32 MONOCHASIA [CH. 



borne, each ending in a younger flower and with or 

 without other still younger axillary flowers, we should 

 have a type of infloi-escence where the oldest flower is 

 terminal, wli ether it stands at a higher level or not than 

 the successively younger ones. 



The Harebell affords a good example. The primary 

 axis ends in a flower, and bears bracts along its length ; 

 from the level of insertion of the bract next below another 

 pedicel arises and ends in a younger flower, and a still 

 younger one is borne by a branch from the level of a bract 

 on this, and so on. In this way the advanced inflorescence 

 may present a superficial resemblance to a raceme, as 

 already described on p. 13, but it is obvious that the 

 whole has been built up in a totally different manner, 

 because the bracts stand on the side of the apparent 

 main axis opposite the flowers ; we have here, in fact, 

 a pseudaxis (Monochasium) or Si/mpodium ot' exactly the 

 same character as in the case of the example given in 

 Fig. 2, or of the Lime or Vine branches referred to when 

 dealing with ordinary shoots in Vol. i. pp. 114, 115; and 

 its true nature is betrayed at once by the relative positions 

 of the pedicels and bracts. 



Such an inflorescence comes under the general desig- 

 nation of a Cyme. Other examples are furnished by 

 Buttercups, Columbines, &c. They may be termed 

 racemose, corymbose, &c., in purely descriptive accounts, 

 where the form only is considered and not the order of 

 development. 



Examples of corymboid and umbellate cymes are 

 afforded by the following : 



Lime Cotoneaster Hawthorn 



Apple Beam Sorb 



Rowan Service-tree Elder 



Wayfaring Tree Guelder Rose Blackberry.
