The Portugal Laurel has a short petiole, and also a short unhranched 

 axis. 



The Beech and Oak are acknowledged by all woodmen to be 

 branched from the root or near the root, when growing freely. 



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

 have a considerable extent of unbranched axis from the root up- 

 wards. 



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 proceeding 

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

 round the axis. 



Sycamore. Ivy. Nettle. 



Maple. Ground Ivy. Alchemilla. 



Currant. Pelargonium. Mallow. 



Gooseberry. Geranium. Potentilla. 



Guelder Rose. Hollyhock. Tussilago. 



Philadelphus. Rhubarb. Cineraria. 



Vine. Indian Cress. Violet. 



IV. Plants with separate leaves or leaflets springing from nearly one 



point, and with branches of a similar kind.

 Broom (leaflets in threes). Alchemilla alpina. Fuchsia. 



Rhododendron ponticum. Lupin. Columbine. 



Azalea (tendency to verticilla- Wood Anemone. 



tion in the leaves) . 



In speaking of whorled branches, I mean, that either the leafstalk, 

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

 round the axis. 



V. Plants of which the branches and the veins of the leaves spring at 



the same angle.
