tinued by the first lateral branch we have definite or 
cymose branching. 
In the case of racemose branching the lateral branches 
are usually produced in a regular order, the youngest 
being nearest the apex. The branches are then said to 
be produced in ACROPETAL succession.

(In cymose branching if one daughter axis is given off at each node the 
term wniparous is used, if two, biparous, and if more than two, 
multiparous.) 
In the case of uniparous cymose branching we may 
have scorpioid, helicoid forms, and a form simulating 
a true dichotomy called a false dichotomy. 
In the scorpioid forms, the successive lateral branches 
are produced alternately on the left and nght. The 
apparently simple axis is a false axis made up of a 
number of lateral branches which have grown in the
