Helicoid Scorpioid 



True Dichotomous branching is very rare, being seldom 

 met with in leafy shoots. It may be seen in the roots of 

 Lycopods, in the shoots of Selaginella, and in the fronds of 

 some ferns. Racemose branching is met with in the stem 

 of conifers, also in the compound leaves of umbellifers and in 

 the roots of dicotyledons. A false dichotomy is seen in the 

 inflorescence of chickweed and other plants of the order 

 Caryophyllacese, also in the stem of Mistletoe. The sympodial 

 cyme is to be met with in the annual shoots of many of our 

 forest trees, such as the Elm, Beech, and Hazel.
