lanceolate (l'-2i'long), the lower narrowed at the 1>ase ; corolla rather longer 

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

 outside; authors oblong-arrow-shaped, on very short flattened filaments. ((). 

 hispiduni, M/'chx. Lithospermum Virginianura, 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-

 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.

 leaves oblong-evate, 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 rather 

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

 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 Olderilandia, p. 

 171, &c.). (Name compounded of \i0os, stone, and <rrrpp,a, seed, from the hard 

 nutlets.) 



1. Nutlets tuberded 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 GROMWELL.) Minutely rough-hoary; stems
