Arborescent, when tree-like in appearance, or ap- 

 proaching a tree in size. 



Diffuse, when loosely spreading in all directions, 



Declined, when turned or bending over to one side. 



Decitmbent, reclining on the ground, as if too weak 

 to stand. 



Assurgent, or ascending, when rising obliquely up- 

 wards. 



Procumbent, when lying flat on the ground from 

 the first. 



Creeping or repent, when prostrate stems on or just 

 beneath the ground strike root as they grow; as does 

 the White Clover. 



An annual herb flowers in the first year, and dies, 

 root and all, after ripening its seed: Mustard, Pep- 

 pergrass, Buckwheat etc., are examples. 



A biennial herb such as the turnip, carrot, beet 

 cabbage grows the first season without blossoming, 

 survives the winter, flowers after that, and dies, root 

 and all, when it has ripened its seed. 



A perenr'nl herb lives and blossoms year after 

 year, but dies down to the ground, or near it, annu- 

 ally rot, however, quite down to the root, for a 

 portion of the stem, with its buds, still survives, and 

 from these buds the shoots of the following year 

 arise. 



A Shrub is a perennial plant, with woody stems 

 which continue alive and grow year after year. 



A Tree differs from a shrub only in its greater size.
