the upper ones narrow and entire. Flowers numerous in dense, 

 sometimes branched clusters. In cultivated and waste places. An 

 exhausting weed, but furnishing food to stock which compensates 

 to some extent for its aggression. 



Chcnopodium nmbrosioidcs (Stinking goosefoot). Indigenous to 

 America. A weak perrennial shrub, branching from the base, and 

 attaining a height of upwards of four feet ; stems slender, becoming 

 woody when old ; leaves lanceolate - elliptical, emarginate and 

 toothed, smooth, stippled, with numerous minute glandular openings 

 on the underside, the lower between three and four inches long and 

 from one to one and a-half inches wide, the upper gradually 

 diminishing ; flowers small, numerous, in axillary and terminal 

 racemose spikes. The whole plant emits a strong offensive smell, 

 and in consequence is rejected by domesticated animals. 



Chenopodiiiui unirale (Nettle-leaved goosefoot). Indigenous to 

 temperate Europe and Asia. An erect much branched annual 

 reaching a height of over eighteen inches in cultivated lands. Stems 

 redish, robust, succulent ; leaves intensey green, broadly ovate, 

 deeply toothed ; flowers small, abundant, and crowded at the base 

 of the leaves or terminal. A useless and very aggressive weed ; 

 abundant in cultivated lands and waste places. 



Polygonutn aviculare (Wire grass ; crab ; knot-weed ; knot- 

 grass ; iron-weed). Indigenous to Europe, probably originally from 

 Asia. A prostrate much branched weed ; often erect when drawn 

 up by other plants ; stems knotty, wiry, and sometimes upwards of 

 two feet long ; leaves small, narrow, oblong ; flowers whitish, small, 

 and in clusters. This weed is not entirely useless, as stock will eat it, 

 but its feeding qualities are probably not very great, and when old it 

 is not readily digested. 



Riuiic.v acetosclla (Sorrel ; sour dock). Indigenous to Europe. 

 This troublesome weed is, unfortunately, too widely spread not to be 

 known by everyone. The trailing root generally sprouts from the 

 smallest part which makes the eradication of this plant extremely 

 difficult. It has been introduced on many lands with stable manure 

 brought from towns. 



Eniex iuislmUs ( Doublegee ; three-cornered jack ; tanner's 

 curse). Indigenous to South Africa. An erect or trailing suc- 

 culent annual, sometimes developing stems over 18 inches long ; 

 leaves ovate or heart-shaped, rounded at apex, on stems, the 

 lower sometimes over 2 inches long and i [, wide, and including 

 stem 3^ long, the upper diminishingly smaller ; flowers insignificant, 

 situated at the axils of the leaves, the female flowers forming three- 

 cornered spinescent fructifications close to the steins. One of the 

 most aggressive introductions, which during late years has spread 

 to an alarming extent, and seemingly iinds its way to almost every 

 piece of newly-disturbed land in certain districts. Wherever it 

 once gets a start it will rapidly expand and suppress all other
