Notes: Diplocaulobium lageniforme is closely related to Diplocaulobium aratriferum, Diplocaulobium phalangium, and many other, similar species. The whole group is urgently in need of revision. D. lageniforme will probably turn out to be a common and widespread species.
Cultivation: Warm growing epiphyte.
