Info on Urera baccifera ..

http://www.scielo.sa.cr/scielo...

Urera nitida .. the first photos show a stem with no visible thorns, the next ones do have thorns! It's from 'Universidade de São Paulo'.

I think the new stems may not have thorns, where older stems do from looking at the photos. It's interesting to note they haven't listed Urera baccifera in the side menu.
