JDH thanks Otto Stapf for the greetings the latter conveyed on behalf of all the RBG Kew herbarium staff on the occasion of JDH's 90th birthday. He looks back on his time working in the herbarium and library of Kew as 'the happiest of my scientific life' and places great value on the work done by all the dedicated employees, without whom he could not have completed his own labours. He asks that his thanks be past to the staff along with the sentiment that JDH believes in ' he enduring scientific value & the renown of the unique establishment entrusted to their care'.

JDH writes to Otto Stapf regarding the distribution of copies of an article being reprinted. JDH would like to know which institutions receive the reprint, also who received copies of his illustrations of Impatiens from the ICONES [PLANANTARUM]. JDH wants Indo Chinese specimens from Stapf as soon as possible so he can revise his articles on Indian Balsams. JDH is also keen for Miss [Matilda] Smith to complete the drawings of the Balsams for ICONES. Letter has additional notes attached regarding the questions of distribution JDH asks. These notes are written in the hand of Otto Stapf & John Aikman. Known recipients of the Icones illustrations are listed in the notes as Fischer v. Waldheim, Matsumura & Arnoldi as well as 'all those who lent material to Sir Joseph'. The notes also asks about returning copies of Swedish & Danish periodicals which they already have in the RBG Kew library.

JDH returns the New York Herbarium bundle of Impatiens to Otto Stapf. He says that there are 6 species, 1 of which is totally different from the ones in Elmer Merrill's collection. He has completed the diagnoses of the Phillipines species, 20 in total. It was a hard job & only 2 were previously known. The numbering has confused JDH as it is under different headings. There is a table to illustrate this. JDH still has to describe them in detail and then intercalate them with the other Malay examples. He says that all have pedicellate inflorescence & uniform stamens, apart from one. JDH says that Stapf and the Director should take some of the remaining copies of his paper from the ARCHIVES and the ICONES, should they wish. He says a lot of periodicals go with the New York Balsams. He is now to start work on the Indo-Chinese specimens and thanks Stapf for sending part of FLORA GENERALE DE INDO CHINE, and asks if he may keep it until he understands the plants a little more. He says that he will be able to manage with it written in French.

JDH informs Otto Stapf that he is sending a parcel to the Director by rail which contains four items: periodicals; FLORA OF INDO CHINA; SPECIES OF HYDROCERA and ICONES material for Miss [Matilda] Smith. Stapf has annotated the note after JDH's signature, noting that Miss Smith is still ill and that the ICONES material should go to her. He writes 'No more Hydrocera'. He also asks whether anything is known about a journal or diary of Seemann's travels in Oahu beyond what has been published in the LONDON JOURNAL OF BOTANY, and BONPLANDIA.

JDH informs Otto Stapf that he has received a Swedish Journal: ARKIV FÖR BOTANIK number 8 parts 1-5, 1909, issued by Kungl. Svenska Vetenskapsakademien [The Royal Swedish Academy of Sciences]. JDH asks if he should send the work to the herbarium of the Royal Botanic Gardens, Kew. Annotations written in another hand, believed to be that of herbarium assistant Sydney Alfred Skan, indicates that RBG Kew already receives the journal for Stockholm & that it appears in the library catalogue under Stockholm. An additional annotation confirms that the journal is the continuation of an existing one under a different title as JDH suspected: K. VETENSKAPS ACADEMIA. JDH also asks if the RBG Kew library wants L'ACADEMIE INTERNATIONALE DE GEOG. BOT., to which Skan has indicated that they already subscribe.

JDH writes to inform Otto Stapf that he has identified [Alfred Karl] Meebold's supposedly new balsam as an existing species to be found in the RBG Kew herbarium: Impatiens bicolor. He is returning the Balsams addressed to the Director [Sir David Prain]. JDH offers 2 brochures for the RBG Kew herbarium library, they are entitled BOTANISCHE WANDTAFELN & TURGOR DER MARKSTRAHLZELLEN. He does not understand the German terminology in the titles but has determined that they concern the fertilisation of orchids, Beech leaf tissue, a Plasmodium & the treatment of wood by salpeter. They were given to JDH by George King. An annotation signed by Stapf records that he has acknowledged receipt of Meebold's impatiens, accepted the brochures for the library & explained their German titles to JDH.

JDH thanks Otto Stapf for providing him with a list of Balsam names from the card catalogue. He will see to the date of Impatiens lasiophyton. JDH currently working on Meebold's collection, the best organised of any Indian collection he has seen. It includes some new species which JDH will describe for the KEW BULLETIN. JDH recommends a book he is by F.B. Bradley-Birt: THROUGH PERSIA FROM THE GULF TO THE CASPIAN. He praises the descriptions in the book, mentioning particularly the accounts of Shiraz, Sadi [Sari?] & Persepolis. He reports that his eczema has subsided & thanks Stapf for visiting & distracting him whilst he was in pain.
