270 WILSON’S OBSERVATIONS. 
the supposition of this being a state of T. Petasites, “in 
which the fertile or seed-bearing organs predominate,” I 
should still consider it, even in the absence of all proof of 
the fact, as more justly the type of the species than T. Petas- 
ites, « in which the radial florets are not found at all, and 
in which the only florets supposed to be fertile are ‘a few 
found occasionally towards the centre" of the disk. ' The 
abundance of rays on Tussilago Farfara has not, as it 
should seem, yet led to the suspicion of its being a variety. 
Suppose the existence of two states of Calendula officinalis, 
one, as is commonly seen in gardens, with the florets nearly 
all ligulate, and another with none but tubular florets ; and 
then in my opinion this case of Tussilago hybrida will be 
found an exact parallel to the first variety of Calendula, 
which is surely less distantly removed from its original state 
than the supposed second variety would be. 
It does indeed remain to be ascertained whether or not 
any of the florets in Tussilago Petasites, « produce perfect 
seeds; but I should consider the supposition of perfect 
central florets as wholly gratuitous; and even if proved to 
bé true, I cannot think it would furnish an argument in 
favour of the var. «. being the type of the species. 
Again, it is said that the flowers of Senatula tinctoria are 
*in effect dioecious, those in one plant having imperfect 
anthers, those, on another abortive stigmas.” Eng. Fl. iii. 
383. May not this be the case with Tussilago Petasites ?

I do indeed find the scales of the calyx not discoloured, as 
in S. sylvaticus, and the outer ones are, as stated in Eng. FL 
* very narrow and acute.” The herb is unpleasantly scented 
even when dry, but not at all like Fennel. Seeds with 
about twelve rows of close pressed hairs. Leaves rough 
on the upper surface. Receptacle honeycombed. Florets 
of the ray 3-toothed and strongly revolute. I cannot, as yet 
think it really distinct from S. sylvaticus.
