Does anyone (assuming this applies only US collectors) have plants that look more like Ursulaea tuitensis but were labeled Ursulaea macvaughii?  There seems to be a mystery afoot and I would love to see more pictures of these plants.
Thanks for any help...

What's the mystery, Andy?  I don't have a mislabeled plant, but the name has gone through some changes.  It was originally published as Ae. macvaughii, then changed to Ae. tuitensis before finally being assigned to new genus Ursulaea.

Sorry to be obnoxiously mysterious, but there are plants that I have seen lately that don't match either really.  They look 'closer' to U. tuitensis, but are most definitely not...

They are easily distinguished, especially when they flower so if you aren't sure what they are then they are probably hybrids.

Hey Andy - not sure if this is relevant but here in OZ over the past year i've found myself pointing at broms saying 'Nice young U. macvaughii' but they're labelled as U. tuitensis. When I say young I mean 20-30cm in size.
This has happened on more than one occasion for me and i've since wondered if perhaps there is a green/yellow form of U. tuitensis?
No photos sorry! but my own U. tuitensis are small, tight and very very red simular to your habitat photos posted on here and John Catlin's photo on the FCBS.

I realise too that the right way to confirm is for it to flower - perhaps i'll buy one to grow out and see.

Hi guys,  this is mine and it does have a yellow tinge to it, but not in the photos.

Andy,

I'm growing out some seed from the Brom Soc of Aust labelled as Ursulaea macvaughii, I got the seed in 2008 or 2009.

Walking past them one has taken on a real red tinge; I wonder if there might be some distant hybrids between tuitensis and macvaughii getting around as macvaughii.

Rick

Both grown in side by side, the green one probably got slightly more light.

Thanks for your input guys.  U. tuitensis varies greatly in color.  If grown under soft conditions they can be emerald green, grown harder and in more sun they can be yellow or red.  But their adult form in unmistakable.  The big fat rhizomes that kind of lean to one side

Here is a green one:

Here is my other main clump growing in pretty much full sun until 3-4pm in the summer.

Here it is now with its more typical red color.

And see how the base/rhizome looks to 'crawl' along the ground?

It is great to see you guys have U. macvaughii Down Under and are growing it from seed.  Hopefully they are the true species and didn't get open pollinated (I hate to even say/think that!).  That will be an interesting seedling to watch Rick.  In habitat I don't think their ranges come that close, but you never know.  The habitat around where U. macvaughii grows might support a random disjunct population of U. tuitensis...but I doubt it.
