THE AMERICAN BOTANIST 53 



known species. A full set of specimens may show that this 

 also is new. Additional plants are being grown from seeds. 



50. Bpilohiurn DriiinmondU Hatisskn. In wet grounds. 

 Not conspicuous. 



51. Psilostrophe sparsiflora (Gray) A. Nels. This 

 bright yellow composite w^as so much like a Crucifer in appear- 

 ance as to deceive everybody. Near Endische. 



51a. Ptcrispora andronieda Nutt. We found this very 

 abundant. One plant had twenty-one flower spikes. Thou- 

 sands of plants wherever the yellow pine grew. 



53. Car duns bipinnatiis (Estw.) Heller. A very com- 

 mon thistle with pink heads and white-surfaced leaves; very 

 attractive to humming birds. I do not recall a minute when I 

 could not find humming birds by glancing at the nearest patch 

 of thistles. 



54. Hahenaria sparsiflora Wats. War God. 



55. Pentsteuwn cyananthus Braudegci Porter? In the 

 absence of flowers, this is little more than a guess. 



56. Lupiuiis laxiflonis Dougl. The abundant and only 

 lupine in bloom. 



58. Oenothera coronopifolia T. and G. An abundant 

 and attractive Oenothera with cream colored flowers found in 

 many dryish places but not often in sand. The banks of many 

 dry washes were gay with these flowers. 



59. Oenothera pallida (Lind.) Brit. In sand, not com- 

 mon. 



60. Frasera speciosa Griseb. Columbo. Very Conspicu- 

 ous. Flowers greenish and 4-parted the perianth fringed. Up- 

 per slopes and summit of Navajo. 



61. Pentstemon Bridgcsii Gray. Seen frequently. 



62. Cornus stolonifera Michx. Betatakin Ruin and 

 elsewhere.
