CRUCIFEROUS PLANTS. 101 
The native Poppy (Papaver aculeatum) is an annual plant 
with milky sap ; the leaves are pinnatifid-jagged, as well as the 
stem flowerstalks and sepals armed with short rigid spreading 
bristlets ; lobes of the leaves short, comparatively broad, acutely 
toothed; flowerbuds drooping; sepals two or seldom three, 
deciduous ; petals scarlet or brick-colored, about twice as long 
as the brown-yellow numerous upwards capillary filaments, 
usually four or sometimes 
Six, comparatively small, 
very fugacious ; anthers 
heartshaped-oval, yellow- 
ish, their dehiscence mar- 
ginal ; teeth of the radiate- 
stigmatiferous disk 5-9, 
minute, | semi - orbicular ; 
margin of the disk slightly 
waved, not folded; fruit 
glabrous, truncate-ellipsoid, 
opening under the disk ; 
placentas extending from 
the walls of the fruit scarcely 
half way towards the centre ~ 
of the cavity ; seeds brown- 
ish-black. This species 
seems confined to the sandy 
desert-country towards the 
Murray-River, so far as our 
colony is concerned ; it oc- 
curs however also in the 
surrounding colonies, and 
may possibly have come first 
to us from South-Africa. 
The Opium - Poppy (Pa- 
paver somniferum) of the 
countries around the Medi- 
terranean Sea, an inmate of 
many of our gardens, affords 
Fig XLVIILa.
