Papaver. | IV. PAPAVERACER. 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 Poppy.—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, con- 
tracted 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. Rhaas, 
but much ess common in Britain and Central Europe. 7. summer. 
II. 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 Poppy.—Stock perennial, 
forming, 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. 
Ill. CHELIDONIUM. CELANDINE. 
Ovary linear, ending in ashort style, with a small, slightly 2-lobed stigma 
Capsule long and linear, opening from the base upwards, in two valves, the 
placentas inconspicuous, 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 small and yellow, 3 to 6 together, in a loose umbel, on a long 
peduncle. Pod nearly cylindrical, glabrous, 13 to 2 inches long. 
On roadsides and waste places, throughout Europe and Russian Asia 
except the extreme north. In Britain, chiefly near houses. Frequent in 
England and some parts of Ireland, less so in Scotland. £7. all summer. 
IV. RHMERIA. REMERIA. 
Ovary linear, with a sessile stigma of 3 or 4 short rays, Capsule long 
and linear, opening from the summit downwards in 3 or 4 valves, the 
placentas inconspicuous, Seeds without any crest-like appendage.
