From Hermann Hoffmann   4 July 1877

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).

Yours v. f. | H. H

Giessen. 4. Julÿ 77
