Sending a copy of [Antonio] Bertoloni's "Amoenitates Italicae". Compared the collection of plants he gathered from Corfu and other islands with Bertoloni's herbarium, the best in Italy, but still has doubts which he can only clear up by consulting [John] Sibthorp's original specimens. [David] Don [(1799-1841), botanist] wants him to communicate his Ionian flora observations to Linnean Society but does not think them interesting enough. The Ionian 'Umbelliferae' are "numerous & extraordinary" and seem little known, could not even apply genera to many of them, although a copy of "Flora Graeca" in the Grand Duke's Library in Florence was helpful.
