of the blossom very long. There is something so singular in this plant, 
that its economy merits further inquiry. The strong horny stellated sub¬ 
stance which grows from the extremity of the fruit-stalk, stretching its 
rays outwards and downwards, incloses and presses the capsules to the 
ground, thus partially burying them. (Mr. G. E. Smith observes, that 
its seedlings are distinguished in winter by the varied pale and dark 
spotted pattern upon their leaves; and that upon the sandy ground 
belo w Folkstone church, this plant, with its singular stellated floral- 
radicles, may be studied to advantage. E.)
