Thank you for the kind offer, Ursula. We already have entries for all of those, except T. lepidum, which is now classified as a synonym of T. azureum.

It would be great, though, if you could add plant data to some of these entries. Just go to the entry, click on "Edit data details," and fill in the data fields and boxes with any information you may have. Plant comments are another highly appreciated addition to the database entries. If you have personal experience with these plants, or if you have useful information about them, please go to the entry, scroll down to "Post a comment," and tell us what you know or what you have heard from other sources.
