Stelis poasensis - Long Column Foot Leach orchid flowers are about 1 cm in diameter, yellowish white in color.
Stelis poasensis also called as Long Column Foot Leach orchid, Pleurothallis poasensis, Anathallis dolichopus, Pleurothallis dolichopus, Pleurothallis lamprophylla, Pleurothallis peregrina, Specklinia dolichopus, Stelis lamprophylla, is a species of the genus Stelis. This species was described by Isler Fabián Chinchilla Alvarado and Adam Philip Karremans in 2019.
STELIS POASENSIS - LONG COLUMN FOOT LEACH ORCHID DESCRIPTION
Stelis poasensis is native to Costa Rica, El Salvador, Guatemala, Honduras, Mexico Southeast, Panamá. It is found growing on trees in wet montane forests at elevations around 1300 to 1600 meters above sea level.
It is a small sized, cool growing epiphyte which reaching up to 25 cm in height with glabrous, terete, up to 20 cm long, green colored ramicauls that are covered by several tubular brown sheaths. The single leaf is apical, coriaceous, elliptical, apically tridentate, obtuse to round, gradually narrows below into the conduplicate, petiolate base.
Long Column Foot Leach orchid blooms in the spring and the fallh from the terminal, racemose, 10-15 flowered inflorescens (up to 6 inflorescences on the same raceme). The flowers are yellowish white in color. Sepals are thin, outside is glabrous, inside is shortly pubescent; lateral sepals are connate to their bases. Petals are round, translucent with a carinate central nerve, wide and purple. Lip is arched, with two elevated purple carinae on the sides that are united approximately at the apex, with a less conspicuous carina at the center, green background with purple carinae and midlobe edpes. Column is, with a foot, yellow with purple stripes.
STELIS POASENSIS - LONG COLUMN FOOT LEACH ORCHID 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:
Stelis poasensis needs a light level of 15000-25000 lux. The light should be filtered or dispersed, and the plants should not be exposed to direct sunlight in the afternoon hours. Strong air movement should be ensured all the time.
Temperature:
It is a cool growing species. In summer the average day temperature is 20-23 ° C, the average night 13-16 ° C, which gives a daily difference of 8-10 ° C. In winter, the average day temperature is 18-21 ° C, night 10-13 ° C, with a daily amplitude of 7-10 ° C.
Humidity:
Long Column Foot Leach orchid needs the humidity of probably around 80% throughout the year. Too dry air has a negative effect on the development of the plant: its growth is inhibited, and the leaves begin to turn yellow and dry out. The higher temperature, the higher the humidity should be, and the higher the humidity, the more often and longer it is necessary to ventilate the room where the plants are contained, otherwise the probability of rotting and various kinds of fungal diseases. Good air movement is essential while the plants are in leaf and growing.
Substrate, growing media:
Stelis poasensis can be grown in small pots or baskets or mounted on pieces of tree ferns with peat moss pillows around the roots, with high humidity ensured and daily watering in the summer, during the dry and hot periods it may be necessary to water several times a day.
These plants are also grown in pots or baskets using a very loose, fast-drying substrate, such as fir bark or chopped tree fern fibers. Also, the materials that release the substrate but often retain a portion of the moisture, e.g. perlite, are often added to such a mixture. The addition of charcoal also improves the permeability of the substrate, and also protects against acidification.
Repotting:
Long Column Foot Leach orchid react badly to any manipulations, so they should be repotted or divided only when absolutely necessary. However, because these plants do not tolerate also the decaying soil around the roots, they should be repotted immediately when the substrate begins to decompose. Therefore, it is recommended to choose a substrate such as tree fern fibers, because these are slowly decomposed. If repotting is done at the time when new roots begin to appear, the plant will be accepted and rooted in the shortest possible time. If the plant was divided, it may take up to two years to recover.
Watering:
Stelis poasensis should be watered abundantly during the period of intensive growth from the summer to the beginning of winter, but excellent drainage should be ensured so that the ground around the roots is never desiccated or soggy.
Fertilizer:
During the active growth, Long Column Foot Leach orchid should be fertilized every week 1/4-1/2 of the recommended dose of fertilizer for orchids. From spring to mid-summer, you can use fertilizer enriched with nitrogen, then switching to phosphorus-enriched fertilizer in late summer and autumn.
Rest period:
Stelis poasensis need less water in the winter, especially if they grow under the conditions of a dark, short day that occurs in moderate latitudes. However, these plants should never be completely dried up. Fertilization should be reduced or eliminated until new growths appear and a more abundant spring watering begins.
