Hampe says of this, that the leaves are denticulate with in- 
curved spinules; but in Lindig's specimens the serration is very 
slight, and he states that the nerve is dilated above and occupying 
nearly the whole leaf; but on removing the lamell it is seen that 
the nerve is only one-third of the width of the leaf.
