B64 PRINCIPLES OF BOTANY, ETC. 
If the radius is full, then no disk can be seen, 
and such a flower gets much of the appearance of 
the flos semiflosculosus, from whieh however it may 
be distinguished at once, by there being not the least 
appearance of stamens. From the simple full flower 
the full compound flower differs in this point, that 
there is a style attached to each petal. ‘The radius 
of a simple radiate flower remains the same in a full 
radiate flower. If the radius is beset with prolific 
female flowers, then the full flower, consisting of 
mere linguiform flowers, is provided with prolific 
styles, and may without difficulty, if there be any 
natural plants in its neighbourhood, come to bear 
ripe seeds. If the radius, on the contrary, consists 
of barren female flowers, we commonly find them 
to be the same in the full flower. 
§ 341. 
Flos difformis, the deformed flower, is not a full, 
but a barren flower, which in its appearance is un- 
like the natural plant. It occurs most commonly in 
monopetalous flowers. Some of the labiate and rin- 
gent plants especially, belong to this kind, for in- 
stance, Ajuga, Mimulus and Antirrhinum. They 
crow sometimes longer than usual, assume the form 
of egg-shaped corols, which are narrower at the top, 
and divided into four lobes: several long spurs are 
protruded from their base, which in these flowers 
are distinguished by the particular name of Peloria. 
The Antirrhinum Linaria very often affords this 
variety.
