I'illous Mertensia. PI. \ to 1 foot. 



12 M. PILOSA ; stems erect, more or less rough from strigae, 

 like the upper surfaces of the leaves, but the under surfaces of 

 the leaves, and margins, and bases of the stems are beset with 

 longer, softer, slrigose pili ; radical leaves on long petioles, sub- 

 cordate-ovate, acute, membranous : c. uline leaves sessile, nar- 

 rower ; racemes cymose, panicled, terminal, twin. 1 . H. 

 Native of America, in Eschscholz Bay, beyond Beering's 

 Straits. Stems simple or branched, many from the same root. 

 Radical leaves S\ inches long, and 2 broad. Pedicels drooping. 

 Calycine segments narrow-lanceolate, acuminated. Corolla 1 to 

 1-y inch long, pale blue, glabrous outside, but pilose inside ; 

 tube slender ; limb campanulate ; throat furnished with minute, 

 arched, glandular, fleshy processes. Nuts granular, wrinkled. 

 Small fleshy processes of the throat have been observed in this, 

 M. denticulata, M. maritima, and M. Dahurica. 



Pilose Mertensia. PI. 1 \ to 2 feet. 



18 M. PARVIFLORA ; plant quite glabrous, glaucous; stems 

 procumbent, much branched ; leaves oval-spatulate, abruptly 

 acuminated, fleshy ; peduncles lateral, 1 -flowered ; corolla 

 hardly twice as long as the calyx. If. H. Native of New 

 England and Canada, on the sea shore. Pulmonaria parviflora, 

 Michx. fl. amer. bor. 1. p. 133. Pursh, fl. 1. p. 131. Pulmo- 

 naria maritima of all American authors. Flowers small, blue. 



Small-flowered Mertensia. Fl. July. Clt. 1827. PL pro- 

 cumbent. 



14 M. MARITIMA (Link, handb. erk. der. gew. 1. p. 58.) 

 plant glabrous, glaucous ; stems procumbent, branched ; leaves 

 ovate, bluntish, fleshy; calyx glabrous. 3. H. Native of the 

 north of Europe, on the sea shore ; as of Britain, Norway 

 Iceland, Greenland, Lapland, &c. Pulmonaria maritima, Lin.

 fibres. Leaves ovate or oblong, acutish ; upper ones half stem- 

 clasping. Flowers erect, disposed in terminal, corymbose ra- 

 cemes. Calycine segments oval, acutish. Corolla blue, twice 

 or thrice as long as the calyx ; limb subcampanulate. This 

 plant is a great ornament to the sandy sea coasts in Scotland 

 and the north of England. The plant is by some called the 

 Oyster plant, from the similarity of its taste to that of oysters. 



Sea Mertensia. Fl. July. Britain. PL procumbent. 



Cult. All the species of Mertensia are elegant, hardy border 

 plants, much admired by gardeners for their brilliant blue 

 flowers, which are of a reddish hue before expansion. The 

 first twelve species do best in a peat border, but they will also 

 grow in common garden soil ; these are best fitted for the front 

 of flower borders. The last two species, being natives of the 

 sea coast, require, when cultivated, to be grown in pots, in a 

 mixture of sand and peat, or sand altogether, and placed among 

 other alpine plants ; but to keep them in vigour, even in this 

 situation, they require to be refreshed occasionally with salted 

 water.

 this flower.) Tourn. inst. t. 50. Lin. gen. no. 1 89. Schreb.

LIN. SYST. Pentdndria, Monogynla. Calyx of 5 unequal 

 sepals. Corolla tubular, with a naked throat. Anthers hastate, 

 spirally twisted at the base of the lobes, where they are connected. 

 Nuts 2, 2-celled, imperforated at the base, fixed to the bottom 



of the calyx. Glabrous glaucous plants, with terminal, leafy 

 racemes of tubularly campanulate, drooping, variegated flowers. 



1. Corolla 5- toothed: teeth reflexed, or spreading. 



1 C. MA V JOR (Lin. spec. 195.) stem branched ; leaves cordate- 

 ovate, denticulately ciliated ; corollas ventricose at top, 5-tooth- 

 ed : teeth very short, acuminated, reflexed. Q. H. Native of 

 the south of Europe, Barbary, and Siberia. Scop. fl. earn. ed.

 tongue-shaped, emarginate, attenuated at the base ; superior 

 ones blunt ; the floral ones sometimes purplish-green, all fleshy, 

 glaucous, and stem-clasping, glabrous above, densely beset with 

 white dots, rough beneath. Pedicels shorter than the floral 

 leaves. Corolla yellow at bottom and purple at top. This is 

 one of the most common herbs all over Italy : hence Virgil's 

 expression of " Cerinlhce ignobile gramen." There is abundance 

 of honey juice in the tube of the corolla, for which reason it is 

 much resorted to by bees ; the plant is therefore peculiarly 

 proper to be planted near Apiaries.

 ing, acute. . H. Native of the Peloponnesus ; and of Caria,
