62 STEM. 



Four ranked, when they spread in four directions, 

 crossing- each other alternately in pairs. 



Verticilled or whorled, when many surround the 

 stem at the joints. 



Diverging, when at right angles with the stem. 



Divaricated, when at an obtuse angle. 



Deflexed, inclining downwards in an arch. 



Reflexed, hanging perpendicularly. 



A Stem is termed 



Procumbent or trailing, when it is weak and lies 

 upon the ground, as the Wood-loosestrife, and 

 Bog-stitchwort. 



Creeping, when lying on the earth and striking 

 root at the joints, as the Creeping Crow-foot, 

 (Ranunculus repens) fig. 4, pi. 26. 



Ascending, lying partly on the ground and then 

 standing erect. 



Prostrate or depressed, lying flat and spreading 

 horizontally over the ground, as Swine's-cress, 

 (Coronopus.) 



Reclining, curved towards the ground, as the 

 Bramble, (Rubus.) 



Climbing, supporting itself by spiral tendrils, as 

 the Vine; or by fibres, as the Ivy; or entwining 

 round other plants either from left to right, as 

 Climbing Buckwheat, (Polygonum convol- 

 vulus) fig. 1. pi. 27 ; or from right to left, as 

 Great Bindweed, (Convolvulus sepium) fig. 2.
