DWARF GOLDEN ASTER 



GOLDENROD 



Dwarf Golden Aster {Aplopappus) . This plant 

 exists in the Park in several varieties, but like the true 

 asters they resemble each other rather closely. They 

 occur only in rather dry, open places, growing in con- 

 siderable numbers on the hot springs formations at 

 Mammoth. The plant is six or eight inches high, fre- 

 quently with a shrubby base; small paddle-shaped 

 leaves, usually rather rough or hairy; the blossoms 

 resemble asters except that the petals are relatively 

 broader and bright yellow. The blossoming season 

 continues pretty well throughout the summer, begin- 

 ning in June and lasting until late in August. 



Goldenrod (Solidago). There are several kinds 

 of goldenrod in the Park, though not so many, perhaps, 

 as there are of the aster, for the goldenrod genus prop- 

 erly belongs to the plains and prairies rather than to 

 the mountains. In most of our species the stems arise, 

 straight and unbranching, in clumps from underground 

 rootstocks, bearing quantities of narrow, lance-shaped, 

 usually toothed leaves. The flowers are borne in dense, 

 feathery clusters at the top of a rather slender stem. 

 The blossoming season begins in July and continues at 

 least until the frost.
