sorry Ursula, I had intended to include the source (senility is almost in full force today):
https://en.wikipedia.org/wiki/...
Scrolling through the page it lists Epidendroideae then Higher Epidendroideae; many in my little collection fall in the the Higher Epidendroideae group and others are in Epidendroideae; I have others in other SubFamilies too, but was only curious about the distinction. Certainly not a show stopper.
