This is another instance of the many analogies that might be 
pointed out between the Composite and Umbellifere ; its leaves, 
their dilated petioles clasping the stem ; the pubescence, and 
indeed the whole habit, has much the air of an umbelliferous 
plant ; and without the flowers the acutest botanist would not be 
censurable for mistaking it for one of that family. The struc- 
ture of its involucrum, the equality of its florets, and the rays of 
the pappus arranged in a double series, with dilated imbricate 
bases, abundantly distinguish it from Leuceria, to which it other- 
wise comes nearest in affinity.
