and sessile, of — densely-placed, purple flowers. Calyx 
greenish, white and scariose, hairy, five-toothed, two short 
teeth on each side, and the lowermost as long as the tube 
of the corolla, all setaceous and purple. Petals conjoined. 
Vexillum cylindrical for a great part of its length, spread- 
ing upwards, and but little longer than the ale and carina. 
A most elaborate history of this species of Clover or Tre- 
foil is given by Professor Arzexius, in the first volume of 
the Transactions of the Linnean Society of London. It is 
a native of subalpine countries, in various, especially the 
southern parts of the continent of Europe, and was culti- 
vated, according to the Hortus Kewensis, in the Gardens of 
Britain before 1789. It is perfectly hardy, and is a very 
desirable plant ; its heads of flowers being of a peculiarly 
rich and bright purple. With us, in the Glasgow Botanic 
Garden, it flowers in the month of June.
