576 SCR0P11ULARIACE.E. Orthocarpiuf. 



* Root perennial ! : lips of the short and yellowish corolla somewhat equal, the upper 

 beincj hroadish and blunt (straight) and tlie lower rather obscurely saccate : Jila- 

 vieuts (/labrous. 



1. O. pilosus, Watson. A spun or two high, uuuiy-stenuiieil from the linn root, 

 citlier solL-villous or hirsute, very Jealy : Iwives rather rigid, at least wlien old ; the 

 lowest linear and entire; the others 3-5-parted into narrowly linear diverging lobes; 

 the lower tloral similar, the upper ones Avith more or less dilated and sparingly 

 colored (white or yellowish) tips : spike dense, rather short : calyx somewhat 

 etpially 4-elert into narrow linear lobes which nearly equal the corolla, or theso 

 united at base in pairs : lower lip of the corolla at lirst equalling, at length a little 

 shorter than the ujjper ; its lobes ovate, shorter than the slightly saccate portion 

 beneath. — 0. jKillescens, Gray in Am. Jour. Sci. xxxiv. 3liU, & Proc. Am. Acail. 

 vii. 384, except a.s to Nultail's i)lunt. 0. j)allescens (iho more rigid form) & 0. 

 pilosus (the softer villous form), Watson, iJot. King Exp. 231, 459. 



Higlier parts of the Siena Nevada, from Tulare Co. to Sierra Co., and on Mount Shasta, at 

 5,000 to 9,000 feet (Brewer, Torreij, Kcllotjff, Lcmmon, kc); and in the interior of Oregon and 

 Idaho. CoroUa d to 8 lines long ; the lips only 2 lines long ; lower with the slightly ventricose 

 portion rather longer than tlie lohes, obscurely callous below the base of these, within more or 

 less plaited-tri&iccate. Stigma large, strongly capitate. 



0. P.A.LLESCENS, Gray, 1. c, as to Nuttall's Euchroma pallcsccns only (and wliieh may best 

 retain the name, since one is provided for the species confounded with it), proves to be identical 

 with 0. Parriji, Gray in Amer. Nat. viii. *2U, from the Rocky Mountains in Western Wyoming. 

 It is distinguished by a minute and somewhat hoary pubescence (even the inflorescence destitute 

 of villous or hirsute hairs), less leafy stems, looser spike, and the pair of calyx-lobes broader and 

 united liigh up, lower lip of the corolla rather more ventricose, and the floral leaves or bracts 

 nearly if not absolutely without colored tips. 



* * Root annual, as in all the following species. 



+- Filaments glabrous : vpper lip of the corolla straight or nearly so, naked, narrow, 

 lanceolate-triangular or broadly subulate ; the lowei- moderately ventricose, and 

 ivithin somewhat jtlnittil-trisaccate for its whole length; its teeth or lobes erect and 

 coHSj)iruous, obtoiig-Hncar : cajtsule oblong or oval. 



2. O. attenuatUS, Gray. Slender, strict, a sjjun or two high, mostly simple, 

 above hirsute-pubescent : leaves linear-attenuate with a few .setaceous lobes, or the 

 lower entire : spike virgate, loosely-flowered below, in small specimens Avith few 

 and rather scattered flowers : bracts Avith tlieir slender divisions barely Avhite-tijjped : 

 corolla narroAv throughout, only half an inch long, white or Avhitish, Avith oiie or 

 two purple spots on the lower lip, the narrow teeth of Avhich nearly equal the 

 upper. — Pacif. K. Pep. iv. 121. 



Borders of San Francisco Hay, &c. Also Oregon (E. Hall) to Puget Sound, Lynll. Resembles 

 a slender form of 0. hispidus, but in character more like a dejiauperate 0. densiflorus, into which 

 it may pass. 



3. O. densiflorus, Benth. Erect or diffusely branched from the base, a span 

 to a foot high, above soft-pubescent : lea\'es linear or linear-lanceolate and gradually 

 attenuate, Avith a few slender lobes, or the lower entire: spike dense, many-flowered, 

 at length cylindrical, or the lower floAvers somewhat scattered : bracts 3-cleft, about 

 equalling the flowers ; the linear lobes Avith jiurplish and Avhito tips : corolla from 

 two thirds to near an inch long, purpU; and white (the lips or their tips usually 

 purple), the teeth of the moderately dilated lower lip shorter than the upper. — 

 Scroph. Ind. & in DC. Prodr. x. 53G. 



Low grounds along the coast, from San Luis Obisi)o to Sonoma Co. Tlie stem is commonly 

 erect, rather than "difliise" ; and the van hUifolius, Benth., with few or no lobes to the cauline 

 leaves, is the conunoner form. Seeds small, short-oval, the mature nucleus very loose in the 

 cellular coat. 



4. O. castilleioides, Benth. At length diffusely much branched, a span or
