 ing stems leafy up to the thyrsoid inflorescence : leaves ovate and oval, entire or serrulate, 

 an inch or two long ; cauliue closely sessile by a broad base : sepals short, scarious-coria- 

 ceous, oblong-lanceolate, acute or short-acuminate : corolla an inch and a half long, rose- 

 purple. Mountains of Hood River, Oregon, near its confluence with the Columbia, Mrs. 

 Barrett. Here may belong an insufficient specimen from the northern side of the Columbia,

 steins '2 feet high and herbaceous (the base unknown): leaves elongated linear or linear- 

 lanceolate, 3 to 5 inches long, 2 to 4 lines wide, sparsely serrulate : sepals linear-lanceolate

 Parish. A foot or two high, woody below : corolla reddish, half-inch long. 



P. baccharifolius, GRAY. Not Mexican : for P. cor/amis, Schaffner in herb, (referred 

 in Hemsl. Biol. Centr -Am. Bot. ii. 443, to this species as var. Schaffneri), differs not only in 

 the smoothness and entire leaves, but in the shape of corolla and dehiscence of the anthers.

 rescence almost simply racemose : corolla more slender, light scarlet, destitute of beard ;

P- nudiflorus, GRAY. Ambiguous between the Specios'i and the Genuini: anther-cells 

 strictly divaricate, elongated oblong, dehiscent through the whole length, but not explanate :

 oval or oblong ; lower long-petioled ; upper smaller and half-clasping ; those of the elon- 

 gated and virgate racemiform thyrsus reduced to small or minute bracts : peduncles very 

 short, 3-5-flowered, but pedicels slender: sepals short, oval, obtuse: corolla (apparently 

 violet or blue) tubular, inch long (throat not over 3 lines wide), and lips only 2 lines long; 

 upper erect. 2-lobed; lower spreading and 3-lobed ; lobes roundish : sterile filament filiform,
