yellow. Pedicels rather long, slender, hoary. Calyx of 
four, equal, ovate, concave leaflets. Corolla of four, obo- 
vato-oblong, slightly clawed, veiny petals, twice the length 
of the calyx. Stamens yellow: Anther ovate: Pistil : 
Germen elliptical, stellato-pubescent, tipped with a colum- 
nar style, scarcely its own length. Stigma capitate, mi- 
nutely glandular. Pouch nearly globular, slightly com- , 
pressed at the dissepiment, inflated, sparingly clothed with 
stellated pubescence: tipped with the persistent style and 
stigma. Seeds, six in each cell, brown, orbicular and com- 
pressed. Dissepiment very thin and membranaceous, pure 
white. Embryo green, with the radicle applied to the 
edges of the Cotyledons. 
This species of Vestcaria was first discovered by. Profes- 
sor GiEsEKE, at Omenak in Greenland, and figured in the 
Flora Danica as Atyssum arcticum. Dr. Ricuarpson de- 
tected it in Arctic America, in lat. 67°, and gave an excel- 
lent description of it in the Appendix to Capt. Franxuin’s 
Journal ; rightly referring it to the genus Vesicaria. Again, 
Mr. Drummonp, during Capt. Franxuin’s second Journey, 
found it abundantly upon the Rocky Mountains. 
From seeds, gathered by Mr. Drummonp, and presented, 
together with many others by Captain Franxun and Dr. 
Ricnarpson to the Glasgow Botanic Garden, plants were 
raised, which blossomed during the same year in which they 
were sown, in the months of August and September. The 
flowers are of a bright and vivid yellow, and appear in suc- 
cession for a considerable length of time; so that it is a 
most desirable plant for rock-work. :
