BORAGE FAMILY. 245 



late, rather obtuse, rough-hairy ; nutlets each with a double row of 

 prickles on the margins, and tubercled on the back. 



Stickseed. Narrow-leaved Stickseed. 



Annual or biennial. Stem a foot or more in height, covered with greyish spreading 

 hairs, simple below. Leaves 1-2 inches long, very hairy ; the hairs mostly tuberculate 

 at the base. Flowers in leafy racemes, the pedicels very short. 



Waste places. Native of Europe. July. 



Obs. Rather common in some localities. The nutlets adhere to the 

 coats of sheep and cattle, and on this account the weed is a troublesome 

 one. 



4. CYNOGLOS'SUM, Tournef. HOUND 'S-TONGUE. 



[Greek, Kyon, a dog, and Glossa, a tongue ; from the form of the leaves.] 



Corolla funnel-form the tube nearly as long as the calyx ; throat closed 

 by 5 obtuse scales ; limb 5-lobed ; the lobes very obtuse. Stamens in- 

 cluded. Nutlets depressed or convex, oblique, fixed near the apex to the 

 base of the style, roughened all over with short barbed or hooked 

 prickles. Coarse herbs with a strong unpleasant odor, and mostly panicled 

 racemes which are naked above, but usually bracted at the base. Lower 

 leaves petioled. 



1, C, Moriso'ni, DC. Stem erect, somewhat hispid, divaricately 

 branched at summit ; leaves ovate, lanceolate, acuminate, narrowed at 

 base ; racemes somewhat in pairs, with the rachis villous ; pedicels 

 finally reflexed ; fruit densely covered with uncinate prickles. 



MOKISON'S CYNOGLOSSUM. Beggar's Lice. 



Root annual. Stem 2-4 feet high. Leaves 3-4 inches long, acute at each end, scabrous, 

 the lower ones petiolate the upper ones subsessile. Racemes terminating the slender 

 divaricate branches, mostly dichotomous ; pedicels about as long as the fruit. Corolla 

 bluish-white, small. 



Fence-rows and borders of thickets : Northern and Middle states. Fl. July. Fr. 

 October. 



Obs. The slovenly farmer is apt to get a practical acquaintance with 

 this obnoxious weed, in consequence of its racemes of bur-like fruit en- 

 tangling the manes of his horses, and the fleeces of his sheep. 



2. C. officina'le, L. Softly pubescent ; stem paniculate above, leafy ; 

 upper leaves lanceolate, closely sessile by a rounded or slightly heart- 

 shaped base ; racemes nearly bractless ; nutlets flat on the broad upper 

 face, somewhat margined. 



OFFICINAL CYNOGLOSSUM. Hound's-tongue. 



Biennial. Stem about 2 feet high. Radical leaves 9-12 inches in length, lance oblong, 

 petiolate ; stem leaves 3-6 inches long. Racemes 2-5 inches long, mostly erect, secund 

 pedicels %- y z an inch in length corolla reddish or purplish brown, (rarely white). 



Waste places and pastures. Native of Europe. May -July. 



Obs. Troublesome in the same manner with the preceding species. 

 The disagreeable odor of the plant has been compared to that of nests 

 of young mice.
