ErilricMim. BORRAGINACEiE. 527 



7. E. Torreyi, Gray, 1. c. Diffuse or decumbent, rough-hirsute or even liispid, 

 the hairs even of the calyx 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. 



Sierra Nevada : Yosemite Valley and Mountains, Torrcy (a rather slender and uprif,dit form, 

 with bracts hardly surpassing the flowers). Sierra Valley, Lcmmon : a diirusely spveaduig iorm, 

 with copious bracteal leaves, like those below, accompanying and much exceeduig tlic flowers. 



§ 3. Cali/x only b-deft, at maturity separating 'about the middle of the short tube by 

 a transverse division, the membranaceous base jiersisting under the fruit, 

 u'hile the rest falls away : othenoise as in the next section. — Piptocalyx, 

 Gray, 1. c. (Pij)tocalyx, Torr.) 



8. E. circumscissum, Gray, 1. c. A^ery low and diffusely much-branched 

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

 (half an inch or less long) and minute flowers crowded on the branches, fornnng 

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

 dle of the tube : nntlets (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 style. — Lithospermum circum- 

 scissum, Hook. & Arn. Bot. Beechey, 370. Piptocalyx circumscissus, Torr. Bot. 

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



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

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



S 4 Calyx (as in the genus generally) deeply ^-parted, persistent, or sometimes at 

 maturity fcdling of ivhole with the fruit enclosed: nutlets attached by the ven- 

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

 length, to a high pyramided or subidate receptacle {gynobase), which when 

 slender is commonly called the base of the style : the scar eitlier 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 east 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. 12 doivnwardly widen- 

 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 minute : 

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

 {Krynitzkia, Fischer & Meyer.) 



-i- Nutlets very smooth and shining. 

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

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

 strict : corolla nake.l in the throat : bristles of fruiting calyx rigid, partly reflexed, 

 incHned 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'^cjf the slender ventral groove, — Proc. Am. Acad. 1. c. 



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



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



linear • spikes often becoming loosely-flowered below : corolla (2 or 3 lines wide) 



with crests in the throat: calyx very bristly: nutlets all 4 maturing ovate or 



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