INTRODUCTORY LESSONS.

Suppose that one of the branches in 

 Fig. 54 had failed to grow. The first 

 flower would then appear to be axil- 

 lary. In the plant represented by 

 Fig. 57, two of each set of three 

 axillary buds usually remain dormant. 

 Their growth would complete a IVi- 

 chotomous Cyme. Fig. 54 represents a 

 Dichotomous Cyme. Imagine the plant 

 shown in Fig. 57 to continue branch- 

 ing, the stem to be shortened so as to 

 bring the flowers close together, and 

 the leaves to become obsolete. A 

 bunch of flowers, having the appear- 

 ance of a one-sided raceme, would be 

 formed. Let the flowers become ses- 

 sile, and we would have a false spike. 

 Such mimic racemes and spikes are 

 usually coiled as shown in Fig. 64. 



The common Anagallis, whose 

 pretty salmon-colored flowers appear i 

 the axils of the opposite leaves (Fig. 58) 

 is an illustration of simple Axillary Ii 

 florescence. Imagine the leaves reduced 

 to bracts, and the stem shortened. The 

 fruit, flowers, and buds would then form 

 a Bracteate Raceme. Let the bracts be- 

 come wanting, and we would have a naked 

 or Bractless Raceme^ similar to the one 

 shown in Fig. 59. This raceme wants 

 only a slight lengthening of the lower 

 pedicels to become a Corymb. Indeed, it 

 might be called a Corymbose Raceme. 

 Fig. 60 represents a naked raceme, in 

 "which only one or two flowers are in
