Help needed to identify unlabelled Dendrobium

[paolo-56]

Thanks for helping! I went to the Malvern show for the second day and revisited the vendor with the intention of jogging his memory with your suggestions...but he had remembered that it is Dendrobium Stardust 'Chiyomi'. According to www dot hortusorchis dot org/en/hybrid-orchids/136-d/1897-dendrobium-stardust-chiyomi dot html, it's one-eighth nobile, which shows how much I know. (Sorry about the munged URL, the editor won't let me include a proper URL for some reason).
