cilpinum grown in gardens. P. Rhceas is normally of a vivid scarlet, 
often with rich black spots or markings internally at the base of 
the petals, sometimes very pronounced, whilst plants may frequently 
he found bearing paler red flowers almost similar to those of dubium 
rarely, the petals are of a “ crushed strawberry ” tint or of a purplish 
hue, recalling Rcemeria hybrida. In short, the colour is distinctly 
variable. 
On the other hand, the flowers of P. dubium seem to be much 
more constant in colour and I could not find blossoms either with 
black spots at the base or of the vivid scarlet of Rhceas. 
To sum up, the general effect of a flower of typical Rhceas is a 
bright scarlet blossom with a dark centre, whilst that of dubium is 
a more pallid flower with a paler centre. 
It may here be noted that all our “red” poppies are thus 
really distinct in tint, the flowers of P. Argemone being small, pale- 
red with a black base to the petals, whilst those of P. hybridum are 
distinctly purplish, as already noted by Mr. H. S. Thompson (fourn. 
Bot., 1913, 172), who may, I think, rest assured that our British 
form does not differ in tint from the Continental plant. 
Buds. In P. Rhceas these are coarsely and roughly tuber- 
culately-hairy, irregular in shape, obvoid, blunt at the apex, broadest 
above the middle (rarely at the middle) (Fig. 3); in dubium the buds 
are less roughly-tubercular with whiter and more silky hairs, they 
are more symmetrical and graceful in shape, ovoid, tapering to a 
more acute apex and are broadest below the middle (Fig. 2). 
Hairs on peduncles. These, in typical Rhceas, appear to be + 
numerous, irregularly horizontally-patent and yellowish in colour 
(red in the form Pryorii) ; in dubium they are copious and appressed, 
more regular in character, white and more abundant than in Rhceas. 
Summit of peduncles. The dilated summit, in P. Rhceas, is 
broader than the base of the capsule and its pronounced carpophore ; 
in dubium, the enlarged summit is slightly narrower than the base 
of capsule, which has a shorter carpophore. 
Anthers and Pollen. The anthers of P. Rhceas are distinctly 
dark, greenish-or-violet tinted, often nearly black; the pollen, 
greenish-yellow. In dubium the anthers are not so dark in tint, of 
a slaty-green colour and their pollen is a clear yellow. 
Stigma disc. Whilst the plant is in flower the rays of the disc in P.Rhceas 
are dark in colour, often purplish (rarely yellow), whilst those of dubium 
during a corresponding period are invariably yellow and I could not 
’ These may be of hybrid origin.
