§ 3. Krtnitzkia, Gray. Nutlets ventrally attached from next the base to 

 the middle or to the apex to the pyramidal or columnar or subulate gynobase ; 

 the scar mostly sulcate or slightly excavated: seed from amphitropous to nearly 

 anatropous, commonly pendulous : corolla (except in the last species) white • 

 calyx 5-parted, closed in hmt. — Kryniizkia, Fisch. & Meyer, Ind. Sem. Petrop.

E. Circumsclssum, Gray. Depressed-spreading, very much branched from the annual 

 root, an inch to a span high, whitish-hispid throughout: narrow linear leaves (a quarter to 

 half mch long) and very small flowers crowded, especially on the upper part of the 

 branches : nutlets oblong-ovate, smooth or minutely puncticulate-scabrous, attached by a 

 narrow groove (with transverse basal bifurcation) for nearly the whole length to the pyra- 

 midal-subulate gynobase. — Proc. Am. Acad. x. 58, & Bot. Calif, i. 527. Lithospermuvi cir- 

 cumsassuvi, Hook. & Am. Bot. Beech. 370. Piptocalyx circumscissus, Torr. in Wilkes Exp. 

 xvu. 414. t. 12. — Desert plains, E. California to Utah, Wyoming, and Washington Terr. 

 ''~uT~ ^^'7^ neither circumscissile nor disarticulating from the axis in age; the lobes linenr- 

 oblong, obtuse, nearly nerveless ; the bristles short and even, not setose or pungent : corolla with 

 minute if any appendages at the throat: nutlets attached for the whole length to a slender 

 columnar gynobase by a groove which does not bifurcate nor sensibly enlarge at base : flowers all 

 leafy-bracteate, short-pedicelled : style at length tWckened ! 



E. micranthum, Torr. Hirsute-canescent, slender, 2 to 5 inches high, at length dif- 

 fusely much branched : leaves linear, only 2 to 4 lines long: flowers in the forks, and much 

 crowded in short leafy spikes, about equalling the upper bracts : corolla barely a line high, 

 and its lobes one to two-thirds of a line long, obscurely appendaged at the throat : nutlets 

 oblong-ovate, acute or acuminate, smooth and shining or dull and puncticulate-scabrous (half 

 to two-thirds of a line long) : style becoming thicker than the gynobase, or even pyramidal. 

 -^Bot. Mex. Bound. 141; Watson, Bot. King, 244. — Dry plains, western border of Texas 

 through Utah and Arizona to E. California, where larger flowered specimens connect with 

 _ Var. lepidmn. Less slender and more hirsute : corolla larger, its expanded limb 2 or 3 

 lines in diameter ; the appendages or folds in the throat very manifest : nutlets nearly a 

 line long, puncticulate-scabrous. — California, in San Diego Co., D. Cleveland. 

 ••" 1- ,•»- Calyx not circumscissile, 5-parted, conspicuously and often pungentlv hispid with Inrge 



stiff bristles, and the lobes usually with a stout midnerve; the whole calyx (or short pedicel) in. 



several species inclined to disarticulate at maturity and to form a sort of bur, loosely enclosing 



the nutlets : inflorescence scorpioid-spicate, without or partly with bracts. 

 •H- Gynobase slender and naiTOw : nutlets with narrow grooved scar, or continued into a groove 



above the attachment and so running the whole length of the ventral face : spikes when developed 



mainly bractless : leaves in all linear. 



= Lobes of the fructiferous calyx very narrow; the strong bristles below reflexed and partly unci- 

 nate: appendages in the throat of the small corolla obsolete or wanting: only cue nutlet 

 usually maturing. 



E. oxycaryum, Gray. Somewhat canescently strigulose-pubescent or above hirsute, 

 slender, 6 to 20 inches high : leaves narrow : spikes dense in age, but slender, becoming 

 strict, and with the sessile fruiting calyx appressed : this at most 2 lines long, tliickly beset 

 toward the base with stout reflexed bristles (of a line or less in length), the tips of some 

 of them curving: nutlet ovate-acuminate or ovate-lanceolate, very smooth and shining, 

 fully a line long, much surpassing the subulate gynobase and style, affixed to the latter 

 only by the lower half or third of the narrow ventral groove. — Proc. Am. Acad. x. 58, & 

 Bot. Calif, i. 526. Myosotis flaccida, Hook. & Am. Bot. Beech. 369, ex Benth., not Dougl. 

 Krynitzkia leiocarpa, Benth. PI. Hartw. (no. 1872), 326, not Fisch. & Meyer. — Common in 

 W. California. (Not seen from Oregon.)
