PEKTANDRIA. MOXOGYNIA. 115 



peculiar to Arabia, 1 to Japan, 1 to Siberia, and another to 

 the summit of mount Lebanon, m Syria. 



IT 3. PULMONARIA. X. (Lungwort.) 



Calix prismatic-ppntaj^onal. Corolla funnel- 

 formed, somewhat 5-lobed, orifice open. Stig- 

 ma emarginate. 



Flowers almost disposed in terminal corymbs, some- 

 times racemose. Leaves in the American species and m 

 the P. maritima smooth and glaucous, calix short, about 

 halftlie lengih of the corolla tube. (Mertensia Per- 

 soon.) 



Species. 1. P . xii^iniccu '2. panieulata. Z. * marginata . 

 Small, glabrous, erect; leaves hispid on the margin, on the 

 lower part of the stem oblong'-spaihulate op ^)blong'-ovate, 

 upper leaves ovate, acute, semiamplexicanle; flowers sub- 

 paniculate; fasciculi few-flowered, axillary and termmaU 

 calix acute, ab'ut half ihe length of the corolla tube. 



P. lanceolata. Pursh, Flor. Am. 2. p. 729- 



Perenniah b:em nearly erect, and somewhat branched, 

 scarcely a foot ligh. Radical leaves peciolate, atem leaves 

 sessile, uppermost semian.plexicaule, all glabrous, glau- 

 cous, and somewhat carnose. Fascicles or ramuli, pedi- 

 cellate, a little longer than the lea^xs, 4, 5. 8, or more 

 flowered. Cahx 5-parted, smootl-, acute, segments some- 

 what hispid on the margin. Corolla funnel rormea,.mucli 

 like that of P. virgi7iica, and of the same colour, but 

 smaller, lobes entire. Stamina seated around the orifice 

 of the tube. 



Nearly allied to P. virginica, and also probably to the P. 

 paniculatUy but the leaves are never acuminated or hairy, 

 but perfectly smooth, except ©n the margin where there 

 are afew scattered hooked» hispid bans, often oiilv visible 

 in a dried state. The name of lanceolata is so very inap- 

 plicable that it appeared 'o me necessary to alter it. 



Oi and hills n^ ar the confluence of Teeton river, Mis= 

 souri. Flowering in June. 



4. panicxdata. 5. sibirica. 



The only 3 genuine species of P ultnonaria described 

 are confined to Europe; the American ^pecics all arrange 

 under the subdivision Meriensia of Persoon.

Calix deeply 5-parted. Corolla somewhat tu^ 

 bular-cacipanulate; orifice naked; border vea-
