Spots large, irregular, commonly occupying the lobes and margin

Maculae magnae, irregulares, foliorum lobas marginemque oc- 

 cupantes, definitae, pallide brunneae, interdum supra margine an- 

 gusto inconspicuo, rufescento-brunneo; acervuli vulgo hypophylli, 

 rare epiphylli et tunc ad venulas, 120-160 /> lati, maculis brunniores;

Grindelia squarrosa (Pursh) Dunal 



Dry pastures on hillsides. Granville, Washington co. Septem- 

 ber. F. T. Pember. A showy introduced plant. 



Mr Pember remarks concerning it, " I can only suggest that 

 it may have been introduced in western grass seed. It is scat- 

 tered about over two acres, and in some places constitutes nearly all 

 the vegetation. There must be several thousand plants of it."

In a lawn. Rochester. July. M. S. Baxter. Introduced from

 nently established.
