Rhinostilis orchid: home care, species, transplant
The small genus rhinostylis (Rhynchostylis) is directly related to the orchid family. It combines a total of 6 species of plants. Under natural conditions, they can be met in Indonesia, Southeast Asia, as well as in the Philippines.
This plant has a monopodial nature of growth, which means that for all the time it grows only one vertically located stem. In the process of growth, the leaves located below die off and fall off, while from the remaining leaf sinuses strong air roots grow, on the surface of which there is a fairly thick layer of porous velamen. Regular, dark green, vaginal leaves on the shoot sit quite tightly. Thick, hard, almost succulent leaves have a belt-like shape, while their tip is not very flat, as if chopped off. From the leaf sinuses located below, peduncles grow, which carry multi-flowered inflorescences, which are clusters of a fairly large size. Small fragrant flowers have a rounded shape, and in diameter they are no more than 2 centimeters. 3 sepals (sepals) are very similar to the petals and have a wide oval shape. Sepals are located relative to each other at an angle equal to 120 degrees. 2 real petals (petals) lie opposite each other, while they are not as long and wide as sepals, although they have the same color. Having a contrasting lip color (3rd true petal), it has the same size as the petals, but it is bent perpendicular to the cup. The lip has a spade-like shape, while its edge is dissected or crusty. This genus was named rhinostilis because of its column (reproductive organ) of the coracoid form. So, from Greek rhynchos is translated as "beak".
Rhinostilis orchid care at home
This plant is not undemanding in care. In order for it to grow and develop normally, it is necessary to constantly maintain a certain temperature, humidity and lighting.
This orchid is photophilous and it is recommended to put it in a sunny place. However, from the scorching midday direct rays of the sun, it should be shaded to prevent burns on the surface of the leaves. If the lighting is too bright, then the leaves change their color to reddish, after the flower is removed in the shade, they again turn green. If there is little light, then the foliage turns dark green.
In order for flower stalks to form, you will need not only bright lighting. The duration of daylight also plays an equally important role. So, all year round it should be from 10 to 12 hours. In this regard, in autumn and winter, rhinostilis needs to be lit with phytolamps.
This plant needs to provide a moderately warm temperature regime. Moreover, it needs daily temperature differences. Day should be from 22 to 28 degrees, and at night - from 17 to 20 degrees. It should be noted that the difference in daily temperatures should have a difference of about 5 degrees.
This orchid substrate is not needed. It grows on a block with open roots. As a rule, a block is made of a large piece of pine bark, on which the roots and base of the stem are fixed. You can also use trellised baskets made of plastic or wood. Roots should pass freely through the holes in the walls.
How to water
Watering is done by immersing the root system in a basin filled with soft and necessarily tepid (30 to 40 degrees) water. After the leaf sinuses are thoroughly dried (if necessary, all liquid must be removed from them), the plant must be placed in its usual place. This should be done in order to prevent the formation of rot on the basis of leaflets.
High humidity is required. So, the humidity in the room should be at least 60-65 percent. To do this, it is necessary to provide systematic frequent spraying, and it is also just necessary to use a household steam generator, while the air stream must be directed to the roots.
Fertilize the plant from March to November. Feeding is carried out 1 time in 2 or 3 weeks, while using special fertilizers for orchids (take ½ part of the recommended dose on a pack). Dilute the fertilizer in water intended for moistening or watering the plant.
Being on the street
Being in the fresh air, such an orchid will be provided with an optimal temperature regime with the necessary temperature drops during the day, but at the same time it is necessary to choose a place with very high air humidity for it.
A plant can bloom in any of the months, while it does not need a dormant period.
When grown indoors, this flower cannot be propagated. By happy coincidence, a baby can form on the escape. It can be carefully separated from the mother plant only after the roots have completely formed.
Under industrial conditions, rhinostilis is grown meristemically (cloning) or from seed.
Pests and diseases
Resistant to pests. Often, rot may appear on the flower as a result of waterlogging, or the roots will dry out due to low humidity.
Also, the plant may not bloom. This is due to many reasons regarding violations of the rules of care. As a rule, this is observed due to low humidity and poor lighting.

The main types
In Russia, only 2 species are popular with orchid growers.
Giant Rhinostilis (Rhynchostylis gigantea)
This epiphyte is large enough. Fleshy leaflets have a length of 30 to 40 centimeters, and a width of 5 to 6 centimeters. The plant blooms in autumn and winter for 10-14 days. Dense inflorescences are attached to the peduncle, similar in shape to a cylinder and reaching no more than 40 centimeters in length. These inflorescences consist of 20-60 small (diameter about 2.5 centimeters) flowers, which have a small spur at the back. The sepals and petals at the base are narrowed, resulting in a rather large gap between them. The three-lobed lip has strongly raised lateral lobes.
There are 2 different forms of this type of orchid. One of them has snow-white flowers, and the other has white flowers, but there are purple-pink spots on the petals and sepals and the lip is painted in the same color shade as the spots.
Dull Rhinostilis (Rhynchostylis retusa)
Such an epiphyte is of medium size. Leaflets of this species are smaller than those described above, however, the flower stalk is somewhat longer (about 60 centimeters), and in inflorescences there are up to 100 small (diameter no more than 2 centimeters) flowers. 2 large sepals located below, have a wide oval almost round shape. At the same time, the third sepal, located on top, is not so wide and large. Narrow petals are superimposed on the sepals, while they close them, as a result of which a continuous cup is formed. Light pink flowers have small dots of dark pink color. The lip is also painted dark pink. It blooms in late winter and early spring.
