JDH explains he has not written to Asa Gray recently because he is particularly busy during the absence of his aide, William Turner Thiselton-Dyer, who is at South Kensington. JDH is working on a botanical primer for the Macmillan series & doing experiments for himself & Charles Darwin on insectivorous or carnivorous plants: Cephalotes, Nepenthes & Sarracenia. Has neglected work on GENERA PLANTARUM. Has had difficulty getting good systematic contributions for the FLORA INDICA, Thiselton-Dyer & Hiern did good work but Edgeworth, Masters, Andrews & Lawson all needed a lot of correction. Tells Gray about his trip to Florence, Italy for a Congress, run badly by Filippo Parlatore who JDH calls a Tragopogon [also known as 'goatsbeard'] & a 'little toad'. During the trip he saw the Miss Horners, Bakle & his wife, & Mrs Harvey. He also went to Paris, Nimes, Montpelier, Antibes, Hanbury's brother's place near Montara, Genoa, Spezzie [La Spezia] & Pisa & returned via Venice, the Brenner [Pass] Munich & Paris.
