10 THE FLORA OF NORFOLK ISLAND, 



ASCLEPIADE^:. 



69. Tylophora biglandulosa, A. Gray, Proc. Am. Acad. Sc, 

 V. 1864 ; F.v.M, Fragm. ix. 169. (Syn. llybanthera higlandiL- 

 losa, EndL, Prod. Norf. 115). 



T. enervia, F.v.M. The species hitherto only recorded from 

 Lord Howe Island, but found by me in Norfolk Island also. 

 There is great variation in the width of the leaves of this plant. 

 I consulted Mr. Rudolph Schlechter, an authority on the 

 Asclepiadece, who was recently in Sydne}^, and he is of opinion 

 that the species is probably not difierent from 2\ biglanchdosa. 

 I could find only one species on the Island, and therefore recom- 

 mend that T. enervia be not recognised as a separate species 

 pending further enquiry.
