OVARY OF 



24 papaverAce^ 



magnificent of our native flowers, inhabiting clear pools and slow 

 rivers. The flowers rise above the water in the middle of the day 

 and expand, closing once more and sinking towards evening. — Fl. 

 June — August. Perennial. 



Ord. IV. Papaverace/e. — The Poppy Family 



Herbaceous plants, abounding in a milky narcotic juice. 

 FIotve7-s usually pendulous in the bud, conspicuous and polysym- 

 metric ; sepals 2, soon falling off, concave ; petals 4, crumpled in 

 aestivation ; stamens indefinite, hypogynous ; fruit a 

 capsule ; seeds generally scattered over the surface of 

 incomplete partitions, which radiate from the sides of 

 the capsule, but do not meet at the centre. The 

 narcotic juice of the unripe capsules of Papdver 

 som?iiferum^ the Opium Poppy, which is commonly 

 grown for ornament in our gardens, yields opium, 

 THE POPPY, laudanum, and morphia, most valuable medicines. An 

 infusion of ripe " poppy-heads " or capsules is also used as a 

 fomentation ; and the seeds of all poppies contain a considerable 

 quantity of a mild and wholesome oil.
