424 SUPPLEMENT. 



California, Sonoma Co., Brewer, and valley of the Joaquin, Greene. (Chili, Eritrichium 

 uliyinosum, Philippi, & E. muricatum, A. DC. "?) 



* * Larger-flowered annuals, erect or diffuse : rotate limb of the corolla 3 to 5 lines in diameter, 

 bright white, with the yellow fornicate appendages of the throat conspicuous : nutlets rugulose. 



K. Chorisiana, GRAY, 1. c. 267, is Eritrichium Chorisianum, DC., p. 191. 



KL. Scouleri, GRAY, 1. c., is Eritrichium Scouleri, A. DC. 



KL. Cooperi, GRAY, 1. c. More diffuse or depressed-spreading, hispid throughout with 

 spreading short bristles : pedicels very short or none : fruiting calyx less than 2 lines and 

 nutlets hardly a line long. Eritrichium Cooperi, Gray, Proc. Am. Acad. xix. 89. Wet 

 places in the Mohave Desert, Cooper, Parish. 



* * * Perennial by creeping and rooting stems, leafy, and with flowers of moderate size. 



KL. Hiollis, GRAY, 1. c. Copiously soft-villons, even to the calyx : stems rather stout, 

 spreading or ascending, at length a foot or more long : leaves liuear-lingulate, 2 inches or 

 more in length and 3 or 4 lines wide, obtuse : spikes at length elongated, bractless : limb of 

 the corolla 3 or 4 lines broad : nutlets trigonous-ovate, slightly obcompressed, hardly at all 

 cariuate on the back, coarsely rugose-areolate, attached by a quarter or a third of their 

 length to the oblong-pyramidal gynobase, the scar ovate-lanceolate. Eritrichium molle, 

 Gray, Proc. Am. Acad. xix. 89. Alkaline borders of ponds, Sierra Valley, E. California, 

 Lcmuion. Also apparently near Visalia, Conydon. 



3. EUKRYNITZKIA, GRAY, 1. c. Nutlets (never rugose, but sometimes papil- 

 lose) attached by the ventral angle or groove from the base up at least one third 

 or half way or for the whole length to an elevated gynobase, the back convex 

 and not carinate, the sides wingless, and mostly obtuse or rounded, but several 

 in the later subdivisions acute-angled : fruiting calyx erect or closed : corolla 

 .small and white, with tube not surpassing the calyx : annuals with the flowers 

 almost always sessile and scorpioid-spicate. 



* HOLOCALYX, i. e. the fructiferous calyx not circumscissile, but not uncommonly articulated 

 with the rhachis and falling away at maturity with the nutlets included. Gray, Proc. Am. 

 Aead. xx. 268. 



+ Sepals lanceolate or linear, traversed by a rigid and stout midrib : nutlets thick-walled, opaque 

 or dull: diffusely branched and rough-hispid. 



H- Nutlets either dissimilar or only one maturing, strictly enclosed in the rigid fructiferous calyx, 

 the midribs of which are much thickened and indurated. 



KL. Crassisepala, GRAY, Proc. Am. Acad. xx. 268, is Eritrichium crassisepalum, Torr. & 



Gray, p. 195. One of the nutlets larger and more persistent. 

 KL. Texana, GRAY, I.e., is E. Texanum, A. DC., p. 195. Matures a single nutlet, which 



never separates by a clean scar, but at length tears away. 



-t"t- -n- Nutlets all four maturing and alike, smooth, ovate-acuminate, hardly a line long, attached 

 to a narrow gynobase, the ventral groove abruptly dilated at the very base into the triangular 

 scar: fructiferous calyx (about 2 lines long) less closed and less rigid than in the preceding, and 

 midrib less prominent, hispid with pungent bristles: spikes often bracteate at base. 



KL. Patterson!, GRAY, 1. c. A span or so high, branched from the base and spreading : 

 leaves narrowly spatulate or linear, seldom an inch long : sepals linear-lanceolate : nutlets 

 attached up to the middle to the subulate-pyramidal gynobase, one of them disposed to be 

 more persistent than the rest. Base of the Rocky Mountains, probably near Denver, 

 Patterson, and on the plains westward, to S. E. Oregon, Howell. 



KL. Fendleri, GRAY, 1. c. Erect and paniculately branched, rigid, a foot or less high : leaves 

 linear, an inch or more long : fructiferous sepals narrowly linear : nutlets more tapering 

 upward, nfh'xod nearly their whole length to the narrow subulate gynobase. (Hr.s been 

 much confounded with K. hiocarpa.) Saskatchewan to Colorado and New Mexico or 

 Arizona, chiefly along the base of the Rocky Mountains, but northwestward to the borders 

 of Washington Terr. ; perhaps first coll. by Fendler.
