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, GUAY, 1. c., is E. glomeratum, var. humile, Gray, p. 196. Nutlets oblong-ovate, 

 somewhat rugo.se-tuberculate on the back. 



H. -M. Louie-flowered, the corolla-tube longer than the calyx and its own limb, with faucial crests 

 elongated and exserted: heterogone-dimorplious, sericeous-canescent, perennial. Vide p. 197. 



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



K. leucophaia, GH.VY, 1. c., is E. leucophceum, A. DC., p. 197, witli syn., &c. The remarkably 

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

 rendering this an anomalous species. 



12. PLAG-IOBOTHRYS, Fischer & Meyer, extended. (OXayto?, side- 

 ways, (369po<;, pit or hollow ; so the name should have been written Plagio- 

 bothrus.) -- 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 carinate 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. Plaffiobotkrys, Fischer & Meyer, Ind.

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

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

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

 ovate-ublong or narrower depressions: nutlets tubereulate-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 spikes : calyx lax in fruit. 



P. Kingii, OKAY. 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 calvx 2 or 3 lines long, its lobes linear-lanceolate : nutlets roughened 

 with rather acute and scattered papilla;. Proc. Am. Acad. xx. 281. Eritrirhinm Kingii, 

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

 in flower, and in same district by ^1/r.s. Layne-Curran, in fruit. (The narrower-leaved and 

 smaller-flowered specimens of Lemmon, without fruit, are whollv uncertain.) 



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

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

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

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

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

 .lone*, isst. 



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

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

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

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