Stanhopea ruckeri Lindley 1843

In his 1963 article, "The Mexican Stanhopeas," Calaway Dodson suggested that Stanhopea x ruckeri was a natural hybrid of Stanhopea oculata and Stanhopea wardii. He writes:
"A specimen at the British Museum, labeled Stanhopea ruckeri by Lindley, contains two inflorescences, one of S. oculata and the other of an intermediate between S. wardii and S. oculata. Since we are left with a large group of variable hybrids between S. oculata and S. wardii and have no name to apply to them, it might be a reasonable approach to apply the name "Stanhopea X ruckeri" to the whole group, keeping in mind that the name must cover a "multitude of sins" and does not apply to a particular kind of Stanhopea."
Curious writing.

Also published in Orchids Australia, Volume 12, No. 4, August 2000:
"The mystery surrounding Stanhopea ruckeri. Roger Kramer has written many articles for us over the years on the genus Stanhopea. This species is only relatively new in cultivation even though it was described in 1843. However, there seems to be some confusion as to what is and what is not Stanhopea ruckeri."

Tissue cultured material of Stanhopea (ruckeri x intermedia) is available from Cevie in Belgium.
