I submitted proposals to add a couple of Macropiper to the database and I'm not certain but I think I may have misspelled the common name as Micropiper.
I don't have access to new plant entries that I've submitted so hopefully I'm wrong and my spelling was correct.
There are quite a few Macropiper listed at the CoL that don't appear in our database but I'll just let admin. handle entering them so as not to cause a lot of work correcting my errors.
