Rhynchostele rossii is an epiphytic orchid from the genus Rhynchostele.


Plants bloom from November to February in culture, with 3 - 5 flowers on up to 20 cm long inflorescences. Flowers are 5 - 7 cm in diameter.


There is one natural hybrid described - Rhynch. cordata x rossii = Rhynch. humeana, found in Mexico.

Rhynchostele rossii was used frequently in hybridization, already starting in the late 1800s. Better known progeny is Rhynch. BicRoss (x Rhynch. bictoniensis), which was later crossed back to Rhynch. bictoniensis to give Rhynch. Violetta von Holm.


Found in Mexico, Guatemala, Honduras and Nicaragua. Plants are growing in humid mountain forests at elevations of 2,000 to 2,400 m.


Rhynchostele rossii needs cool to intermediate conditions with moderate light, and high humidity during the growing season. Water the plant right before the potting mix starts to dry. Plants should be potted in a well drain medium such as medium fir bark.

Common name: Ross's Rhynchostele, named after John Ross, who collected the plant 1837 in Mexico.
