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 woolly-bearded at the base inside (limb 8 -12" broad); 

 flowers distinctly pnlnin-li'd, 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. (PrccooN of the Indians.) Softly hairy and

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

 hairs above ; flowers sessile; corolla naked at the base icithin ; fruiting calyx 

 (3" long) luircly twice the length of the nutlets. Plains and open woods, in 

 sandy soil, ( )ut. to Ya., Ala., and westward. M;iy. 



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

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

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

8. ONOSM ODIUM, Michx. FALSE GKOMWELL. 



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 barely spreading. Anthers oblong-linear or arrow- 

 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 hollowed out. Chiefly 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 authors 

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

 (Named from the likeness to the genus Onosina, which name means ass-smell.)
