I am indebted to the Director of the Eoyal Gardens, Kew, 

 for the authentication of most of the South American species. 



Note.- — As this paper was written in September, it may be 

 advisable to state that the position of several of the surviving 

 species has somewhat improved during the iaterval. Aster 

 ivihricatus has increased to a considerable extent, and Cheno- 

 podium ambrosioides is more plentiful. Boubieva multifida 

 must have produced perfect seeds, as it has increased con- 

 siderably, although I failed to detect them ; several plants of 

 Petunia parviflora have made their appearance ; and there are 

 about a score specimens of Chenopodium ficifolium ; while the 

 old plants of Pascalia glauca have developed new stems, which 

 seem likely to produce flowers in April. 



It will be remembered that the ballast was used in the 

 formation of a platform at the passenger-station. The sur- 

 face of the platform has been covered with asphalt ; but 

 beyond the asphalted portion I found three specmiens of 

 Pascalia, and in the immediate vicinity several plants of 

 Boubieva and Chenopodium ficifolium. Should the platform 

 be broken up during the twentieth century, most of the plants 

 enumerated in the list will doubtless make their appearance 

 in profusion.
