PLANTS FROM SOUTHEASTERN UTAH. 3OI 



leaves oblong, pinriately- parted; staminate flowers in 

 heads 4 mm. in diameter, 15-20 flowered, glandular spot 

 on the involucre inconspicuous, spike not dense. 



56. Annual, branched from the base with several 

 stems, which are simple up to the inflorescence, canescent 

 with appressed hairs; leaves smaller than the last, on 

 shorter petioles, similar in general outline and in the divi- 

 sions; staminate heads 3 mm. in diameter, in a dense spike 

 12-15 flowered; glandular ridge on the involucre prom- 

 inent. The fruit in both is so immature that differences 

 cannot be noted. 



Collected in Willow Creek Canon. 



57. Wyethia scabra Hook., Lond. Journ. of Bot., vi, 



Type locality: " Clayey argillaceous declivities of the 

 high hills of the upper Colorado River." 



Collected on a branch of McElmo Creek near the 

 bottom of the gulch; also, near the head of Willow Creek, 

 on the side of a low hill. Both sides of the leaf are alike, 

 and the tendencyto assume the upright meridional position 

 is marked. This is true also of other species of Wyethia. 



58. Helianthus petiolaris Nutt., var. canescens Gray, 

 PI. Wright., i, 108. 



Type locality of the variety: "Valley of the Rio 

 Grande, sixty or seventy miles below El Paso." 



This plant, judging from my specimens, connects H. 

 petiolaris, Nutt. with H. animus L. 



In the field it suggests a small form of H. annum with 

 canescent foliage. The shape of the leaves and manner of 

 growth and branching ally it with that species, while the 

 bracts of the involucre, the pappus scales and the size and 

 shape of the head, show its relation to H. petiolaris. 

 The plants grow to a height of from 4-5 dm. There is
