Artemesia tridentata Pursh. This is considered a sure remedy 

 for pneumonia, being taken internally, and also a poultice made of 

 it and applied to the chest. One of my men was taken violently 

 sick with mountain fever, his temperature going up to 104° and re- 

 maining there; when other remedies failed, I gave him a large quan- 

 tity of the cold infusion of the leaves, which cured him in a i^^^' days. 



Malacothrix Torreyi Gray. The flowers close at night. 



Crepis occidentalis Nutt. The flowers close at night. 



Lygodesmia spinosa Gray. This plant it seems to me has been 

 wrongly referred to this genus; it is a better Stephanorneria; in habit 

 it closely resembles the perennial species and also ChcEtadelphia, 

 which is hardly distinct. In some specimens recently sent me from 

 Idaho by Mrs. Brodhead I found the upper 4 of the pappus was 

 long plumose like Stephanomer'ia in man}- cases, while the rest oi 

 the pappus was strongly barbellate. The pappus is stout at base 

 and differs from Stephanorneria in being multisetose only. 

 \y Primula Brodhead.^ n. sp. 2 to 4 inches high; i to 4 flowered; 



scape 2 to 4 inches long; leaves i to 4 inches long, narrowly ellipti- 

 cal, rounded at apex, glabrous, rather thick, smooth, entire, narrowed 

 at base to a winged petiole an inch or less long; flowers purple, about 

 5 .lines wide, lobes orbicular or nearly so, notched, with a very short 

 claw 2 lines long, tube exceeding the calyx by 2 lines; funnel form 

 above the calyx; calyx lobes 1% lines long and subulate lanceolate, 

 barely acute, equaling the tube of the calyx; pod nearly spherical; 

 pedicels of lateral flowers about a line long, the terminal one 2 to 6 

 lines long; bracts oblong to ovate lanceolate, entire or toothed at 

 apex, I to 6 lines long; base of plant covered with the dead sheaths 

 of former leaves; roots like those of P. Parryi. Marshy places at 

 Ketchum, Idaho, May to early June, altitude 6,000 feet. The per- 

 fume at first is rather strong and sweet. Dedicated to Mrs. Brodhead, 

 the collector. 



Var. minor n. var. Leaves an inch long or less, elliptical oblance- 

 olate and acute, thin; lobes of the corolla as large as the type, but 

 obovate; lobes of the calyx longer than the tube; flowers i to 2 on 

 the scape; bracts long; plant 2 inches high. Bay horse, Idaho, July 

 I, at 8,000 feet altitude, in marshy places. This is between P. Par- 

 ryi and P. nivalis, Ledeb, but if the characters given in the Synop- 

 tical Flora are good this is a new species. I suppose this species is
