 Leaves smaller, ovate-lanceolate; corolla-lobes usually less than one-half the 

 length of the tube; nutlets larger. On plains, Manitoba and the N. W. Terr, to 

 111., Kans.. Tex. and Utah. May- July. 



3. Onosmodium Virginianum (L.) DC. Virginia False Gromwell. (I. 

 F. f. 3052.) Appressed-hispid with stiff hairs; stem 3-8 dm. high. Leaves 

 oblong, oval, or oblong- lanceolate, sessile, 2-8 cm. long, or the lower oblanceolate, 

 acutish and narrowed into petioles; calyx-segments linear-lanceolate, acuminate; 

 corolla cylindric or nearly so, about 8 mm. long, the lobes lanceolate, acuminate, 

 nearly as long as the tube, strigose without; nutlets ovoid, obtuse or obtusish, 

 2-3 mm. long. In thickets or on hillsides, N. Eng. to Fla., Kans. and Tex. 

 May-July. 



13. SYMPHYTUM L. 



Erect rough hairy perennial herbs, with mucilaginous roots, alternate entire 

 leaves, the uppermost tending to be opposite, the lower long-petioled. Flowers 

 yellow, blue, or purple, in terminal scorpioid racemes. Calyx deeply 5-cleft. 

 Corolla tubular to campanulate, slightly dilated above, 5-lobed, the lobes short, the 

 throat with 5 crests below the lobes. Stamens 5, included, inserted on the corolla- 

 tube. Style filiform. Nutlets 4, obliquely ovoid, wrinkled, inserted by their 

 bases on the flat receptacle, the scar of the attachment broad, concave, dentate. 

 [Greek, grow-together, from its supposed healing virtues.] About 15 species, of 

 the Old World. 



Pilose-pubescent. 1. S. officinale. 



Stem bristly-papillose. 2. S. asperimum. 



i. Symphytum officinale L. Comfrey. Healing-herb. (I. F. f. 3053.) 

 Roots thick, deep; stem 6-9 dm. high. Leaves lanceolate, ovate-lanceolate, or

 4-8 mm. long; calyx segments ovate or ovate-lanceolate, acute or acuminate, much 

 shorter than the corolla; corolla yellowish or purplish. 12 mm. long; nutlets brown, 

 shining. 4 mm. high. In waste places. Newf. to Minn., south to Md. Nat. or 

 adventive from Europe. June-Au^. 



2. Symphytum asperimum Sim=. Rough Comfrey. Similar to the pre- 

 ceding, but the stem and branches very rough -bristly. Leaves ovate to ovate- 

 lanceolate, rough; calyx-segments subulate. In waste places, N. Y. and Mass.
