Was it just me or was it a stinker this week? I'm struggling with 5 clues 31a fern genus/north american name for dogs tooth violet 35a figure of speech such as heart of gpld ('twas a cliche in my day but obviously not now). 9d type of musical composition without lyrics (obviously not vocalise or lied ohne worten) 20d kitchen utensil with flat blade used with fried food 45d old name for a horse fly..
