BORAGINACEJE. (BORAGE FAMILY.) 
4. 03M0SM0I>IUM, Michx. False Gromwell. 
Corolla oblong-tubular, seldom twice the length of the 5-parted 
erect calyx, with 5 erect lobes, naked in the throat, the sinuses 
minutely hooded-inflexed. Anthers included, almost sessile, ar¬ 
row-shaped, apiculate. Style much exserted, smooth. Nutlets 
ovoid, smooth and shining, fixed by a flat base (closed). — Peren¬ 
nial herbs, with oblong and sessile nerved leaves, and yellowish- 
white flowers in terminal and one-sided, at length elongated and 
erect, spiked racemes, leafy-bracted. (So called from the near 
resemblance to the genus Onosrna.) 
1. O. VirgiumilUIll, DC. Clothed all over with harsh and rigid 
oppressed bristles; stems rather slender (l°-2° high); leaves oblong , 
or oblong-lanceolate, the lower narrowed at the base; corolla rather 
longer than the calyx ; the lobes lanceolate-awl-shaped , bearded with 
long bristles outside. (O. hispidum, Michx. Lithospermum Virgini- 
anum, L. /) — Banks and hill-sides, S. New England to Penn, and 
southward. June-Aug.— Leaves 1 ; -2<P long. Corolla smaller 
than in the others : anthers smooth, as also in Nos. 2 and 3, oblong- 
arrow-shaped, on very short flattened filaments. 
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 oblong-lanceolate , acute; corolla 
twice the length of the calyx ; the lobes deltoid-ovate , obtusish ; anthers 
oblong, longer than the narrow filaments. (O. molle, Beck , 
Lithosp. Carolinianum, Lam.) — River-banks, W. New York and 
Michigan to Virginia and southward. June, July. — Stouter and 
larger-leaved than the last, thickly clothed with less rigid 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 very distinct species has been confounded by some preceding 
authors with No. 1, by others with No. 3. 
3. O. molle, Michx. Hoary with fine and close strictly oppress 
ed hairs ; leaves oblong-ovate , obtusish, soft-downy underneath ; coro 
longer than the calyx, the lobes lanceolate-ovate or triangular, acute, 
anthers linear, much longer than the vertically dilated filaments. 
Probably confined to the Western States; it abounds in Tennessee 
and Illinois, and probably extends to Ohio.— Corolla rather larger 
than in the last: the lobes more or less hairy along the middle. 
5. LITHOSPERMUM, Tourn. Gromwell. 
Corolla funnel-form, or rarely salver-form ; the tube equalling or 
exceeding the 5-parted calyx; the {hroat open, mostly furnishe
