The three nerves, visible in the leaf of these two species, are formed 
by a spiral thread which traverses the fibres of the root, runs up the 
petiole, and divides into three branches in the lamina. It is from the 
lateral branches of this spiral thread that the utricles, when present on 
the leaf, take their origin, and the cellular tissue at the origin of the 
utricle assumes the form of a beautiful dise, formed by long cylindric 
cells radiating round a central spot.
