Claytoma PBRt'OLIATA, Don. " Perfoliate (Jlaytoiiia." (Portulaeeae). 



Baulkamaugh, near Sheppartori, W. H. Callister, October, 1915; 

 Smythesdale, Mabel White, October, 1915. 



It is a native of Ninth America, naturalised as a weed in Europe, 

 raid now apparently in process of establishing itself as a naturalised 

 alien in Victoria. It has no poisonous or injurious properties, and 

 in pasture it will do no harm, as it is oaten by stock, and has also» 

 been used as a salad vegetable or spinach. In cultivated land or in 

 gardens it would be troublesome, owing to its rapid powers of seed- 

 ing. The plant can hardly be regarded as definitely "naturalised as- 

 yet, and. may not be permanently established in the Shepparton 

 locality, as it was found by a farmer growing near a boot scraper 

 at his kitchen door, apparently from seeds picked up on the boots 

 when walking through the fields, but no other plants could be found 

 growing in the open fields. They might, however, have died down 

 after seeding, and may reappear later on. 



Homekia collina, Benth, var mimata, Sweet. Cape Tulip. 

 (Irideae). 



This poisonous weed, a native of S. Africa, has in the past 1(> 

 years spread at Carisbrook, until it now cover? about 500 acres, a 

 few fields containing more of it than of any other plant. The bulbils 

 produced above and below ground make the plant very hard to sup- 

 press when once established. Thorough cultivation and leafy crops 

 gradually suppress it. Where the ground is not broken frequent 

 cutting is necessary. If dug out and the ground left bare, it soon 

 reappears in greater abundance than before, owing to the small 

 bulbils and seeds left behind in the soil. 



Orthocarpus pdrpukascbks, Benth. Purple Orthocarpus. (Scro- 

 phulariaceae). 



Euroa, J. G. Saunderson, November, 1915. 



This plant, a native of California, is injurious in pastures oit 

 account of its roots being parasitic on the roots of grasses. It is a 

 freely seeding annual, introduced with fodder imported from N. 

 America, but not sufficiently established to be considered naturalised. 

 It is not poisonous, bub suddenly appeared in many localities in 1915.. 



Species of Pterostylis. 



Much confusion has existed in the determination of many of the 

 species of this group.
