426 SUPPLEMENT. 



Var. calycosa, GRAY, 1. c. A larger form, with flowers crowded in the short spikes : 

 fructiferous calvx elongated aud attenuate (2 or 3 lines long), becoming rigid and with 

 stouter midrib. Eritrickium leiocarpum, Watson, 1. c., as to "calyx-lobes linear, becoming 

 much elongated." E. Humboldt Mountains, Nevada, Watson, &c., arid Lake Co., Cali- 

 fornia, Rattan. 



K. Watsoni, GRAY, 1. c. Hispidulous and the calyx and the canescently pubescent calyx 

 sparsely hispid : fructiferous sepals barely 2 lines long, lanceolate, hardly at all attenuate : 

 nutlets narrow, somewhat triquetrous, oblong-lanceolate in outline, attached by their whole 

 length to the filiform-subulate gynobase. Eritrichium leiocarpum, in part, Watson, 1. c. 

 Wahsatch Mountains, Utah, Watson. 



JT- -i__ H_- Asperulous-fruited species, with nutlets disposed to be heteromorphous, i. e. one or two 

 of them larger than the others, all with ventral groove widening below and by this attached for 

 nearly their whole length to the subulate gynobase: diffuse, very small-flowered, with the spikes 

 bractless when well evolute: fructiferous calyx only a line or two long, armed with strong and 

 pungent divaricate bristles. 



K. angUStifolia, GRAY, is Eritrichium angnstifolium, Torr., p. 194. Low, forming broad 

 tufts, the herbage thickly soft-hispid and grayish : leaves narrowly linear: fruiting spikes 

 dense : sepals narrowly linear, beset with rigid bristles of nearly their own length : nutlets 

 small, somewhat trigonous, minutely scabrous by elevated points, with ventral groove del- 

 toid-ampliate either below the middle or next the base, sometimes all four alike, or one or 

 two longer and of ovate-lanceolate circumscription, while the others are triangular-ovate 

 and shorter, or these occasionally abortive. Proc. Am. Acad. xx. 272 (where the word 

 " semilineam " in the char, of section is a slip for " sesquilineam." - - Belongs to the interior 

 dry region of Arizona and S. E. California. 



K.. dumetorum, GREENE. Loosely branching, and among low bushes said to be almost 

 climbing, a foot or more high : only branches seen (those in fruit) ; with oblong or lanceolate 

 aud papillose-hispid leaves : fructiferous sepals lanceolate : nutlets narrow, acuminate, 

 minutely hirtellous-scabrous, three of them oblong-lanceolate in outline and almost terete, 

 with open ventral groove wider below the middle ; one much larger, fully a line long, 

 ovate-lanceolate, persistent on the subulate gynobase and fulcrate or half enclosed by a por- 

 tion of the then gibbous calyx, i. e. by two of the sepals united to the middle. (Possibly a 

 monstrosity.) Gray, 1. c. Tehachapi Pass, Kern Co., California, Mrs. Layne-Curran. 



.]_ 4 -j_ .{ Muriculate- or rough-papillose fruited, with bractless spikes, and calyx hispid with 

 spreading commonly pungent bristles: nutlets all four alike (occasionally only one or two ma- 

 turing), ovate-trigonous, more or less roughened by papilla? or tubercles on the convex back, at 

 least in age, and with sides or lateral angles rounded or obtuse (or more acute-angled in two 

 species), attached up to apex or nearly to the subulate gynobase by the ventral groove, with or 

 without arcola at its base: erect and mostly coarse herbs, the herbage more or less hispid. 



H- Calyx (and mostly herbage) very villous-hispid or barbate with long and rather soft bristles; 

 sepals narrowly linear and not tapering upward, with rather strong midrib, in fruit ;j to 5 lines 

 long, loose above, usually thrice the length of the ovate-acuminate or ovate-lanceolate very 

 rough-muricate and gray nutlets, the open groove of which is a little dilated at base. 



EL. barblgera, GUAY, 1. c., is Eritrichium barbigerum, p. 194. Common through the arid 

 region of S. K. California, Arizona, and Nevada, to adjacent borders of Oregon. 



H- -H- Calyx (not over 3 lines long) armed with more rigid and pungent bristles, these either 



whitish or rusty-yellowish, 

 = In fruit at least double the length of the more or less acuminate nutlets; the narrow linear or 



more attenuate sepals with rather strong midrib, open above, at least not connivent over the 



fruit. 



K. intermedia, GRAY. Nutlets thickly rough-mnricate, the papillos usually sharp-pointed ; 

 the groove wholly or partly open and with an open areola at base. Proc. Am. Acad. xx. 

 27:5. l-'.i-iii-irliiiuii inti niiiiJinin, Gray, Proc. Am. Acad. xvii. 225. Common through all the 

 southern part of California, and to the borders of Arizona. 



K.. ambigua, GRAY. Nutlets minutely papillose scabrous, moderately or hardly open at the 

 basal bifurcation of the mostly close groove. Proc. Am. Acad. xx. 273. Eritrichium 

 muriculatam, var. ambiguurn, p. 194, with syn. (The E. murlmlatum, of Torr. in Wilkes Exp. 

 represents the calyx rather too short.) Common in California, Nevada, and north ttf
