14 FUMARIACEH.—ZYGOPHYLLEE. 
Our introduced weeds include five poppies, all annuals, of which the 
first two, though fairly common, are not yet dangerously abundant, and the 
last three are still comparatively rare. : 
Papaver hybridum, L. The Wild, or Rough-headed Poppy. A native 
of Europe, Asia, and North Africa. It has large flowers with a black 
Spot at the base of each petal, and a rounded bristly capsule. _ ; 
P. Rheas, L. The Common Red, or Field Poppy. A native of 
Europe, Asia, and North Africa. It has a smooth rounded capsule. 
Glaucium flavum, Crantz. (Glaucium luteum, Scop.) A native »f 
Europe, usually found near the seashore. It is the Sea, or- Horned 
Poppy, and has yellow flowers and a long pod. 
Argemone mexicana, L. The Prickly Poppy. It is a native of 
America, with spiny leaves and a five partite capsule. 
A. ochroleuca, Sweet. The Yellow Poppy. It is a native of Mexico. 
The Prickly Poppy has spread as a weed over nearly all the warmer 
regions of the globe. 
i= All these plants have feeble medicinal or poisonous properties, but 
none of them have any pronounced economic value. The taste is usually 
sufficient to keep well-fed stock from them. None of the introduced 
poppies can as yet be classed as really serious weeds. 
FuMARIACEZ (FuMitTory FamIty). 
A small family, differing from the Poppies in the irregular flowers, and 
six instead of numerous stamens. 
Fumaria officinalis, L. The Common Fumitory. This is a small 
annual with much divided leaves, the segments of which can grasp sup- 
ports. It has pale pink racemes of flowers. Although found in many 
parts of Victoria, this cosmopolitan weed is easily kept under. It is not 
poisonous, has no appreciable economic value, and does not appear likely 
to become permanently troublesome, except in gardens. The seed appear 
able to lie dormant in the soil for a few years, coming up when the ground 
is broken up and seeded down, and often giving rise to complaints that a 
seedsman has sold seed of this plant instead of grass or clover seed. 
ZYGOPHYLLEZ (BEAN CapER FAMILY). 
Zygophyllum itodocarpum, F.v.M. A native of Australia; is often 
accused of being poisonous to stock, but the evidence is insufficient, and 
usually they do not touch it. 
CrucirERz (CaBBacE F amity). 
This is a very homogenous order as regards floral characteristics, all 
the flowers being of the Wallflower type, and white or yellow, very rarely 
pink to reddish-brown. Four sepals, four petals, six stamens, four long and 
two short. Ovary superior, forming a short or long pod. 
All have a volatile pungent principle, which is especially well developed 
‘in the horse radish and mustard, and much less abundant in rape, cab- 
‘bage, and turnip. The order includes both annuals and perennials, the 
latter being sometimes almost shrubby in character. A large number of 
‘weeds, some of them very troublesome, belong to the order, but none can 
‘be classed as poisonous, though some, like mustard and horse radish, and 
‘sometimes the common radish, act as emetics when eaten in excess. 
Brassica sinapistrum, Bois. (Sinapis arvensis, L.). Charlock or Wild 
Mustard. A native of Europe. A coarse annual, one to two feet high, 
with a few stiff spreading hairs. Leaves rough, with very short hairs, the 
ower ones usually with one large oval or oblong coarsely-toothed segment, 
and a few smaller ones along the leafstalk. The upper ones often un-
