Figured in Sweet’s Cistacee, Plate 57. 
A creeping, under-ground stem extending to no great distance, 
and throwing out many long, tapering roots, branching with 
thread-like fibrils. The stem rises a few inches from the ground, 
erect or bending downwards, and throwmg out innumerable 
short branches, thickly clothed with a sad, whitish or glaucous 
down, and close set leaves of the same color. Leaves very 
short, lanceolate, pointed, imbricate, and closely embracing the 
stem,—covered with down of a whitish color, through which the 
greener surface indistinctly appears. 
Among these appear in May, yellow flowers, on very short, 
slender stalks, at the ends of the little branches near the extre- 
mity of the stem. The sepals look like the continuation of the 
leaves, being covered with down without, but yellow or reddish 
within. The petals are yellow. Stamens from 9 to 18, with 
roundish anthers. It flowers from May to July. 
In some places near the coast, in Essex County, this plant 
covers the sand, where scarcely any other would vegetate.

This is much less downy than the last, and the slender, awl- 
like leaves, three or four lines long, spread a little, and are cov- 
ered with longer and thinner hairs. It is from six to twelve 
inches high. The old, persistent leaves give the stem a brown 
color. The floweis are like those of the last species, and have 
from 9 to 15 stamens. 
It is found in Martha’s Vineyard and on Nantucket, flowering 
in May and after.
