exceeding the calyx, and the throat appendaged. {Roots perennial, long 

 and deep, yielding a red dije.) 



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



ample limb, the lobrs 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); 

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

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

 westAvard. April - June. 



3. L. eaneseens, Lehm. (Plxcoon 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 doiuny beneath and roughish with close appressed 

 hairs above ; ^ou^ers sessile; corolla naked at the base within; fruiting calyx 

 (3" long) barely tivice 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, Michx. Erect or diffusely branched from the 

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

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

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

 Avith inconspicuous or small and pale corollas, Avithout crests, and the pedicels 

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

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

 Mich, to Dak. and Tex., and AvestAvard. 



8. ONOSM ODIUM, Michx. False Gromavell. 



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

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

 lobes converging or bareh^ spreading. Anthers oblong-linear or arroAv- 

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

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

 minute, not holloAAed out. — Chiefly perennial herbs, coarse and hispid, AA-ith 

 oblong and sessile ribbed-veined leaves, and Avhite, greenish, or yelloAvisIi 

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

 mer. — Our species belong to true 0NOSMODiU3r, with smooth included anthers 

 on very short filaments ; the corolla rarely tAvice the length of the calyx. 

 (Named from the likeness to the genus Onosma, Avhich name means ass-smell.) 



1. O. Virginianum, DC. Clothed (dl ever idth harsh and rigid ap- 

 pressed short bristles ; stems rather slender (1-2^ higli) 5 leaves narrowly 

 oblong, or oblong-lanceolate (1 - 2|' long), the loAver narrowed at base ; lobes 

 of the narrow corolla lance-aicl-shaped , sparingly bearded outside Avith long 

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



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