I am often curious about the origin of orchid names. Is there an
etymology reference available? Several examples:

Species

- Is D. nobile named after the Italian aeronautical engineer and Arctic
explorer Umberto Nobile?

Grex

- What about the more than 100 "Nobile's xxxxx", e.g. there are 52 grex
names of this form just within Blc., ranging from Blc. Nobile's Advance
through Blc. Nobile's Yolk?

Cultivar

- Do the numerous "Mendenhall" cultivars all originate from Carter &
Holmes Orchids, which is located on Mendenhall Road?
