Van Dieman’s Land. Mr Gunn. (n. 547.) 
Mr Gunn’s specimens are smaller and less hairy than those 
figured in Richard’s Monograph, but they vary in size. The 
two lateral ridges on the carpels are united into one; between 
them and the commissure there is, on each side, a small deep 
sunken pit or hollow, which gives to a transverse section of a 
carpel a remarkably contracted appearance towards the com- 
missure. This curious feature is not represented in Richard’s 
work; the specimens there described, probably, not exhibiting 
perfectly ripe fruit. J. D. H.
