I. Woody plants whose leaves have little or no petiole, and which 

 have branches along the axis from near the root. 



Boxwood 

 Privet 

 Bay laurel 

 Portugal laurel* 



II. Woody plants whose leaves have a pretty long petiole, and 

 which have a pretty considerable extent of unbranched axis from the 

 root upwards. 



Cherry Sycamore Laburnum 



Apple Maple Birch 



Pear Horse chestnut Lilac 



Lime Service-tree 



I cannot say how this law applies to plants which have not a woody 

 structure. 



III. Plants whose leaves have several ribs, or main veins, proceed- 

 ing from the base of the leaf, and whose branches tend to whorl 

 round the axis. 



IV. Plants with separate leaves, or leaflets, coming off from nearly 

 one point, and with branches of a similar kind. 



Laburnum (leaflets in threes) Common barberry Ranunculus 



Broom (leaflets in threes) Alchemilla alpina Fuchsia 



Rhododendron ponticum Lupin Columbine 



Azalea (tendency to verticil- Wood Anemone 

 lation in the leaves) 



In speaking of whorled branches I mean that either the leaf-stalk 

 or the branches, properly so called, one or both, tend to whorl round 

 the axis. 



V. Plants of which the branches and the veins of the leaves go off 

 at the same angle. 



* The Portugal laurel has a short petiole, and also a short, unbranched axis, 

 f The beech and oak are acknowledged by all woodmen to be branched from the 

 root, or near the root, when growing freely.
