COMPOS TIT. 
In this Order the individual flowers which make~ 
up the “head” are usually called “florets” (a). They 
have no evident calyx, its place being taken, in some 
of the Genera, by a ‘“‘pappus” of scales (6) or hairs (c), 
more especially evident in fruit (e.¢, the familiar 
“thistledown”). Some of the Species can therefore 
only be well determined as the fruits ripen in the older 
(faded) flower-heads. 
“Bracts’’ in the Keys to this Order, means those 
which surround the flower-heads (@).
