@Jim,
About the x in the name. You state the x is only used for natural hybrids. I always understood it only states that it is a hybrid. For example Dendrobium kingianum x D. tarberi. Now this one has been given a separate name (delicatum) so this becomes, when it is a natural hybrid Dendrobium x delicatum, or when you or I would have crossed it: Dendrobium x Delicatum with a capital to show its not a spontaneous trick of nature.
For the fun of it: Dendrobium delicatum (so without the x, no capital) would say it is a botanic species, and Dendrobium Delicatum (no x, with capital) would be a specific clone.
(I am no name specialist so i could be completely wrong, it's just how I understood it)
