86 THE AMERICAN BOTANIST 



per and pine forest, flowers are scarcely noticed, but when the 

 yellow pine forest is reached, the earth is carpeted with flow- 

 ers. 151ue lupines are everywhere, mingled with painted cup 

 and pentstemon. Goldenrods in dense tufts hold the open 

 places with occasional clumps of asters and pink thistles. Chief 

 of the floral list, however, was a handsome eriogonum whose 

 abundant and cheerful blossoms formed extensive patches of 

 bright yellow everywhere. Along the tiny stream that runs 

 down from War-god spring, grows an evening primrose with 

 bright yellow flowers three inches or more across — quite the 

 largest flower of the genus, so far as I can discover. On sunny 

 slopes grows another member of the Onagraceae with notched 

 leaves in rosettes after the manner of the dandelion, but 

 with flowers at least eight inches long and correspondinglv 

 broad. These open pure white but soon turn to pink and 

 wither by the end of the day. 



Another member of the evening primrose familv divided 

 its allegiance between mountain and plain. It was especially 

 partial to dry soils and was at its best on sunn)- slu[)es or flaunt- 

 ing its creamy-white blossoms from the precipitous banks of 

 the numerous arroyos. On the plains, a mallow with a most 

 unusuall color in which red, orange and vellow seemed strivine 

 for ascendancy, was very common and widely distributed. One 

 of the most interesting plants encountered was the pine sap 

 {Ptcrospora Aiidroincua ). It occured wherever the vellow 

 pine (lid and was so abundant as to attract attention nianv 

 times. It was in full flower, standing often more than two 

 feet high. One unusually thrifty specimen had twenty-one 

 spikes of flowers. 



'riie top of tile mountain presented nearly the same aspect 

 as liie slopes above 8,000 feet. There was a pretty little yellow 

 .sedum thickly scattered in open phices, a pink and wliite anten- 

 naria, handsomest of its race, phk)x, heuchera, pentstemons, 

 and painted cups, but no conspicuous masses of color.
