BORRA.GINACE.E. 431 



little or not at all hispid, or papillose-hispidulous on some of the lower leaves : 

 small-flowered. 



* Typical, with an annular caruncle merely bordering a deep circular excavation, which is a kind 

 of false umbilicus: this suggested the name for the genus. 



P. rufescens, FISCHER & MEYER, 1. c. Often a foot high, with slender stems from the tuft 

 of spatulate-lauceolate radical leaves, only the young hirsute pubescence of the inflorescence 

 and calvx rufescent: spikes elongated and sparsely flowered at maturity, naked, or with a 

 leaf or two at base : fructiferous calyx lax, 3 lines long, of linear-lanceolate nearly distinct 

 sepals : nutlets (a Hue long) little incurved, broadly ovate and short-acuminate, rather ob- 

 compressed, lightly carinate on the back and margined, reticulate-rugose and muriculate, the 

 circular carunculate-bordered ventral pit about half a line in diameter. Gray, Proc. Am. 

 Acad. xx. 282. Mi/osotis alba, Colla (PI. Bertero, 88), fide A. DC. M.fu/va, Hook. & Am. 

 Bot. Beech. 38, not of 369. Eritrichium fulviuii, A. DC. Prodr. x. 132; Gray, Proc. Am. 

 Acad. xvii. 22G. W. Califoruia, from near the Oregon line, Hoirell, to Colusa and El 

 Dorado Co., Hfrs. Layne-Ciirran, and Sacramento Co., Xcrin, perhaps not very uncommon, 

 and perchance introduced (from Chili). 



* * Solid-carunculate, that is, the caruncle of the more incurved and ventrally concave nutlets 

 forming a broadish (commonly transverse) wen-shaped or short tongue-shaped caruncle: gyno- 

 base small and depressed. 



4 Mature nutlets abruptly contracted at base and apex, so as to become cruciatcly 4-lobed, 

 vitreous-crustaceous and more or less lucid, transversely lineate-rugose on the back with straight 

 and broadish wrinkles separated by very narrow impressed lines, and running from the low 

 median crest to the somewhat crested margins: calyx deeply 5-clel't, persistent, or at length im- 

 perfectly circumscissile : lobes broadly lanceolate, villous with rufescent or soon pale or fulvous 

 pubescence: plants small and erect, a span high or little more. 



P. tBnellllS, GRAY, 1. c., is Eritrichium tcnellum, p. 102, with syn. and habitat. Nutlets a 

 line long, muriculate-roughened. Herbage gives a violet stain to paper. Extends from 

 Brit. Columbia and W. Idaho to S. California. 



P. Shastensis, GREENE. Perhaps only a larger-flowered form of the foregoing, with calyx 

 (3 lines long) more closed over the fruit, and nutlets (a line and a half long) smooth or 

 barely the margins muriculate-roughened. Gray, 1. c. 284. 



4 H Nutlets broadly ovate and not at all cruciform, 



-H- Vitreous-crustaceons but rather dull, lineate-rugose in the manner of the preceding, but the 

 flatter back hardly at all carinate: calyx not circumscissile: plant diffusely procumbent, hispidu- 

 lous, with short oblong leaves which commonly extend through the irregular spikes. 



P. Torreyi, GRAY, 1. c., is Eritrichium Torreyi, p. 192. Herbage gives an abundant violet 

 stain to paper, 

 w- -H- Nutlets opaque, not vitreous nor much indurated, the back slightly carinate, rugose with 



sparse and somewhat reticulated lines, which are elevated above the general surface, this often 



minutely granulate. 

 = Calyx divided to near the base: spikes irregular or simple, commonly leafy below: limb of 



corolla only a line or two in diameter: plants diffusely branched from the base, a span to a foot 



high. 



P. Arizonicus, GREENE. Hirsute or even hispid with widely spreading hairs, not canes- 

 cent: leaves mostly oblong-lanceolate : fructiferous calyx not over 2 lines long, usually con- 

 nivent over the acutely rugose and sparingly roughened nutlets, at length circumscissile at 

 base. Gray, I.e. Eritrichium canescnts, var. Ari-nnionn, Gray, Proc. Am. Acad. xvii. 

 227. Common in Arizona, S. Utah, and adjacent parts of California, Palmer, Greene, Lem- 

 mon, Parish, Print/ fe. 



Var. Catalinensis lias fructiferous calyx open and the broader lobes somewhat 

 accrescent; also duller as well as rougher nutlets Santa Catalina Island, off I.os Angeles, 

 California, Lyon. 



P. canescens, BENTH., is Eritrichium cnnesrens, p. 192. Villous-pubescent and somewhat 

 cinereous or canescent, especially the calyx, which when young may bo fulvous or even 

 somewhat rufescent : this 2 or 3 lines long in fruit, loosely erect or sometimes more open
