Raceme

[2] A plant that flowers on a showy raceme may have this reflected in its scientific name, e.g. the species Actaea racemosa.

[2] Examples occur on Malabar nut (Justicia adhatoda) and chaff flowers (genus Achyranthes).

Examples occur on rice (species Oryza sativa) and wheat (genus Triticum), both grasses.

[3] An ament or catkin is very similar to a spike or raceme "but with subtending bracts so conspicuous as to conceal the flowers until pollination, as in the pussy–willow, alder, [and] birch...".

[4] A spadix is a form of spike in which the florets are densely crowded along a fleshy axis and enclosed by one or more large, brightly–colored bracts called spathes.
