22 PLANTS OF MA.ST-HEAD ISLAND. 



equiseti folia. Several of the other species are also widely 

 dispersed, and it is thus evident that this island has been 

 reached by some of the most ubiquitous of plants. 



One of my specimens, StenotapJirum subulatiim, an 

 all}^ of the Buffalo grass, is a new record for Australia. It 

 is a common grass in Xew^ Guinea and Fiji, and will doubt- 

 less before long establish itself on our mainland. A variety 

 allied to this species was secured from the south-eastern 

 Moluccas during the Challenger expedition and may prove 

 to be intermediate between suhulatum and americaiium. 



Leaving on one side the fruit of Castanospermum 

 australe, we have only three Mast- Head species which 

 should be classed as truly endemic to Australia. These ar& 

 Euphorbia eremophila. Ficus opposita and Pandanus pedun- 

 culatus. 



As several Pandani are mentioned from islands in the 

 Pacific but with no specific name attached, the range of 

 this last species ma}^ need to be enlarged. According 

 to Bentham our Abutilon muticum agrees with specimens 

 from tropical Asia, generally referred to A. asiaticum* 



My thanks are due to Mr. F. M. Bailey and his assist- 

 ant, Mr. C. T. White, for help wdth one or two difficult 

 specimens. I should also like to take this opportunity of 

 expressing my obligations to Mr. J. H. Maiden for his ever- 

 ready assistance to botanical workers.
