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

 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 tin- sides. 



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

 with bracts hardly surpassing the flowers). Sierra Valley, Lemmcn: a diffusely spreading form, 

 with copious bracteal leaves, like those below, accompanying and much exceeding the flowers. 



§ 3. Calyx only 5-cleft, at maturity separating about the middle of the short tube by 

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

 ivhile the rest fulls away: otherwise as in t/ie next section. — Piptocalyx, 

 Gray, 1. c. (Piptocalyx, Torr.) 



8. E. circumscissum, Gray, 1. c. Very 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, 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 style. — Lithospermum circum- 

 scissum, Hook. & Am. Bot. Beechey, 370. Piptocalyx circumscissus, Torr. Hot.

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 Wyoming. 



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

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

 tral face or angle, either from base to near the middle or for 'dun, si tin whole 

 length, to a high, pyramidal or subulate receptacle (gynobase), which when 

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

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



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

 plains east of the Rocky Mountains and to Texas. 



i Nutlets round,,! (or at least not marginedor acute-angled) at tht sides, attached to

9. E. oxycaryum, I liny. Hirsute and somewhat canescent, a span to a 

 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 ] u,-,| tips : only one nut lei maturing, that lanceolate-ovate (a line 



and a half long), much Longer than il ynobase, to which it is attached only hy

10. E. leiocarpum, Watson, 1. c. Rough-hispid and loosely branched: li
