdevallia is a large genus of more than 500 small epiphytic or lithophytic orchids from high-altitude cloud forests in the Andes and Central America, grown for their colourful, triangular flowers. Keep them very cool, humid and consistently moist; they are easy to lose if they dry out or get hot.

About
Masdevallia, abbreviated Masd in horticultural trade, is a large genus of flowering plants of the Pleurothallidinae, a subtribe of the orchid family (Orchidaceae). There are over 500 species, grouped into several subgenera. The genus is named for Jose Masdevall (?-1801), a physician and botanist in the court of Charles III of Spain.
How to grow it
The species are sensitive to inappropriate cultural conditions and will show signs of stress by leaf spotting or dropping. They can generally be grown in pots with sphagnum or seedling grade wood chips although a few species produce descending inflorescences and are best accommodated in baskets. In both cases the rhizome should remain at the surface of the medium in order to prevent rot.
Most of these plants are from high altitude cloud forests and require very cool conditions and abundant moisture throughout the year. They cannot tolerate dryness, low humidity, or excessive temperatures and the plants are very easy to kill. They will simply drop all their leaves and suddenly collapse if allowed to dry completely or are exposed to high temperatures. Many members of this genus from very high altitude cloud forests defy cultivation.
Where it grows
These plants are found from Mexico to southern Brazil, but mostly in the higher regions (2,500-4,000 m ASL) of the Andes of Ecuador and Colombia, Peru and Bolivia. They may be epiphytes, terrestrials or growing as lithophytes on damp rocks.
