of which the pètals are nearly obsolete, and Virginica, for the most part with a naked unbranched stalk,
furnished below with a great foliaceous bract, sometimes with a short secondary branch proceeding from it.”

specimens of an Tris, of which I will not venture to draw up a character from the dried specimens ;
but which will doubtless be a subject of remark in the Monograph oflrideee, preparing for the press by that
zealous botanist. The note made by Mr Herbert, is to the following effect : “ Iris Caurina, W. H., caule
simplici vel ramulo inferiore minore breviore and further, “ this plant has certainly the aspect of I
tridentata, but its petals are perfect, and the main distinction between its flower and that of Virginica is
thereby removed, the tridentate petal being only an imperfection. The sub-equal fork characterizes I
Virginica."

“ Afler m“nths nnd months,” says Dr Boott, " of intermittent study of Carer, I have completed the list
of British and North American species, for publication in your British North American Flora, and if the
deepest interest in the subject avails much, I can offer that as a recommendation of my humble labours. I
have made the sketch as concise as possible, and, therefore, 1 hope you will publish it as I send it, letting me
bear the responsibility of its defects. In a genus comprising so many speeies, I have thought it advisable at
once to annex a fall deacription of the new speoies. It will give an additional value to your admirable work ;
and, to afford space, I have inserted nothing on the known species, but what is essential to their bein- recognised,
leaving synonyms to be gleaned generally from works that are easy of access to all. I have re-
