Re: Thorns at anubiases

Dear Dmitry,

As I mentioned in my last email, we are really not all aware of what role 
such prickles might play in the aroids. As Tom has also mentioned they occur 
in Neotropical Homalomena too. The definition of a thorn is an indeterminate 
structure (such as a stem or root) capable of lateral growth through 
branching (and even of flowering and bearing leaves in some instances, that 
have a protective role. Thorns are most commonly found in Rosaceae (e.g., 
Crataegus), Fabaceae (notably Gleditschia) and Rhamnaceae (many genera).

Very best

Peter
