to a cor Jjite sliape, as may be seen by the detached leaves represen- 

 ted in the plate. The figure itself, however, represents a specimen 

 of the spontaneous growth of this country. Tiie leaves which are 

 the part directed for use, are inodorous, but in their recent state 

 manifest a shglitly astringent and mucilaginous taste ; hence it 

 seems not wholly without foundation, that they liave been supposed 

 to be denuilcent and pectoral. The name, Puhnonaria, seems to 

 have oi'iginated rather fr(_)m the speckled appearance of the leaves, 

 (they resembling that of the huigs,) than from any intrinsic quality 

 wliich experience has discovei-ed to be useful in pulmonary com- 

 plaints. 



Puhnonaria angustifolia. Narrow-leaved Lungwort. In this 

 species tlie leaves are mucli narrower than those of the first sort, 

 and covered with soft hairs, not spotted ; the stalks rise about a foot 

 m height, and have narrow leaves, nearly the same shape of those 

 of the follo\ving species, but a little smaller and almost embracing. 

 The flowers aa"e produced in bunches on the top of the stalks, of a 

 beautifid blue color. Native of Sweden. 



Palinunary Virginka. Virginian Lungwort. This species has 

 a peremiial, thick, tleshy root, sending out many small fibres ; the 

 stalks a foot and a half high, dividing at the top into several short 

 branches ; the leaves near the root are four or five inches long, and 

 from two to three mches broad, smooth, of a light green, and on short 

 footstalks ; those upon the stem diminish in their size upwards ; 

 they are of the same shape and sessile. Every small branch at the 

 top of the stalk is termmated by a cluster of flowers, each standing 

 upon a separate short peduncle. The most common color of these 

 flowers is blue ; but there are some purple, others red, and some 

 white. They appear in April, and if they have a shady situation, 

 continue in beauty the most part of May. It grows upon momitains 

 in almost every part of North America. 



Pulmonaria mollis. Soft Lmigwort. This species rises not 

 more than a foot in height ; calyxes rather longer than the tube of
