TBH ABBANOMMJSNT OF FLOWERS, CONCLUDED 193 



221. The inflorescence of June-grass (Fig. 189) 

 is seen to be indeterminate, and yet it is not 

 clearly racemose, spicate, corymbose, or umbellate. 

 The fact is that the anthesis of the individual 

 parts of such a flower- cluster may be mixed, al- 

 though it is usually centripetal, or from below up- 

 ward (outside to inward). This type of branching 

 inflorescence is known as a panicle. 



221a. Racemes are sometimes borne close together, in such a way 

 as to suggest a panicle. The buckwheat (Fig. 190) is such a case. 



XXXVI. THE ARRANGEMENT OF THE 

 FLOWERS, CONCLUDED 



222. In the basswood (Fig. 191) the central or 

 terminal flower opens first. The branching is, 

 therefore, determinate. This type of flower -cluster 

 is called a cyme. 



222a. The pupil should determine the morphology or signifi- 

 cance of the singular leaf -like body a, Fig, 191, from which the 

 peduncle springs; and he should discover if this member is ohar- 

 acteristie of the lindens or basswoods. 



223. The apple (Fig. 192) also bears its flowers 

 in cymes, but the clusters are often only indefi- 

 nitely determinate. That is, there is not always a 

 definite progression in anthesis from inside out- 

 wards. Sometimes several of the flowers open
