Presentlÿ I have under observation a verÿ remarkable calyptra-like way of opening of the flower of Papaver hybridum (2 pots with 50–60 specimens); all of them cleistogamous, and verÿ fertile; by the bÿ somewhat dwarfish (from standing on too narrow ground). The case has some resemblance with Vitis vinifera.—¹ Not recorded in Masters’ teratologÿ.² Quite new to me, and very different from the ordinarÿ behaviour of this plant in previous generations and even now (of her sisters) under ordinary circumstances (in open ground).
