Re: Thorns at anubiases


Hi Marek,

There are species in the genus Homalomena in the Neotropics, but whether 
they BELONG in the genus is far from conclusive. A recent molecular study 
seemed to show that the Neotropical species are embedded in Philodendron, 
but work we are doing here suggests that the situation is rather more 
complex and that there may well be several genera involved.
