 claw dull yellow, veined with purple; inner segms. 

 erect, nearly straight. May. Cent, and S. Eu. B.M.

 near the base. Used as a forage plant. Does well 

 in driest situations. Gt. 47:1452. Described by 

 Wittmack, Gt. 47, p. 369. The seeds should be sown 

 in beds, and the young plants set out the following 

 spring, 10 in. apart each way, where they are to 

 remain.
