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 paginá inferiore versus oram inferiorem 
papilla protuberat, primüm viridis, dein fuscescens et radicans.” 
In the specimens before me I find this description to be very 
correct.
