123. General Hodes of Branching of Members. — All the 

 members of the plant-body may branch. This branching 

 always follows one of two general methods. In the one 

 the apex of the growing member divides into two new 

 growing points, from which branches proceed: this is the 

 Dichotomous mode of branching (Fig. 38). In the other

the new growing points arise laterally while the original 

 apex still retains its place and often its growth: this is the 

 Monopodial mode of branching (Fig. 39). Both modes 

 are subject to many modifications, the most important of 

 which are briefly indicated in the following table; and 

 moreover a member may branch for a time dichotomously 

 and then monopodially, or the reverse.
