with a mass of foreign vegetation, thus giving it a unique 

 appearance. 



Two introduced members of the Cruciferae found growing 

 there are worthy of mention — Brassica campestris, L., the Rape 

 or Wild Turnip, and Diplotaxis tennijolia, D. C, Sand Mustard 

 or Rocket. The latter is a native of Europe. This w^as the 

 second locality recorded in this State for the Sand Mustard. 

 Some of the roots of D. tenuijolia were found to have penetrated 

 the loose ballast to a depth of at least three feet. 



Among the Compositae may be mentioned Ursinia chrys- 

 anthemoides, Harv., a native of South Africa, which is only 

 known in this State from this locality. It was growing in 

 great profusion, and when seen from a distance whilst in 

 flower it reminded one of a field covered with Cape-weed, 

 Cryptostemma calendulacemn. It has somewhat the habit and 

 appearance of some of the chrysanthemums, and hence arises 

 the specific name. I brought away some of the young plants 

 of the Ursinia, and planted them in my garden ; but they 

 seeded so freely and spread so rapidly that I had to pull them 

 up, or they would have taken possession of the garden. 



Another immigrant from South Africa, Dimorphotheca 

 plnvialis, Moench., like the preceding one known only from 

 Coode Island, was fairly plentiful, as was likewise Matricaria 

 globifera, Fenzl., the Globe Chamomile. This South African 

 composite has since been found near Geelong, and is there- 

 fore apparently establishing itself as a naturalized alien around 

 Port Phillip. Another South African plant, Bcrkheya [Stohcea) 

 i^igida, Thunb., African Thistle, noted from this locality, like 

 the preceding one, has since been received from Geelong 

 district, and is now classed as a naturalized alien in this State 

 (see " Weeds, Poison Plants, and Naturalized Aliens of Vic- 

 toria," page 73). Two other composites — Matricaria inodora, 

 L., Scentless Chamomile, and Senecio nehrodensis, L., var. 

 glabrattis, D. C, natives of Europe and Asia — were also noted for 

 the first time in Victoria. 



Three members of the Ficoidese indigenous to South Africa 

 were noted — Tetragona fruticosa, L., Tetragona decumhens. 

 Mill., and Mesemhryanthcmmn angidatum, Thunb. These 

 covered the ground in a thick mass, the branching stems 

 trailing out in all directions. A member of the Zygophyllea; 

 endemic to South Africa was Zygophyllum sessifolimn, L. This 

 plant, with its yellow flowers, looked rather pretty, and I took 

 some of the young plants to grow them in my garden ; but, 

 like the Ursinia, I had to pull it up, for it soon began to spread 

 all over the garden, and, as it seeded freely, it would probably 

 have eventually spread outside if unchecked.
