This is an annual, native of Spain, and of the South of France, 
a very pretty Plant, flowering in July and Auguft. The Stalk is white, 
Arm, upright, and but little branched ; and grows to two feet high. 
The Leaves are of a pale whitifh green on the upper fide, with fome 
ftiff hairs upon them. They are altogether white underneath, and 
weakly thorny at the Point. The Flowers are of a very pale, but 
very elegant blue ; not unlike the colour we fee in what are called 
Water Sapphires by the Jewellers, in which there feems a milky 
whitenefs fuffus’d among a good blue. 
Herman underftood this Plant to be a Scabious j we fee the utility 
of obferving the feparate Cups, and the propriety of forming a diftinc- 
tion upon their firudture, luperior to Genus, though below a Clafs.
