those in the middle, some from below and some from above. The upper  
part is the extreme [top] of this ramification and the middle  
portion is more foreshortened than any other of those which are  
turned with their tips towards you. And of those parts of the middle  
of the height of the tree, the longest will be towards the top of  
the tree and will produce a ramification like the foliage of the  
common willow, which grows on the banks of rivers.  
Other ramifications are spherical, as those of such trees as put  
forth their shoots and leaves in the order of the sixth being placed  
above the first. Others are thin and light like the willow and  
others.

You will see in the lower branches of the elder, which puts forth  
leaves two and two placed crosswise [at right angles] one above  
another, that if the stem rises straight up towards the sky this  
order never fails; and its largest leaves are on the thickest part  
of the stem and the smallest on the slenderest part, that is towards  
the top. But, to return to the lower branches, I say that the leaves  
on these are placed on them crosswise like [those on] the upper  
branches; and as, by the law of all leaves, they are compelled to  
turn their upper surface towards the sky to catch the dew at night,  
it is necessary that those so placed should twist round and no  
longer form a cross.
