The genus Hxarrhena was established by Brown in 1810, 
upon a Tasmanian plant, FH. suaveolens, of which he 
describes as ‘a herb with the facies of Myosotis, to which it 
is certainly closely allied, and differs chiefly in the exserted 
stamens and style.” Several species having subsequently 
been discovered in New Zealand, presenting no further 
differences from Myosotis than H. suaveolens did, except in 
that the filaments were very short in some of them, I, in 
the Flora of New Zealand, reduced the genus to Myosotis, 
in which I was followed by Bentham in the “ Flora Aus- 
traliensis” (vol. iv., p. 407). Before the publication of 
the latter work, I had, in the ‘‘ Handbook of the New 
Zealand Flora,” further additions having been made to 
Exarrhena, re-established it, pointing out the additional 
character of its large and more campanulate corolla, 
which however had not satisfied Bentham ; and accordingly 
in the “Genera Plantarum” Hzarrhena is again merged 
in Myosotis. : 
The opportunity of having a living species to examine 
has led me to reinvestigate the matter, and to compare 
ApRit Isr, 1893.
