Yellow-juiced Poppy - Papaver lecoqii

Alternative names
Papaver dubium ssp. lecoqii

Visually identical to Long-headed Poppy (Paper dubium) and was treated as a subspecies (Papaver dubium ssp. Lecoqii) until the publication of new names and taxa in the third edition of Stace which changed it to Papaver lecoqii. The test for Papaver lecoqii is to break and squeeze the stem so that the juice becomes visible. In Papaver lecoqii this is quite a bright yellow, although it may need 30 second or so to become obvious - (the juice is white in Papaver dubium).
