Scrophularia nodosa & aquatica; in buds & young flowers pistil turns slightly up towards upper petal & in gangway to nectary, where plenty of pollen: at this age anthers not burst— Later pistil bends much down over little lower lip of flower.— From position in which wasps cling when seeking nectar, the pistil would certainly in this position likewise be fertilised.— It was S. aquatica which I saw wasps at Moor Park so eagerly sucking.— The pistil straightens itself after corolla drops off.—
