If I was going to guess at 13 I might guess Anthurium debilis. But that inflo is incorrect. It doesn;t look like they have been able to provide optimum conditions for this particular plant. Its obviously very old as evidenced by the long meristem with the adventitious roots, but carrying only one leaf, it looks like it is struggling

I love to visit conservatory's also. Always have plants and trees that I have never seen before. Thanks for the look-see

I've been to the Botanical Garden and CalAcademy, but didn't even know this was in the same area.
Looks like I've been missing out.

Definitely adding this to my "must visit" list!
