216 OAMOPETALOUS EXOGENS 



Perennial. Root large, red. <Sfem about a foot high, several from the same root, 

 Sometimes trichotomously branched above, hoary with spreading hairs. Leave* 

 bout an inch and half long, clothed with appressed hairs. Cm-Ma with a slight 

 pubescent ring on the inside, at bottom. 

 Hob, Great Valley : rare. Fl. May. Fr. June. 



Obs. This pretty little plant is quite rare, here. The root was 

 used, by the Aborigines, for staining red. 



314. MYOSO V TIS, L 



[Gr. Mys, myos, a mouse, and ous, otos, an ear ; from the form of the leaves.] 

 Corolla salver-form; lobes rounded, convolute in the bud! tub* 

 about as long as the calyx ; throat with 5 short arching appendages 

 opposite the lobes. Stamens included. Nutlets smooth, somewhat 

 compressed. Flowers small, in terminal racemes, mostly without 

 bracts. 



1. IH. liixa, Lehm. Biennial ; stems ascending, rooting near the 

 base, terete, branching ; leaves lance-oblong, rather obtuse ; pedicels 

 about twice as long as the calyx. 



M. palustris. Fl. Cestr. ed. 2. p. 120. not of Withering. 

 LOOSE MYOSOTIS. Scorpion-grass. Forget-me-not. 



Stem 1 to 2 feet long, slender, smoothish. Leaves 1 to 3 inches long, upper ones 

 geefiile, lower ones often petiolate. Racemes terminating the branches, sometimes 

 in pairs, elongating, secund, at first recurved. Corolla bright blue, the throat 

 closed with yellow connivent scales ; border nearly flat. 

 Hob. Swampy rivulets, and springs: frequent. Fl. May. Fr. July. 



Obs. This seems to have been generally mistaken for the M. 

 palustris, With, or true " Vergiss mein nicht," of the Germans, to 

 which, indeed, it bears a close resemblance. 



2. lH. Stricta, Link. Annual ; stem erect, nearly simple ; leaves 

 oblong, or oval-lanceolate, rather acute ; pedicels about as long as 

 the calyx. 



M. arvensis. Fl. Cestr. ed. 2. p. 120. 

 UPRIGHT MYOSOTIS. 



Plant greyish-pubescent. Stem at first nearly simple, at length branching, 3 *o 

 6 (and finally sometimes 12) inches high. Leaves half an inch to an inch long, 

 sessile, scabrous, the lower ones often lance-obovate, obtuse, and petiolate. 

 Racemes terminal, at first short, and the flowers crowded, finally much elongated, 

 bifarious (not secund). Corolla very small, white, or sometimes pale blue; border 

 somewhat erect. 

 Hob. Dry hills, and serpentine rocks : not common. Fl. May. Fr. July. 



Obs. This species is usually very diminutive, when the flowers 

 begin to appear; but the racemes finally stretch up sometimes to 

 the height of 12 or 15 inches. 



315. MERTEtfS'IA, Roth. 



[Dedicated to Prof. F. C. Mertens, of Bremen.]

 obscurely lobed; throat naked, or with 5 small folds therein. 

 Stamens and style rather shorter than the corolla. Nutlets ovoid, 

 smoothish, fixed obliquely by the internal angle. Smooth perennials : 

 flowers purplish-blue, large, in terminal (at first corymbose) racemes.
