BORRAGINACE^E. (BORAGE FAMILY.) 821 



lanceolate (l'-2| ; long), the lower narrowed at the base; corolla rather longer 

 than the calyx (3" long) ; the lobes lanceolate-awl-shaped, bearded with long bristles 

 outside; anthers oblong-arrow-shaped, on very short flattened filaments. (O. 

 hispidum, Michx. Lithospermum Virginianum, L.!) Banks and hill-sides, 

 S. New England to Virginia and southward. June - Aug. 



2. O. Carolinianum, DC. (excl. syn. Michx.) Clothed all over with 

 long and spreading bristly hairs; stem stout, upright (3 -4 high) ; leaves ovate- 

 lanceolate or oldong-lancedate, acute ; corotta twice the length of the calyx ; the lobes 

 deltoid-ovate, obtusish; anthers oblong, longer than the narrow filaments. (O. 

 molle, Beck, &c. Lithosp. Carolinianum, Lam.) Kiver-banks, W. New York, 

 Wisconsin, Virginia, and southward. June, July. Stouter and larger-leaved 

 than the last, thickly clothed with less rigid but long and shaggy whitish hairs. 

 Lobes of the corolla more or less hairy on the back, appearing slightly heart- 

 shaped by the inflexion of the sinuses. This has been confounded by some 

 authors with No. 1 ; by others with No. 3, which it most resembles. 



3. O. niolle, Michx. Hoary with Jine and close strictly oppressed hairs ; 

 leaves oblong-ovate, obtusish, soft-downy underneath; corolla longer than the calyx, the 

 lobes lance-ovate or triangular, acute ; anthers linear, much longer than the verti- 

 cally dilated filaments. Dry grounds, Illinois and southward. Corolla rathei 



-larger than in the last; the lobes more or less hairy along the middle. 



5. L.ITHOSPERMUM, Tourn. GROMWELL. PUCCOON. 



Corolla funnel-form, or sometimes salver-shaped ; the open throat naked, or 

 with a more or less evident transverse fold or scale-like appendage opposite each 

 lobe ; the spreading limb 5-cleft ; its lobes rounded. Anthers oblong, almost 

 sessile, included. Nutlets ovate, smooth or roughened, mostly bony or stony, 

 fixed by the base ; the scar nearly flat. Herbs, with thickish and commonly 

 red roots, sessile leaves, and axillary or often spiked or racemed leafy-bracted 

 flowers (occasionally of 2 forms as to stamens and style, as in Oldenlandia, p. 

 171, &c.). (Name compounded of Xi'tfos, stone, and orrep/ia, seed, from the hard 

 nutlets.) 



$ 1. Nutlets tubercled or rough-wrinkled and pitted, gray and dull: throat of the 

 (nearly white) corolla destitute of evident folds or appendages. 



1. L*. ARVENSE, L. (CORN GROMAVELL.) Minutely rough-hoary; stems 

 erect (6' - 12' high) ; leaves lanceolate or linear, veinless ; corolla scarcely longer 

 than the calyx. (J) Sandy banks and road-sides, New England to Pennsyl- 

 vania and Michigan. May- Aug. (Nat. from Eu.) 



2. Nutlets smooth and shining, mostly white like ivory, occasionally doited with pores: 

 corolla in our species greenish-white or cream-color, small, with 5 small but distinct 

 pubescent scales in the throat. ( Root perennial.) 



2. L.. aiiifiisii folium, Michx. Minutely and slightly hoary, roughish, 

 much branched, erect or spreading (6' -15' high) ; leaves linear, rigid, \-nerved, 

 corolla not longer than the calyx ; the short peduncles in fruit mostly recurved ;
