ROOT annual, Ample, fibrous, whitifh. 
LEAVES of an oblong oval fhape, Handing onfoot-ftalks, 
indented, efpecially near the bafe of the leaf, 
hairy, rough on each fide, with little promi- 
nent points ; leaves on the {talk feflile and 
indented, fig. 1 2 ; the hairs at the bafe of 
the leaf Ample, thofe at the edges and on the 
furface dividing into two or three forks. 
STALK from fix to twelve inches high, upright, fome- 
what branched, round,- crooked, covered with 
a bloom, hairy, the little branches alternate 
and drooping. 
CALYX : a Perianthium of four leaves, which are 
oval, concave, and flightly hairy, jig. 3, mag.

Calyx, dilated at top, entire and obtufe, jig. 4. 
STAMINA : four tapering Filaments, two of which 
are fliorter than the others, Jig. 5 ; Anthers 
fmall and yellow. 
PISTILLUM: Germen oblong, {lender. Style very 
fhort, equal in height to the Stamina; Stigma 
blunt, jig. 6. 
SEED-VESSEL : a fmall {lender pod about half an 
inch long, of two valves, jig. 7, 8, containing 
SEEDS. Several yellowifh feeds, jig. 9. 
AT firft fight this little plant, in its larger Hate, forms fome refemblance to the Shepherds Purfe ; and 
when fmall, may be overlooked or miflaken for the Draba verna, particularly as it grows in fimilar filiations - 
but by its {lender pods it may readily be diftinguifhed. 
We have it frequent enough on our walls, and fometimes on dry ground, about town: and it may be found 
in great abundance on thefouth fide of Greenwich Park Wall, the top of which, facing the late Sir Gregory Page’s 
is in particular parts almoft covered with it ; while the bottom of it, is at the fame time, beautifully orna- 
mented with the Geranium Cicutarium. ’ J 
It flowers in March and April, and the feed is ripe in May. 
No particular virtues or ufes are afcribed to it. 
Like all other plants (which is a circumftance that cannot be too often inculcated into the mind of the 
young Botanift) it varies very much in fize; fometimes being not more than an inch or two in height and 
at other times more than a foot. 6 * 
The Glandula NeStarfera , often found at the bafe of the Stamina, in the plants of the Clafs Petr adynamia 
and which according to Linnjeus form the charadler of the Genus Arabis, are in this fpecies fo very minute’ 
as'fcarcely to be difcerned with a magnifier J *
