Rhynchostele rossii is widespread in Nicaragua, Honduras, Guatemala and Mexico. In Mexico, they appears in the states of Veracruz, Puebla, Mexico, Oaxaca and Chiapas. Usually, they grow in mixed rain forests, at heights of 2000-2400 m, but these plants have been found even at an altitude of 3000m.
It is a cold to cool growing, miniature epiphytic species, which reaching 10-25 cm in height, with ovoid to sub spherical, 3-6 cm long pseudobulbs partially enveloped basally by 2 conduplicate, acute sheaths and carrying a single, apical, elliptic to elliptic-lanceolate, acute, basally clasping, 5-20 cm long leaf.
Ross' Rhynchostele blooms in the winter till spring on a newly matured growth with a arcuate to pendant, 6 to 20 cm long, laxly up to 4 flowered inflorescence with lanceolate, acuminate bracts. The flower are 5.0-7.5 cm in diameter. They are pale yellow, white or pale pink with roundish brown or reddish spots on most surfaces of the outer whorl flakes and at the bases of the inner whale petals. The large, rounded lip is usually white or pale pink, about 2.5 cm in diameter and slightly wavy edges.

Light:
Rhynchostele rossii needs a light level of 25000-35000 lux. Clear, diffused light is recommended.
Temperature:
The average temperature of the summer day is 23-24 ° C, night 11-12 ° C, giving a daily difference of 12-13 ° C. The average temperature of the winter day is 21-23 ° C, the night 4-6 ° C, giving a large daily difference of 16-17 ° C.
Humidity:
In the summer and early autumn, Ross' Rhynchostele needs the humidity of 70-75%, in winter and spring it drops to 55-60%.
Substrate, growing media and repotting:
Rhynchostele rossii is best to plant on tree-fern rootstocks, with high humidity ensured and watering is carried out at least once a day in summer. When growing in pots, any loose, fibrous, fast-drying substrate is recommended. Repotting is best done at the beginning of spring, when new roots grow.
Watering:
Precipitation is moderate to heavy for 6 months from late spring to early autumn, but then the number drops sharply, going through 4-6 months of drought lasting until spring. The cultivated plants should be abundantly watered during active growth, but their roots must dry quickly after watering. In the autumn, when new growths reach maturity, the amount of water should be reduced.
Fertilizer:
It is recommended to apply a 1/4-1/2 dose of orchid fertilizer weekly. From spring to mid-summer, high-nitrogen fertilizer should be used, and then to a highly phosphorus fertilizer.
Rest period:
In winter, watering for Rhynchostele rossii should be limited, but not completely eliminated. It is usually sufficient to regularly sprinkle in the early morning between occasional, light waterings, which protects the plants from too much drying. If the pseudobulbs start to wrinkle, the amount of water needs to be increased slightly. Fertilization should be reduced or eliminated until spring, when the amount of water increases. In this period, the level of light should be at the maximum level, so as not to burn the leaves.
