CD’s observations on curved styles read well. JDH seeks morphological rationale of curvature in the position of nectaries.
He has avoided lecturing to Royal Family’s children at Buckingham Palace.
Has examined Leschenaultia and concludes the external viscid surfaces have nothing to do with the stigmatic surface. Agrees with CD’s style and nectary conclusions; accounts for their form and position in irregular flowers by describing floral development.
[Enclosed are some queries by CD with answers by JDH. Gives information on seed setting by Mucuna
and an opinion on the abruptness of N. and S. limits of plant ranges.]
Glad to hear good news of Etty [Henrietta Darwin].
CD’s observations on Scaevola are capital. The indusium collects the pollen and is the homologue of the pollen-collecting hairs of Campanula. A boat-shaped organ forms a second indusium, the inside base of which forms the stigmatic surface. The latter later protrudes as horns, forming the stigma.
Describes W. H. Harvey’s scientific career and thinks his letter interesting. Agrees with Harvey that the primary agency of natural selection is as great a mystery as ever. [Response to 2823.]
JDH reports on the debate on the Origin at Oxford [BAAS] meeting.
Encourages CD’s work in vegetable physiology.
Ascending the Lebanon JDH noted limits of plant distribution as CD requested: lower limits of a genus sharper than upper. Sharpness of boundaries related to a plant’s moisture requirement.
Impressed by "sporadic" distribution at the Jardin des Plantes in Paris.
JDH’s page-by-page criticisms on Origin, first edition, as requested by CD for preparation of the third edition.
CD’s article worth publishing in Gardeners’ Chronicle. JDH interprets CD’s observation in terms of selection. Has observed similar phenomenon in Cruciferae, where it can be taxonomically important.
CD’s divergent series explains those anomalous plants that hover between what would otherwise be two species in a genus.
Inclined to see conifers as a sub-series of dicotyledons that developed in parallel to monocotyledons, but retained cryptogamic characters.
Mentions H. C. Watson’s view of variations.
Man has destroyed more species than he has created varieties.
Variations are centrifugal because the chances are a million to one that identity of form once lost will return.
In the human race, we find no reversion "that would lead us to confound a man with his ancestors".

A two page typescript letter to Dr Thomas Anderson
A short letter to Thomas Anderson from Joseph Hooker.
Two paragraph letter to Thomas Anderson.
JDH informs Asa Gray that he thinks Picrasma japonica is the same as P. ailanthoides. He is not convinced that Gray's Amaroria is a valid genus, it is close to Soulamea. JDH has seen Monroe. Asks Gray not to send things via bookseller as it is expensive, Trupena's charges are especially high. Mentions Gray's description of Holacantha, & correct use of the term hypogynous. Work on the Arctic flora has led JDH to consider the correct classification of North temperate flora, for example Alsineae; many of which could be referred to Stellarias, Holostea or Gramineae. Speculates that Greenland flora is unique & limited due to glacial factors. JDH can find no specimen of Dupontia cooleyi [at the RBG Kew herbarium]. He asks how Narthecium americanum differs from N. ossifragum. JDH has a newborn son [Brian Harvey Hodgson Hooker]. [George] Bentham is continuing the Hong Kong colonial flora, FLORA HONKONGENSIS, with support from the Treasury. JDH gives his opinion on [Richard] Owen's review of [Charles] Darwin's theory of evolution [ON THE ORIGIN OF SPECIES BY MEANS OF NATURAL SELECTION]. Mentions reviews of his own essay [on plant distribution in the FLORA ANTARCTICA, supporting Darwin's theory]. Gray owes JDH for Horsfield's plants. JDH bought Booth's Bhutan plants at the [Thomas] Nuttall [estate] sale. [Letter incomplete, it bears no valediction or signature but is written in the hand of Sir Joseph Dalton Hooker].

An undated letter from Joseph Hooker to Miles Berkeley.

Short letter from Joseph Hooker to Miles Berkeley identifying a Lonicera as L.involuncrata Banks of California. Mentions that William Hookers is in Torquay and Maria Hooker is in Norfolk.
