Masdevallia amplexa is found in Peru. It occurs near Tingo Maria, central Peru at elevations around 1800 to 2000 meters above sea level.
Masdevallia amplexa also called as The Clasping Masevallia (amplexus - clasing refers to the petals), Alaticaulia amplexa, is a species of the genus Masdevallia. This species was described by Carlyle August Luer in 1997.
IDENTIFY MASDEVALLIA AMPLEXA ORCHID PLANT
Masdevallia amplexa is found in Peru. It occurs near Tingo Maria, central Peru at elevations around 1800 to 2000 meters above sea level.
It is a miniature sized, cool growing epiphyte with slender, erect, 2 cm long ramicauls enveloped basally by 2 to 3 tubular sheaths and carrying a single, apical, elliptic-oblong, subacute to obtuse, gradually narrows below into a cuneate, 9 cm long (including 1 cm long petiole) and 1.5 cm wide leaf.
The Clasping Masevallia blooms on a erect, slender, triquetrous, successively single flowered, congested, racemose inflorescence arising from the base of the ramicaul with a bract above the base and imbricating, acute floral bracts and holding the flowers well above the leaves. The flowers are 5 cm in diameter with yellow dorsal petal suffused with rose, the laterals deep red-purple, petals white with purple dots at the apex, lip rose, column white.
This species is distinguished from others in subsection Alaticaules by the concave synsepeal with the veins thickened within and relatively short recurving tails. Most distinguishing are the petals that clasp the column with dilated margins above the middle. The lip differs with the usual marginal folds becoming wing-like extensions of the margin above the middle.
MASDEVALLIA AMPLEXA ORCHID PLANT CARE AND CULTURE
Cultural information should only be used as a guide, and should be to be adapted to suit you. Your physical location; where you grow your plants, how much time you have to devote to their care, and many other factors, will need to be taken into account. Only then can you decide on the cultural methods that best suit you and your plants.
Light:
Masdevallia amplexa like good light, but not direct light. 17000 - 22000 lux is a good amount of light. About 70-90% shade is recommended in summer and 25% shade to full sun in winter. It will flower better if receive plenty of light and leaves are pale green rather than dark green when in heavy shade.
Temperature:
The Clasping Masevallia like cool growing conditions from 5°C to 25°C. Ideally in winter they like a minimum of 10°C in and a maximum of 13°C. In summer the optimum range is 13 to 20°C. The temperature should not exceed 25°C and temperatures consistently above 30°C will weaken the plants and they may drop their leaves.
Humidity:
This orchid prefer high humidity in summer near 75-80% and may need a humidifier over summer. Keep air circulation at all times to prevent water staying on leaves as this will encourage leaf spot.
Substrate, growing media and repotting:
Masdevallia amplexa can be grown in basket or net pots. They can also be grown in pots or mounted. They prefer a continuously damp medium. Some growers use chopped sphagnum moss mixed with polystyrene chips. Others use a pine bark, polystyrene and coarse perlite mix. A mix of 5 parts bark, 5 parts perlite and 1 part fibrous, not fine, peat moss is recommended. Their roots are small and many and will fill pots very quickly when growing well. Deeper pots are generally used and plants are potted out from being divided into 5cm tubes, 7-10cm pots or 12-15cm pots depending on size.
Repot or divide the plants during the autumn or spring every two years or when they are sufficiently large enough. It is best, as with most plants, to repot when the plants are about to root to minimize disturbance. Huge clumps must be divided as a considerable number of species tend to completely rot from the oldest parts of the clump. Do not bury the base of the plants. Double potting is beneficial to keep the plant roots cool.
Watering:
The Clasping Masevallia will not tolerate dry conditions and should be kept moist but not soggy. Their roots must be able to dry out slightly between waterings. In hot weather they need daily watering but in spring and autumn weekly watering should suffice. Water in the morning so leaves can be dry by midday. The plants should be provided with rain water or distilled water or a very pure water source. It is preferable to provide a humid environment than keeping roots too wet as they are prone to rotting.
Fertilizer:
Masdevallia amplexa are generally active throughout the year although growth may be slower in winter. Use a balanced fertiliser at 1/4 strength throughout the year; feed at every third or fourth watering. If in doubt do not feed. These plants do not like salt so roots will easily turn brown if over fed. If plants need a boost then a dilute foliar feed can be applied. Higher feeding schedules can be used if the grower masters their culture perfectly well. Do not use lime or dolomite lime.
