C. Coronopus grows in clayey soil from Kansas to Utah, Cali- 
fornia and Mexico. It is very variable and the more hairy forms 
grade into the less hirsute ones of the preceding. In the typical 
form the pubescence is sparse or nearly none, and the lobes of the 
leaves are short.

The most striking of the different forms of this species is a 
very low (1 dm. high or less) and bushy one, more stellate-pubes- 
cent and with much smaller leaves which are pinnatifid with very 
narrow lobes. It is represented by the following:
