a third one from the under surface of the (primary) head itself. 
They are well developed.

A great number — by far the majority — of the heads are 
extraordinarily large and of different shapes. The normal heads 
being oval with a length of 6 m.m. and a width of 4 m.m. 
(fig. 13a), the abnormal are apparently orbicular but in fact 
reniform (} and c), although somewhat irregular of outline. Their 
length varies from 5 mm. to 1.5 c.m., the width from 6 m.m. 
to 1.5 cm. The abnormal heads are shorter stalked than the 
normal ones, moreover it deserves attention that the peduncles 
of the former (4 and c) bear a few scattered scales not united 
to an involucre as in normal heads (a). 
The most remarkable fact, however, is that the receptacle 
which is under normal circumstances somewhat arched in the 
abnormal heads can be scarcely recognised as such but is replaced
