Masdevallia сокращенная MASD в садоводческой торговле, является крупным родом цветущих растений Pleurothallidininae , , подтриба орхидей семейства ( Orchidaceae ). Есть более 500 видов , сгруппированных в несколько подродов . Род назван в честь Хосе Масдевалла (? -1801), врача и ботаника в суде Чарльза III в Испании .
Диапазон и морфология
[ редактировать ]Эти растения встречаются от Мексики до южной Бразилии , но в основном в более высоких регионах (2500-4000 ASL ) Анд Эквадора Колумбии и м , Перу и Боливии . [ 1 ] Они могут быть эпифитами , наземными или растущими в качестве литофитов на влажных скалах.
Растения характеризуются сокращением до удлинения и ползучих корневища , которое порождает стебли, в которых отсутствуют псевдобульбы. Стебель имеет единственный, мясистый, прямой, яйцевидный, яйцевидный или ланцетный лист . Цветы являются треугольными и встречаются по отдельности или в ракемных соцветиях. Они характеризуются эффектной чашечкой и уменьшенной венчик. Чашелистики . слиты на основе и часто хвостают Лепестки в форме языка окружают получетерную колонну, а губа гибко обобщена до свободной ноги колонки.
Cultivation
[edit]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.[2] 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. Most of the species from this genus are considered less difficult in cultivation than plants from the genus Dracula, and some of them are very easy to cultivate and have a 'weedy' habit such as Veitch's masdevallia, but the majority of these species are usually very difficult to maintain in cultivation unless the plants can be kept cool and moist all the time.
Low humidity conditions or watering the plants with a water source which contains high levels of dissolved salts will result in the leaves yellowing and rapidly dying from the tips back to the rhizome. The plants should be provided with rain water or distilled water or a very pure water source. The medium should always remain moist as the plants do not have any significant storage structures like most orchids.
