to subclaviform, unilocular, with parietal placentae which project inwards and thus form more or 
less imperfect partitions. Seeds 00 , punctate, reniform, without an aril. 
About 40 species ; cosmopolitan.

British species and hybrid of Dubia 
1. P. dubium (see below). Laminae with narrower lobes. Stigmas 4 — 12. Pedicel with 
spreading hairs. Capsules much longer than broad. 
P. dubium x yhoeus (p. 163). Plants with a mixture of, or a blend of the characters of, the putative 
parents. 
2. P. rhoeas (p. 164). Laminae with broader lobes. Pedicel with appressed hairs. Stigmas

Annual. Shoot more or less hairy. Leaves sessile, pinnatipartite, lobes entire or dentate, some- 
what glaucous. Pedicels with appressed hairs. Flowers smaller than in P. rhoeas , about 5^0 or 5 '5 
cm. in diameter; May to July. Petals scarlet, suborbicular. Filaments not inflated, violet. Stigmas 
4 — 12, reaching or nearly reaching the outside edge of the disc. Capsule claviform or subclaviform, 
more or less attenuate below, about 2 0 — 2^5 cm. long and 7 — 8 mm. broad. Disc convex. 
“Linnaeus, by the name dubium , seemed to suspect it might not be distinct from the common poppy, t. 645 [= P. rhoeas\ ; 
but we believe no species can be better defined” (Sir J. E. Smith Eng. Bot. no. 644 (1799)). Our own opinion is that 
P. dubium is very closely allied to P. rhoeas , and that the two species hybridise freely in nature producing several intermediates 
(see P. dubium x rhoeas ) which appear in books as varieties of the one species or the other.
