Great success. Big compliments.
I am not sure that this is Anguloa xruckeri in the sense of Oakeley and as it was described as a natural hybrid coming from Venezuela (Ang. hohenlohii x Ang. clowesii). The interior is much too dark.
My guess is that it should be called Anguloa hohenlohii.
But many sources have contributed to this confusion, among them the Swiss Orchid Foundation and Ecuagenera.
For a detailed analysis and to keep it apart from Ang. brevilabris we need a side view of the lip.
For all specifically interested people I add a link to Oakeley's Angulo@ page
A Key to the Anguloa Species and their Natural Hybrids.
