332 ON WIDDRINGTONTA EQUISETIFORMIS. 
Correction of Widdringtonia equisetiformis to Callitris robusta. 
By Maxwzr, T. MasrEns, M.D., F.R.S., F.L.S. 
Ix the Journal of the Linnean Society, Botany, vol. xxxvii. 
(1905) p. 271, I published a description of what I then considered 
to be a new species of Widdringtonia, under the name of 
W. equisetiformis. I had, on a previous page, noted it as 
exceptional in its characters and as serving to break down the 
distinction between the Australian genus Callitris and the South 
African Widdringtonia. lam indebted to Mr. R. T. Baker, of 
the Technological Museum, Sydney, for pointing out that my 
supposed new species is not a true native of South Africa, but 
that it has been introduced from Australia and is none other 
than Callitris robusta. I believe Mr. Baker is right in his 
suggestion, and in making the necessary correction I am pleased 
to find the distinction between the two genera thus satisfactorily 
confirmed and not invalidated by an interloper.
