AT firft fight this little plant, in its larger ftate, forms fome refemblance to the Shepherds Purje ; and 

 when fmall, may be overlooked or miftaken for the Br aba verna, particularly as it grows in fimilar fituations ; 

 but by its ilender pods it may readily be diflinguifhed. _ j ^ 



We have it frequent enough on our walls, and fometimes on dry ground, about town : and it may be found 

 in great abundance on the fouth 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 Cicutartum. 



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 ^ot 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. p . 



The Glandula Ne5iarifer<z, often found at the bafe of the Stamina, in the plants of the Clafs Tetradynamia, 

 and which according to Linnjeus form the character of the Genus Arabis, are in this fpecies fo very minute, 

 as fcarcely to be difcerned with a magnifier
