118 ERYTHEA. 



Suksdorf, no. 399; Nevada, A. Gray (coll. of 1872), near Belleville, 

 W. H. SchocJdey, no. 340 (coll. of 1880), and at Candelaria, no. 

 382 (coll. of 1886). This species has hitherto been confused with 

 C. aretioides, Watson, but may be distinguished readily from it by 

 the very marked difference in the size of the flowers. 



Plagiobothrys hispidus, Gray, Proc. Am. Acad. xx. 286, & 

 Syn. Fl. ii. pt. 1, 432. Sonnea hispida, Greene, Pittonia, i. 22. 

 Specimens collected by William C. Ousick on dry steep sides of 

 Steiu's Mountains, southeastern Oregon, 28 June, 1898, no. 1970a, 

 but for the slightly larger and somewhat less papillose-granulate 

 nutlets, agree in all details with the type specimen of the above 

 species. The collection of Mr. Cusick extends the range of the 

 species considerably northward. 



Krynitzkia micrantha. Gray, Proc. Am. Acad. xx. 275, & 

 Syn. Fl. ii. pt. 1, 428. Eritrichium micranthum, Torr. Bot. Mex. 

 Bound. 141; Watson, Bot. King Exp. 244; Gray, Syn. Fl. ii. pt. 1, 

 193. Fruiting specimens corresponding in every detail with this 

 species were collected by Willia7n C. Cusick on the sands of 

 Alvord Desert, southeastern Oregon, 7 July, 1898, no. 2020a. 

 The occurrence of this species in Oregon extends its range consider- 

 ably north of any station hitherto recorded. 



Krynitzkia mollis. Gray, Proc. Am. Acad. xx. 264, & Syn. 

 Fl. ii. pt. 1, 424. Eritrichium molle, Gray, Proc. Am. Acad. xix. 

 89. Specimens belonging to this characteristic and readily recog- 

 nized species were collected by William C. Ousick in moist alkaline 

 situations, Harvey Valley, Oregon, 18 July, 1898, no. 2045. 



riertensia umbratilis. An erect herbaceous perennial, 3 to 

 4.5 dm. high: stems 1 to 5 from the base, smooth and glabrous: 

 basal leaves elliptic-oblong to oblong-ovate, the blade 6 to 12 cm, 

 long, 2.5 to 4 cm. broad, obtuse at the apex, entire, narrowed below 

 into a long winged petiole; the upper stem-leaves sessile, lanceolate, 

 oblong-lanceolate to ovate, 5 to 12 cm. long, 1.5 to 3 cm. broad, 

 acute, glabrous upon either surface or inconspicuously appressed- 

 tuberculate-hispid above, more or less punctuate, margins hispidu- 

 lous with appressed hairs: inflorescence terminating the stems, 

 rather few-flowered, paniculate, usually nodding even in the fruit- 

 ing stages; /)edicels usually longer than the calyx: calyx 5 to 8 mm. 

 long, deeply 5-lobed; lobes lanceolate, acute, margins more or less
