im already doing my planning for this next summer. im looking to expand my Utric collection even more, they take up much less room than Neps. i have found most of the common species that have caught my eye and will be getting more but those are fairly easy to find. i have scanned growlists of some of the Utric nuts on here who have one and havent come up with much in the way of what i dont have, next step the CPUK forums. anyways ive come up with this partial list from the link Forbes provided me on epiphytic species. i figure some probably arent in cultivation. if you can think of other rare species in cultivation that i may have luck in searching out let me know. i would also be curious to see if someone had a more or less complete list of species that are in cultivation. anyways thanks for any help you can provide.
