Golden Wave or Lance-Leaved Tickseed

I uploaded pictures of Marguerite about a month ago. After that this flower began to open. The name is Golden Wave ('Oo-Kinkeigiku') or Lance-Leaved Tickseed ('Kinkeigiku'). I cannot distinguish these two...





At first I thought this is yellow Marguerite (^_^;;;
Oh, the botanical name is Coreopsis Drummondii or Coreopsis Lanceolata!
