COMPLEX CYMES

Suppose the true Dichasium to have one of the two 

 lateral axes suppressed at each branching; we then have 

 a sympodium or false axis (Monochasium) developed.

Fig. 12. Cymose Inflorescences of the more complex orders. A, a 

 Dichasium, the order of development of the flowers denoted by the num- 

 bering. B, a Scorpioid cyme, and C, a Helicoid cyme, both in plan. D, a 

 Rhipidium or fan-shaped cyme, and E, the same in plan. F, a Drepanium 

 or sickle-shaped cyme, and G, the same in plan. H, a Bostryx or Helicoid 

 cyme passing into a Rhipidium or fan-shaped cyme, in plan. J, a Scor- 

 pioid cyme passing into a Drepanium, in plan. K, a double Scorpioid 

 cyme, in plan. L, a double Bostryx, in plan. 31, a displaced double 

 Scorpioid cyme, in plan. In all cases the numbering gives the sequence 

 of the flowers (Ei). 



If the suppression is always on the same side we have 

 the so-called Helicoid type of cyme (Fig. 12, C) as in 

 Boragineae, if on alternate sides the Scorpioid type
