INFLORESCENCE.

CATKIN, or AMENTUM, is the same 

 as a spike, but in which the 

 flowers are imperfectly deve- 

 loped, as in the Hazel (Corylus), 

 Willow (Salix), White Poplar 

 (Populus Alba), &c. 



The RACEME has the inflorescence 

 placed along a common axis or 

 centre, the same as a spike, 

 but with the flowers placed 

 upon stalks instead of being 

 sessile, as in Water-cress (Nas- 

 turtium officinale) and Bed 

 Currant (Bibes rubrum).

The COEYMB is a form of inflores- 

 cence pretty much the same as 

 raceme, but the flowers of which 

 proceed upwards till they are 

 all on a level, as in Candy-tuft 

 (Iberis) .
