Dr. Hooker in his account of this species has noticed that the 

 smaller lobes of the leaves throw out radicular fibres at the 

 folded edge of the leaves, and he quotes the observation of 

 Wahlenberg : " in ejus pagina inferiore versus oram inferiorem 

 papilla protuberat, primùm viridis, dein fuscescens et radicans." 

 In the specimens before me I find this description to be very 



correct.
