leaves oblanceolate, obtuse; stem leaves mostly oblong or oblong-lanceolate, nar- 

 rowed to the sessile base, 1-4 cm. long; calyx-lobes equal, erect, or connivent in 

 fruit, triangular-lanceolate, acute, about as long as the tube; corolla blue or white, 

 the limb concave, 2-3 mm. broad; nutlets convex on the outer side, somewhat keeled 

 on the inner. In fields, N. B. to Ont. and Minn., south to W. Va. Perhaps not 

 indigenous. Also in Europe. June-Aug. 



4. Myosotis versicolor (Pers.) Reichenb. YELLOW AND BLUE SCORPION- 

 GRASS. (I. F. f. 3041.) Annual, hirsute-pubescent, often branched above; stems 

 1-3 dm. high. Leaves oblong, obtuse or obtusish, sessile, or the lower spatulate 

 and narrowed into margined petioles; pedicels erect; calyx-lobes linear-lanceolate, 

 erect or connivent in fruit, longer than or equalling the tube; corolla pale yellow 

 changing to violet or blue, its limb about 2 mm. broad; nutlets convex on the 

 cuter, slightly keeled on the inner side. In fields and along roadsides, southern 

 N. Y. to Del. Nat. from Europe. May-July. 



5. Myosotis collina Hoftm. EARLY MYOSOTE. Similar to the two preced- 

 ing species, usually much branched from the base, rarely over 1.5 dm. high. 

 Leaves oblong, or the lower spatulate, mostly obtuse; pedicels rarely over 2 mm. 

 long, the segments not closed over the fruit. Fields, Me. to Ont., Mass, and N. Y. 

 Adventive from Europe. May-June. 



6. Myosotis Virginica (L.) B.S.P. SPRING SCORPION-GRASS. (I. F. f. 

 3042.) Hirsute-pubescent or hispid, 0.7-3 tlm - high, the branches erect. Leaves 

 oblong or linear-oblong, sessile, 0.6-2.5 cm - lng, obtuse, or the lower spatulate 

 and narrowed into short petioles; racemes strict, dense; pedicels ascending or 

 erect, or slightly spreading at the apex, shorter than the fruiting calyx; calyx 

 somewhat 2-iipped, unequally 5 -cleft, the lobes lanceolate, acute, longer than the 

 tube, connivent in fruit, very hispid; corolla limb 3 mm. broad or less; nutlets con- 

 vex on the back, slightly keeled and margined on the inner side. On dry hills 

 and banks, Me. to Ont., Minn., Ga. and Tex. April-June. [M. verna Nutt.j 



7. Myosotis macrosperma Engelm. SOUTHERN SCORPION-GRASS. Similar 

 to M. Virginica, but usually larger, the slender branches ascending or spreading; 

 racemes with comparatively few and distant fruiting calyces; pedicels ascending 

 or recurved, about equalling the fruiting calyx. D. C. to Fia., Ky., Ark. and 

 Tex. April-May. 



it. LITHOSPERMUM L. 



Pubescent hirsute or hispid herbs, with alternate entire leaves, the flowers in 

 leafy-bracted spikes or racemes. Calvx 5 -parted or 5 -cleft, the segments or lobes 

 narrow. Corolla funnelform or salverform, 5-lobed. naked, pubescent or crested in 

 the throat, the tube sometimes pubescent at the base within. Stamens 5, included, 

 inserted on the throat of the corolla; filaments short. Stigma capitate, or 2-lobed. 

 Nutlet? 4, or fewer, erect, white, smooth and shining, or brown and wrinkled, at- 

 tached bv their bases to the nearly flat receptacle, the scar of attachment not con- 

 cave. [Greek, stone seed, from the hard nutlets.] About 40 species, of the 

 northern hemisphere, a few in S. Am. and Africa. Besides the following, some 7 

 others occur in the southern U. S. 



Corolla white or yellowish, its tube shorter than or equalling the calyx; flowers distant. 

 Nutlets brown, wrinkled and pitted; annual or biennial. i. L. arvense. 



Nutlets white, smooth and phininsr; perennials. 



Leaves lanceolate, acute ; ni'tlets ovoid. 2. L.officinale. 



Leaves ovate, acuminate; nutlets globose-ovoid. 3. L. latifolium. 



Corolla dull yellow, its tube longer than the calyx ; leaves lanceolate; flowers dense, 



4. L.pilosum. 



Corolla bright yellow, its tube much longer than the calyx; flowers dense. 

 Corolla-lobes entire ; flowers all complete. 



Hispid-pubescent: corolla-tube bearded at the base within. 5. L. Gmelini, 

 Hirsute, somewhat canescent: corolla tube not bearded at the base within.
