366 BORRAGINACE^. (bORAGE FAMILY.) 



exceeding the calyx, and the throat appendaqed, {Roots pei'ennial, long 

 and deep, yielding a red dye.) 



* Corolla-tube one half to twice longer than the calyx, not much longer than the 



ample limb, the lobes entire; appendages little if at all projecting. 



2. L. hirtum, Lehm. Hispid with bristly hairs (1-2° high); stem- 

 leaves lanceolate or linear, those of the flowering branches ovate-oblong, 

 bristly-ciliate ; corolla icoolly-bearded at the base inside (limb 8-12" broad); 

 Jiowers distinctly peduncled, crowded, showy ; fruiting calyx {^' long) 3-4 

 times longer than the nutlets. — Pine barrens, etc., N. Y. to Minn., south and 

 westward. April - June. 



3. L. canescens, Lehm. (Puccoox of the Indians.) Softly hairy and 

 more or less hoary (6-15' high); leaves obtuse, linear-oblong, or the upper 

 ovate-oblong, more or less downy beneath and roughish with close appressed 

 hairs above ; y?oire?-s sessile; corolla naked at the base within ; fruiting calyx 

 (3" long) barely tioice the length of the nutlets. — Plains and open woods, in 

 sandy soil, Ont. to Va., Ala., and westward. May. 



* * Corolla-tube in well-developed flowers 2-4 times the length of the calyx and 



of its erose-toothed lobes, and the appendages conspicuous and arching ; later 

 flowers small, cleistogenous. 



4. L. angustifolium, Miclix. Erect or diffusely branched from the 

 base, 6-18' high, minutely rough-strigose and hoary; leaves linear; flowers 

 pedicelled, leafy -bracted, of two sorts; the earlier large and showy (corolla- 

 tube 8-18" long), the later and those of more diffusely branching plants, 

 with inconspicuous or small and pale corollas, without crests, and the pedicels 

 commonly recurved in fruit ; nutlets usually punctate. (L. longiflorum, 

 Spreng.; the long-flowered form.) — Dry and sterile or sandy soil, Ind. and 

 Mich, to the Dakotas and Tex., and westward. 



8. OWOSMODIUM, Michx. False Gromwet.l. 



Calyx 5-parted ; the divisions linear and erect. Corolla tubular, or tubular- 

 funuel-form, not crested (the sinuses minutely hooded-inflexed), the 5 acute 

 lobes converging or barely spreading. Anthers oblong-linear or arrow- 

 shaped, mucronate, inserted in the throat. Style thread-form, much ex- 

 serted. Xutlets bony, ovoid, smooth, erect, fixed by the base; the scar 

 minute, not hollowed out. — Cliiefly perennial herbs, coarse and hispid, with 

 oblong and sessile ribbed-veined leaves, and white, greenish, or yellowish 

 flowers, in at length elongated and erect leafy raceme-like clusters; in sum- 

 mer. — Our species belong to true Onosmodium, with smooth included anthers 

 on very short filaments ; the corolla rarely twice the leugth of the calyx. 

 (Xamed from the likeness to the genus Onosma, which name means ass-smell.) 



1. O. Virginianum, DC. Clothed all over icith harsh and rigid ap- 

 pressed short bristles; stems rather slender (1-2° high); leaves narroivly 

 oblong, OT oblong-lanceolate (1 -2^' long), the lower narrowed at base; lobes 

 of the narrow corolla lance-awl-shaped, sparingly bearded outside with long 

 bristles. — Banks and hillsides, N. Eng. to Ela., Mo., and La. 



2. O. Carolini^num, DC. Shaggy all over with long and spreading 

 bristly hairs; stem stout, upright (2-4° high); leaves ovate-lanceolate or
