Calix prismatic-pentagonal. Corolla funnel- 
formed, somewhat 5-lobed, orifice open, Stfig- 
ma emarginate. 
Flowers almost disposed in terminal corymbs, some- 
times racemose. Leaves in the American species and in 
the P. maritima smooth and glaucous, calix short, about 
half the length of the corolla tube. (Mertrensia Per-

Small, glabrous, erect; leaves hispid on the margin, on the 
lower part of the stem oblong-spathulate or oblong-ovate, 
upper leaves ovate, acute, semiamplexicaule; flowers sub-

calix acute, about half the length of the corolla tube.

Nearly allied to P. virginica, and also probably to the P. 
niculata, but the leaves are never acuminated or hairy,

are afew scattered hooked, hispid hairs, often only visible 
ina dried state. The name of danceolata is so very imap- 
plicable that it appeared ‘o me necessary to alter it. :
