430 SUPPLEMENT. 



= = Perennial, many-stemmed from a strong root, less hispid with incumbent bristles and 

 canescent with strigose-sericeous pubescence, at least the leaves. 



K. sericea, Gray, l. c, is E. glomeratum, var. humile, Gray, p. 196. Nutlets obloug-ovate, 

 somewhat rugose-tuberculate on the back. 



•H- -H- Lonir-flowered, the corolla-tube longer than the calyx and its own limb, with faucial crests 

 elongated and exserted: heterogoue-dimorphous, sericeous-canescent, perennial. Vide p. 197, 



K. fulvocanescens, Gray, 1. c. 280, is E.ftdvocanescens, Gray, p. 197. 



K. leticopheea, Gray, 1. c, is E. leucophwum, A. DC, p. 197, witli syn., &c. The remarkably 



long corollas are really yellow, and the polished ovate-triijuetrous nutlets are peculiar, 



rendering this an anomalous species. 



12. PLAG-I0B6THRYS, Fischer & Meyer, extended. (nXayioc, side- 

 ways, (i6dpo<i, pit or hollow ; so the name sliould have been written Plagio- 

 hothrus.) — Western American annuals, low, commonly diffuse, with small and 

 short-pedicellate or subsessile flowers ; the short corolla white : nutlets rugose or 

 roughened, rarely smooth, ventrally cariuate above the insertion, which is median 

 or supra-basal, or rarely supra-median, only one or two commonly maturing, and 

 then succumbent-horizontal upon the globular or depressed gynobase, tardily 

 detached, leaving a kind of caruncle at the insertion (either projecting and solid 

 or else annular and hollow), and corresponding depressed concavities on the gyno- 

 base. — Gray, Proc. Am. Acad. xx. 281. Plagiobothrys, Fischer & Meyer, Ind. 

 Sem. Hort. Petrop. ii. (1855) 46, & A. DC. Prodr. x. 134, a single species.

§ 1. Ambiguous species: gynobase ovate-pyramidal, commonly bearing all 

 four nutlets, and when they are detached deeply 4-sulcate, or as it Avere 4-lobed 

 by protuberant thickening between the imbedded bases of the nutlets, leaving 

 ovate-oblong or narrower depressions : nutlets tuberculate-roughened, incurved, 

 carinate on the back ; the caruncle longitudinal, narrow, and confluent with the 

 ventral keel above : coarse and comparatively robust plants, erect or merely 

 spreading, 8 or 10 inches high, unusually hispid for the genus; the inflorescence 

 evolute in fruit into mostly bractless racemiform si)ikes : calyx lax in fruit. 



P. Kingii, Gray. Hirsute and somewhat hispid: radical leaves spatulate ; upper cauline 

 oblong or lanceolate, half-inch long: corolla 3 or 4 lines in diameter (the largest of the 

 genus) : fructiferous calyx 2 or 3 lines long, its lobes linear-lanceolate: nutlets roughened 

 witli rather acute and scattered papilla. — Proc. Am. Acad. x.x. 281. ErUrichium Kinr/ii, 

 Watson, Bot. King Exp. 243, t. 23 ; also p. 192, in part. — Truckee Pass, Nevada, Watson, 

 in flower, and in same district by ^frs. Laiine-Curran, in fruit. (Tlie narrower-leaved and 

 sniallcr-tiowered specimens of Lemmon, without fruit, are wholly uncertain.) 



P. Jonesii. Hispid with long and widely spreading and pungent bristles, divergently 

 branching : leaves narrowly lanceolate, inch or two long (truly radical ones not seen) : limb 

 of corolla only a line or so in diameter : fructiferous calyx 3 or 4 lines long, divided to 

 the base into narrowly linear sepals : nutlets (a line and a half long) densely tubercuiate 

 with mostly obtuse papilla;. — S. E. California on the Colorado near The Needles, M. E. 

 Jones, 1884. 



§ 2. Genuine species : gynobase subglobose or merely convex, with orbicular 

 depressions left by the fall of the nutlets : these crustaceous or nearly so, very 

 seldom more than one or two ripening, therefore horizontally incumbent at 

 maturity, the caruncle short and broad, not stipitiform : slender or diffuse plants,
