7. B. Torreyi, Cray, 1. c. DitHiso or dpcumbent, rougli-liirsutc or even hispid, 

 the hairs even of tlie oalyx not yellowish : stems branching and uniformly leafy : 

 leaves oblong (half an inch or less in length) ; the uppermost forming similar 

 bracts to the lax leafy and interrupted spikes : corolla apparently as in the preced- 

 ing species: nutlets broadly ovate and only the apex contracted, the broad trans- 

 verse ridges separated by narrow sunken lines, very smooth, or obscurely tuberculate 

 along the sides. 



Siona Nevada : YoHoniito Valloy niul Mountnins, Torrry (a ratlior slondor and iipriglit form, 

 with bracts hardly aurpassing tlio llowora). Siona Valley, Lcmmnn : a diUnaoly spri'udiiig Ibrm, 

 with copious bracteal loaves, like those below, accompanying ami much exceeding the (lowers. 



§ 3. Calyx only ^-cleft, at maturity separating about the middle of the short tube by 

 a transvei-se division, the membranaceoxis base persisting under the fruit, 

 while the rest falls away : othertvise as in tJie next section. — Piptocalyx, 

 Gray, 1. c. {Piptocalyx, Torr.) ^ 



8. E. Circumscissum, Oray, 1. c. Very low and diffusely mucli-branched 

 annual, an inch to a span high, whitish-hispid throughout : narrow linear loaves 

 (half an inch or less long) anil minuto llowors crowded on the branches, forming 

 leafy spikes : corolla without crests in the throat, bearing the stamens on the mid- 

 dle of the tube : nutlets (less than a line long) oblong-ovate, very smooth, attached 

 by almost the whole length of the narrow-grooved inner angle to the narrow almost 

 subulate receptacle (gynobase) which bears the short stylo. — Lithospermum circum- 

 scissum. Hook. <k Arn. Bot. IV-echey, 370. Piptocalyx circumscissus, Torr. JJot. 

 Wilkes Exp. 414, t. 12 B; Watson, 1. c. 240. 



Southwestern borders of the State and along the cnstcrn side of the Sierra Nevada ; also through- 

 out the interior arid region to Utah, Washington Territory, and Wyoming. 



§ 4. Calyx {as in the genus generally) deeply 5-par(ed, persistent, or sometimes at 

 maturity falling off tvhole with the fruit enclosed: nutlets attached by the ven- 

 tral face or angle, either from base to near the middle or for almost the rvhole 

 length, to a high jiyramidal or subulate receptacle {gynobase), which when 

 slender is commonly called the base of the style : the scar either a narrow 

 groove or broader. — Krynitzkia, Gray, 1. c. 



There are several species besides the following in the interior region, some extending to the 

 plains oast of the Rocky Mountains and to Texas. 



* Nutlets rounded {or at least not margined or acute-angled) at the sides, attached to 

 a slender mostly subulate gynobase by a narrow {or in No. 1 2 domnwardly ividen- 

 ing) scar or groove, occupying nearly its whole length : calyx very hispid, much 

 disposed to fall off when ripe as a sort of bur : style short : corolla small or niinnte : 

 annuals, mostly low and slender : flowers in at length elongated bractless spikes. 

 {Krynitzkia, Fischer & Meyer.) 



-t- Nutlets very smooth and shining. 



9. E. oxycaryum, Gray. Hirsute and somewhat canescent, a span to a foot 

 high, slender : leaves narrowly linear : spikes rather densely flowered, at length 

 strict : corolla naked in the throat : bristles of fruiting calyx rigid, partly reflexed, 

 inclined to have hooked tips : only one nutlet maturing, that lanceolate-ovate (a line 

 and a half long), much longer than the gynobase, to which it is attached only by 

 the lower part of the slender ventral groove. — Proc. Am. Acad. 1. c. 



Open grounds from Tejon to Oregon, also Arizona. Corolla only about 2 lines wide. 



10. E. leiocarpum, Watson, 1. c. Hough-hispid and loosely branched : leaves 

 linear: s|)ikes often Incoming loosely-flowered below: corolla (2 or 3 lines wide) 

 ■with crests in tiio throat : (^alyx very bristly : nutlets all 4 maturing, ovate or 

 oblong-ovate (barely a lino long), attached by the greater part of the slender groove
