During the present Session of the Legislative Assembly it 

 has been proposed to include in the " Xanthium spinosum Law " 

 the closely allied Xanthium strumarium, which, during the last 

 few years has increased in the Colony very considerably, found 

 its way to the upper districts, and appears likely to be as great 

 a pest as X. spinosum. In my Report for 1899 I alluded to this 

 plant, and gave extracts with information as to its alleged 

 poisonous properties, and showing what is thought of it in New 

 South Wales, I am, therefore, pleased to see that it is to be 

 included in the Law, Since it has become known that this was 

 intended I have been applied to by several persons asking 

 whether other noxious weeds could not be included in the same 

 Law, and I therefore give a list of some of those which bear 

 " burrs " more or less injurious to wool, but to include these in 

 the Law would, I fear, be of no real service, but have the effect 

 of making the Law more unworkable than it now is, since 

 farmers are not botanists, and the plants here mentioned have 

 so far as I am aware at present no popular names. I have 

 arranged the Orders to which they belong in botanical sequence, 

 and hope that this list may serve the purpose of calling atten- 

 tion to the subject, so that farmers may do something towards 

 ridding their farms of some of these pests to wool producers. 

 I may add that specimens of wool containing some of these 

 " burrs " have been sent to me by merchants requesting to 

 know what they were, and I think that in each case they were 

 the seedvessels of one of the two species of Gynoglossmn. 



TILIACEAE. 



Triwnfetta effusa (E. Mey). 



A tall herbaceous plant with alternate leaves of very vary- 

 ing shape even on the same plant, usually more or less trilobed, 

 but sometimes the lobes are obsolete, especially on the upper 

 leaves. The larger leaves are 3 to 4 inches long and wide, and 

 are covered on both surfaces with minute simple and stellate 

 hairs, the flowers are yellow, and the capsules about the size of 

 a large pea, and covered with hooked bristles. The whole 

 plant is from 2 to 4 feet high, and flowers during the summer. 

 It is a common weed in the coast districts, but how far it 

 extends inland I am at present unable to say. It has been 

 figured and described in " Natal Plants," and will appear in 

 the next Part issued. 



Triumfetta pilosa, Roth. 



A very similar plant to the last named, but larger in all 

 parts, and reaching to nearly G feet in height, the leaves are 

 either 3-lobed or oblong to lanceolate, 3 to 5 inches long, 1 

 to 3 inches wide, and the whole plant is densely tomentose
