Non-endemic Ascension Island plants brought by man, not wind-transported.
Bentham has found intermediates between oxlip and cowslip in Herefordshire.
JDH finds quantity of albumen in seeds is not variable within a species.
My dear Darwin
Nymphæa seeds—we can get you plenty in Autumn if you will remind me.
Ascenscion plants. I found only 3 or 4 native phænogams,
& as many Ferns— I was wrong about the Rubiaceous genus &
should have said Hedyotis (a very common trop. genus)— the plants are
Aristida do. (grass.
& perhaps one or two Cyperaceæ
The Ferns are generally not St
Had the winds transported seeds at all there ought to be many common trop. weeds on the Mt. top—but I believe that every non endemic flowering plant of Ascenscion has been imported by man— all may be traced to the garden & houses, as far as I could detect.
Scabiosa & Cnestis—the observations no doubt refer to species and not to individuals. I should rebut that the amount of albumen (perisperm) would be constant in the individuals of the species,—at least in some other exalbuminous orders in some few species of which I have found a little albumen (Compositæ & Halorageæ) I do not find the quantity variable
Bentham did not cultivate the Dandelions (to which his observations refer) he watched the effects of light, shade, seasons &c on the forms (species of Dl.) growing about him at Montpellier.
Seed of Glyceria fluitans is abundantly collected (from the wild plants) & eaten in Holland & Russia & exported also, being the true“Manna Croup”.— Zizania was & is eaten abundantly by N. Am Indians, but is not cult.
Dréges Verseidinity is not a mere catalogue, but elaborate table of
distributions hideously closely printed, & diabolically
complicated— I doubt if you can get it in the
Linnean, but I will lend you the Kew copy for a fortnight or
month if you would care for it
Oxlip—Caucasus to lat of Moscow.—
Cowslip—Caucasus to lat. of St Petersbugh,
(Compare English distribution)
Forbes map sent to Royal Society.
Lyallia Kerguelensis— I have lost clue to the American affinity—probably a myth.
In Herefordshire where both Oxlips & Cowslips grow, Bentham finds plenty of intermediates
Bentham would not have altered his Targioni review for ADCs book —but I think that ADC. would for Bentham's review—
Will you let me know when you have spoken to Lord Overton
about Huxley & Athenæum & I will
back it up through Lord Os
- f1 1869.f1CD had apparently sent Hooker a list of questions relating to their discussions during Hooker's visit to Down House from 22 to 28 April (Emma Darwin's diary). The Nymphaea seeds were for CD's seed-soaking experiments (Experimental book, p. 14 (DAR 157a)).
- f2 1869.f2Hooker had visited Ascension Island and St Helena in 1843 during the voyage of H.M.S. Erebus (L. Huxley ed. 1918, 1: 53). He had first mentioned the dissimilarity in their floras, despite their proximity, in Correspondence vol. 3, letter from J. D. Hooker, 29 November 1844.
- f3 1869.f3The amount of albumen in seeds was thought by Hooker to be related to their ability to survive immersion in sea-water. He had earlier suggested that CD test the germination of albuminous seeds after immersion in sea-water (Correspondence vol. 5, letter to J. D. Hooker, 19 April ).
- f4 1869.f4The observations have not been found. George Bentham had lived in Montpellier from 1816 to 1826 (DNB).
- f5 1869.f5‘Manna-croup’ is the name given both to the coarse residue from grinding flour and to a similar meal made from the seeds of the manna-grass, Glyceria fluitans [hence the true manna-croup] (OED).
- f6 1869.f6Zizania aquatica, so-called wild rice, was once a staple food of North American Indians.
- f7 1869.f7Jean François Drège had made an extensive collection of South African plants during an eight-year visit to the Cape Colony. Hooker may be referring to Drège's ‘Geographische Vertheilung’, pp. 38–43, in Drège 1843, which is a table listing the numbers and areas of distribution of families of South African plants. See also the letter to C. J. F. Bunbury [before 9 May 1856].
- f8 1869.f8Probably Edward Forbes's ‘Map of the distribution of marine life, illustrated chiefly by fishes, mollusca, and radiata; showing also the extent & limits of the homoiozoic belts’, published in Alexander Keith Johnston's Physical atlas (E. Forbes 1856).
- f9 1869.f9In a manuscript list headed ‘Kerguelan Lands List of Plants of’ bound into CD's copy of the introductory essay of J. D. Hooker 1853–5 (Darwin Library–CUL), CD wrote next to this species: ‘Hooker says (May 13/56) that he has lost trace of relation of this plant to some Cordillera plant’.
- f10 1869.f10Bentham 1855, a review of Targioni Tozzetti 1850.
- f11 1869.f11Hooker refers to Alphonse de Candolle's long discussion of plants naturalised in Europe, which makes reference to Antonio Targioni Tozzetti's work on the same subject (A. de Candolle 1855, 2: 800).
- f12 1869.f12Samuel Jones Loyd, Baron Overstone.
- f13 1869.f13Hooker planned to propose Thomas Henry Huxley for membership of the Athenæum Club (see letter to J. D. Hooker, 9 May ). Huxley was not elected, however, until 1858 (L. Huxley ed. 1900 1: 150).
- f14 1869.f14Paul Edmund de Strzelecki was a member of the election committee of the Athenæum. Lord Overstone had assisted him in becoming a British subject (DNB).
- f15 1869.f15The number of CD's portfolio of notes on the geographical distribution of plants.
