Papaver.] IV, PAPAVERACEA, 19 
In waste and cultivated places in central and southern Europe to the 
Caucasus, disappearing in northern Germany. In Britain rather rare, 
chiefly in sandy and chalky fields in England and Ireland. 1. summer. 
5. P. Argemone, Linn. (fig. 40). Pale P.—The weakest, and often 
the smallest of our red Poppies, the segments of the leaves few and 
narrow, the flowers rather small, of a pale red, often with a dark spot. 
Filaments of the stamens dilated as in P. hybridum. Capsule oblong, 
contracted at the base, bearing, especially towards the top, a few stiff 
hairs or bristles, more erect from the base than in P. hybridum. 
Stations and geographical range about the same as those of P. Rheas, 
but much less common in Britain and central Hurope. Fl. swmmer. 
Il. MECONOPSIS. MECONOPSIS. 
Ovary ovoid, with a short but distinct style, and a slightly dilated 
stigma of 4 to 6 rays. Capsule opening at the top in as many short 
valves, the placentas inside lining the cavity, but not projecting to the 
centre. 
A small genus, containing, besides the European species, a few others 
from central Asia and north-western America. 
1, M. cambrica, Vig. (fig. 41). Welsh P. —Stock perennial, form- 
ing, when old, large tufts with thick, tapering roots. Stems erect, 
about a foot high. Leaves on long stalks, pale green and slightly 
hairy, pinnate, the segments distinct or slightly decurrent along the 
leafstalk, ovate or lanceolate, toothed or pinnately lobed. Flowers 
rather large, pale yellow, on long peduncles. Capsules narrow, ovate, 
or oblong, glabrous. | 
In rocky woods and shady places, in the hilly districts of western 
Europe, from Spain to Ireland, Wales, and the western counties of 
England. fl. summer. 
II]. CHELIDONIUM. CHLANDINE. 
Ovary linear, ending in a short style, with a small, slightly 2-lobed 
stigma. Capsule long, linear, opening from the base upwards, in two 
valves, the placentas slender. Seeds with a small crest-like appendage 
next the hilum. 
A genus now reduced to a single species. 
1, C. majus, Linn. (fig. 42). Common Celandine.—Rootstock peren- 
nial. Stems erect, slender, branching, 1 to 2 feet high, full of a yellow 
fetid juice, and generally bearing a few spreading hairs. Leaves thin, 
glaucous underneath, once or twice pinnate, the segments ovate, 
coarsely toothed or lobed, the stalks often dilated into a kind of false 
stipules. Flowers smalland yellow, 3 to 6 together, in a loose umbel, on 
along peduncle. Pod nearly cylindrical, glabrous, 1§ to 2 inches long. 
On roadsides and waste places, throughout Europe and Russian Asia 
except the extreme north. In Britain, chiefly near houses. Frequeni 
in England and some parts of Ireland, less so in Scotland. FY. all 
summer. 
IV. ROMERIA. RGIMERIA. 
Ovary linear, with a sessile stigma of 3 or 4 short rays. Capsule long 
and linear, opening from the summit downwards in 8 or 4 valves, the 
placentas slender. Seeds without any crest-like appendage.
