as the numerous synonyms cited above show: it varies 
especially in the stem being winged and spinous-toothed, or 
wingless ; in the depth of the sinus at the base and apex of 
the leaf, and in its under-surface being glabrous or clothed 
with a white or brown cobwebby tomentum ; in the bracts of 
the involucre being all rounded at the point, or some or all 
terminated by a claw or foliaceous appendage, or the lower 
of them being much produced, lanceolate pungent and 
spreading or reflexed; and finally in the number and 
breadth of the ray-flowers. A series of twenty-five native 
specimens in the Herbarium displays all these variations, 
graduating into one another.
