428 ADDITIONS AND CORRECTIONS TO VOL. I. 



rather short pedicels, the somewhat minutely tomentose sepals rather narrow, about 

 6 lines long or less : ovaries glabrous. 



In the Sierra Nevada, as stated, and the only species of the group that has been found there ; 

 flowering July and August. 



7. D. trolliifolium, Gray. This species is glabrous, or the inflorescence some- 

 what pubescent with white usually spreading hairs, the large bright blue or reddish 

 purple flowers comparatively few, upon long spreading pedicels : fruit 8 to 12 lines 

 long : seeds dark, firm, obpyramidal, with a lighter truncate depressed summit. 



Common on ridges throughout Humboldt County, where the stockmen call it "cow poison" 

 (Rattan), and ranging northward to the Columbia River (Hall, Howell), on low dry grounds. 

 Flowering from March to June. 



D. OCCIDENTALE (D. datum, var. (?) occidentale, Watson, Bot. King Exp. 11). This alpine or 

 subalpine species ranges from Union County, Oregon ( W. C. Cusick), to Colorado. It is readily 

 recognized by the stiff glandular spreading pubescence, which extends rarely to the ovaries and 

 fruit : flowers numerous, dull or dark blue, very variable in size, the raceme often compound : 

 seeds light colored and somewhat spongy. Flowering from July to September. 



D. SCOPULORUM, Gray, of the Rocky Mountains from British America to New Mexico, has not 

 been found west of the East Humboldt Mountains, Nevada, Watson. It has generally more nar- 

 rowly dissected leaves than the allied species, and the pubescence is a fine hoary tomentum. The 

 fruit is also pubescent, about half an inch long, on stout suberect pedicels. 



8. D. nudicaule, Torr. & Gray. Follicles narrowly oblong, 6 to 12 lines long, 

 somewhat narrowed at base. The color of the flowers varies to yellow and greenish 

 (Mrs. R. M. Austin). 



9. D. cardinale, Hook. Follicles shorter and broader, obtuse at base. Flowers 

 also occasionally yellow, Mrs. A. E. Bush.

1. A. Columbianum, Nutt. (Substitute for A. Fischeri.) More or less 

 pubescent above with short spreading yellowish viscid hairs : galea varying much in 

 breadth and in the length of the beak. Torr. & Gray, Flora, i. 34. 



In the Sierra Nevada, from Walker River to Washington Territory, and eastward to Wyoming 

 and Colorado. The Siberian A. Fischeri differs especially in its more cylindrical almost beakless 

 galea, and in the pubescence, minutely puberulent or sometimes wanting.

2. C. Bigelovii, "Watson. In Whitewater Canon, San Bernardino Mountains 

 (S. B. Parish], growing 5 feet high, among rocks ; flowering in January or later.

1. N. polysepalum, Engelm. Collected at Santa Cruz by Hartweg, found near 

 San Francisco, and common about Humboldt Bay ; Plumas County, Mrs. Austin. 



A " white water-lily," doubtless a Nymphcea, is reported as growing in the mountain lakes at the 

 head of Eel River. The genus is not otherwise known as occurring on the Pacific Coast. It is 

 distinguished from Nuptuir by its 4 oblong-lanceolate sepals, numerous large subpersistent petals 

 imbricately inserted all over the ovary in many rows, stamens upon the ovary, the outer with 

 dilated filaments, stigma concave and umbonate, fruit depressed-globose and ripening under water, 

 and the seeds within a sac-like aril. 



Insert in ordinal character of Sarraceniacecc : 



Ovules anatropous, very numerous, on large placentae projecting from the axis.

1. R. Coulteri, Harv. From San Diego to Santa Barbara County; branching 

 from a shrubby base and growing 4 to 8 feet high ; flowering from May to August.
