There is a tendency even in genuine Carduaceze to irregularity 
of the flowers of the circumference, hence the question, which 
is the typical form of Compositz ? Is it that in which this ten- 
dency is carried into full effect, as in Ligulatz, or is it tha, 
which possesses the greatest regularity, and consequently that in 
which it is least worked out, as Carduacez ete., or is it that in 
this which general tendency is executed, as well as another less 
general—namely, the tendency te regularity as we approach the 
centre—Corymbifere. This question can only be decided by 
examination of the whole order. I am almost persuaded that 
there are three types of formation of different value, which 
will be found to pass into each other at various points to a - 
greater or less degree. "These types are pointed out by struc- 
ture, as well as by sensible properties, or the waut of these, 
. which last occurs in Carduaceze or Cynarocephale, while 
Ligulate are milky, and Corymbiferz very generally aromatic 
and glandular. 
In a species of Carduus from Candehar, the florets in a very 
“state consist of a calyx with a rudimentary toothed 
limb, a valvate corolla nearly partite toits base, and 5 smaller 
Similar bodies, the rudiment of the anthers. Traces of a female 
organ are evident, in the form of a small central projection, but 
no ovulum, see Pl. CCCCLXVI. Fig. h. The development 
appears to be equal except as to pollen, which is of late 
formation. 
The subsequent changes take place with too much rapi- 
dity to be observed in their several stages. 
The stigmata of Anthemidea 638,* or rather the stigma- 
tic surfaces of the branches of the style are peculiar, and rather 
incompatible with the idea that the stigma is the denuded 
apex of the midrib, for it is plain, that the stigmatic surfaces 
are confined to the margins of each branch, these becom- 
ing confluent and = distinctly papillose at the apex
