From Daniel Oliver   8 April 1867

My dear Sir,

Mrs Hooker has put your note into my hands referring to Naegeli & Hieracia. ¹

The difficulty about them is this that hardly anyone has a good set of the peculiar Highland forms excepting M^r James Backhouse Jr of York & the few to whom he has communicated specimens & I doubt if he would undertake to make up a set for Naegeli.²

M^r Baker of the Kew Herbarium has a fair collection of British Hieracia (he has himself published a fasciculus of Teesdale or No. Yorks. species) & he would be glad either to lend Naegeli his collection entire—or to make him up a set of duplicates so far as his stores allow. He has a good set of French critical species but these prob^y. N. has already from Jordan &c.³

Baker thinks neither Babington nor Watson likely to be able to help—at any rate in the way of giving N. a set.⁴

I sh^d. have mentioned that D^r Hooker is at Paris—a Juror⁵

Ever sincerely yrs | Dan^l. Oliver
