throat : filaments equalling or longer than the oblong or somewhat arrow-shaped 

 anthers. Style long and thread-form. Nutlets ovoid, fleshy when fresh, smooili 

 or wrinkled, obliquely attached next the base by a prominent internal angle ; the 

 scar small. — Smooth ! or soft-hairy perennial herbs, with pale and entire leaves, 

 and handsome purplish-blue (rarely white) flowers, in loose and short panicled 

 or corymbed racemes, only the lower ones leafy-bracted : pedicels slender. 

 (Named for Prof. Martens, an early German botanist.) 



§ 1. Corolla perfectly naked in the throat ; the broad trumpet-mouthed limb slightly 5 

 lobed : filaments narrow, much longer than the anthers. 



1. M. Virginica, DC. (Virginian Cowslip or Lungwort.) Very 



smooth, pale, erect (l°-2° high) ; leaves thin, obovate, veiny, those of the root 

 (4' -6' long) petioled; corolla trumpet-shaped, 1' long, many times exceeding 

 the calyx, rich purple-blue, rarely white. (Pulmonaria Virginica, L.) — Allu- 

 vial banks, W. New York to Wisconsin, Virginia, Kentucky, and southward. 

 May. — Cultivated for ornament. 



§ 2. Corolla with 5 glandular folds or appendages at the throat ; the limb more deeply 

 lobed : filaments shorter and broader. 



2. ]?I. maritime, Don. (Sea Lungwort.) Spreading or decumbent, 



smooth, glaucous; leaves fleshy, ovate or obovate, the upper surface becoming pa- 

 pillose; corolla bell-fnnnel-form, twice the length of the calyx (3" long) ; nutlets 

 smooth, flattened. — Sea-coast, Plymouth, Massachusetts (Russell), Maine ? and 

 northward. (Eu.) 



3. M. pailiCIllata, Don. Roughish and more or less hairy, erect (1°-2 C 

 high), loosely branched; leaves ovate and ovate-lanceolate, taper-pointed, thin; co- 

 rolla somewhat funnel-form, 3-4 times the length of the hairy calyx (\' long) ; 

 nutlets rough-wrinkled when dry. (Probably also M. pilosa, DC.) — Shore of 

 Lake Superior, and northward. 



7. HIYOSOTIS, L. Scorpion-Grass. Forget-me-not. 



Corolla salver-form, the tube about the length of the 5-toothed or 5-cleft calyx, 

 the throat with 5 small and blunt arching appendages opposite the rounded 

 lobes ; the latter convolute in the bud ! Stamens included, on very short fila- 

 ments. Nutlets smooth, compressed, fixed at the base ; the scar minute. — Low 

 and mostly soft-hairy herbs, with entire leaves, those of the stem sessile, and 

 with small flowers in naked racemes, which are entirely bractless, or occasion- 

 ally with one or two small leaves next the base, prolonged and straightened 

 in fruit. (Name composed of pvs, mouse, and ovs, euros, eeir, in allusion to the 

 aspect of the short and soft leaves in some species : one popular name is 

 Mouse-ear.) 



* Calyx open in fruit, its hairs oppressed, none of them hooked nor glandular . 

 1. M. palustris, With. (True Forget-me-not.) Stems ascending 

 from an obliquely creeping base (9'-20' high), loosely branched, smoothish ; 

 leaves rough-pubescent, oblong-lanceolate or linear-oblong; calyx moderately 

 5-cleft, shorter than the spreading pedicels ; corolla (rather large in the genuine 

 plant) pale blue with a yellow eye. 1J. — Cultivated occasionally.— Varies into
